This is the fourth post in our series on the Microsoft agent platform. We cover the Distribute in M365 pillar — publishing your agents to Microsoft Teams and Microsoft 365 Copilot so they reach users where they already work. All examples reference the FibreOps repository, demonstrated at Microsoft Build BRK241. The Distribution Story Building a great agent is only half the challenge. The other half is getting it into the hands of users without asking them to learn a new tool, visit a new URL, or change their workflow. Microsoft 365 Copilot and Microsoft Teams are where enterprise users already spend their day, making them the natural distribution surface for agents. With the GA release, publishing an agent to Teams and M365 Copilot is a single command. No separate app registration portal, no manual manifest assembly, no multi-step approval workflow for development and testing. Publishing to Microsoft 365 Copilot (GA) FibreOps ships as a declarative agent + action plugin ready for sideload. A single CLI command produces the complete package: python -m fibreops.demo publish-m365 --out dist/m365 # Output: # ✓ wrote dist/m365/declarativeAgent.json # ✓ wrote dist/m365/fibreops-action.json # ✓ wrote dist/m365/manifest.json # ✓ wrote dist/m365/color.png (192x192) # ✓ wrote dist/m365/outline.png ( 32x32) # ✓ wrote dist/m365/fibreops-copilot.zip What Gets Generated File Purpose declarativeAgent.json Defines the agent's persona, capabilities, and conversation starters for M365 Copilot fibreops-action.json Action plugin that proxies tool calls to the deployed FastAPI backend via OpenAPI manifest.json Teams app manifest with publisher metadata, permissions, and capabilities color.png / outline.png App icons for Teams and M365 surfaces fibreops-copilot.zip Ready-to-upload package for Teams Admin Center Configuration Set the base URL to your deployed FastAPI app before publishing — the action plugin uses this to resolve the OpenAPI runtime: # Set the public HTTPS hostname of the deployed FastAPI app $env:M365_ACTION_BASE_URL = "https://fibreops-demo.azurewebsites.net" # Optional: customise publisher metadata $env:M365_PUBLISHER_NAME = "Contoso Network Operations" $env:M365_PUBLISHER_WEBSITE = "https://contoso.com/noc" # Generate the package python -m fibreops.demo publish-m365 --out dist/m365 Environment Variable Purpose M365_ACTION_BASE_URL Public HTTPS root for the FastAPI /openapi.json (e.g., Container Apps FQDN) M365_APP_ID Override the generated Teams app GUID (default: deterministic per repo) M365_PUBLISHER_NAME Publisher name shown in M365 Admin Center M365_PUBLISHER_WEBSITE Publisher website link Uploading the Package Upload the generated fibreops-copilot.zip through either path: Teams Admin Center → Manage apps → Upload new app M365 Admin Center → Integrated apps → Upload custom apps Once uploaded, the declarative agent: Inherits the publisher metadata you configured Advertises conversation starters from the FibreOps deck (e.g., "What is the current outage status?", "Dispatch an engineer to FN-LDN-001") Proxies tool calls to the deployed FastAPI app via the action plugin Appears in Microsoft 365 Copilot as a specialised agent users can invoke How Declarative Agents Work A declarative agent in Microsoft 365 Copilot is defined by metadata rather than code running in the M365 surface. The intelligence lives in your backend — Copilot handles the conversational UX, tool orchestration schema, and user authentication. The flow: User invokes the agent in Microsoft 365 Copilot or Teams Copilot renders conversation starters and accepts natural language input When the agent needs to act, Copilot calls the action plugin (your OpenAPI endpoint) Your FastAPI backend processes the request using the full agent pipeline Results return to the user in the Copilot/Teams UX This architecture means your agent logic stays in one place — the backend. The M365 surface is purely a distribution and interaction layer. Action Plugins and OpenAPI The action plugin ( fibreops-action.json ) references your FastAPI app's /openapi.json endpoint. FibreOps exposes a JSON API that the action plugin can call: /api/runs — List and query agent runs /api/optimiser — Get optimizer scores and suggestions /sdk/chat — Natural language interaction with the agent system /healthz — Liveness probe Because FastAPI auto-generates OpenAPI schemas from your typed Python endpoints, the action plugin gets accurate parameter descriptions, response schemas, and error codes without any manual specification work. Publishing as Autopilots (Public Preview) Autopilots take distribution one step further — agents that operate autonomously without requiring a user to initiate each interaction. An Autopilot can: React to events (e.g., a critical telemetry signal) without human initiation Take actions within defined guardrails Notify users only when human intervention is needed Operate continuously across Microsoft 365 surfaces For FibreOps, an Autopilot would monitor the Event Hub stream continuously and only surface to the NOC team when an incident exceeds automated resolution capability — a fully autonomous operations agent. Teams Adaptive Cards FibreOps posts rich Adaptive Card notifications to Microsoft Teams throughout the agent pipeline. This is separate from the declarative agent — it is a push notification channel for real-time operational awareness. # The NetOps agent posts an outage notice via Incoming Webhook def post_outage_notice(incident_id, node_id, severity, summary, engineer=None): card = { "type": "AdaptiveCard", "body": [ {"type": "TextBlock", "text": f"🚨 Outage: {node_id}", "weight": "Bolder", "size": "Large"}, {"type": "FactSet", "facts": [ {"title": "Severity", "value": severity.upper()}, {"title": "Incident", "value": incident_id}, {"title": "Summary", "value": summary}, ]}, ], "actions": [ {"type": "Action.OpenUrl", "title": "View in NOC Console", "url": f"{base_url}/runs/{incident_id}"} ] } # POST to Teams webhook or append to outbox for offline mode ... If TEAMS_WEBHOOK_URL is not configured, cards are appended to state/teams_outbox.jsonl for review in the NOC console's Teams panel. End-to-End: From Code to Copilot Here is the complete flow from development to distribution: Build — Develop agents with Microsoft Agent Framework, test locally with python -m fibreops.demo --backend local Publish agents — python -m fibreops.demo publish creates hosted Prompt Agents in Foundry Deploy infrastructure — azd up provisions App Service, ACR, Event Hub, Key Vault, and Application Insights Deploy hosted agent — azd env set FIBREOPS_DEPLOY_HOSTED true && azd up Generate M365 package — python -m fibreops.demo publish-m365 --out dist/m365 Upload to Teams — Upload fibreops-copilot.zip via Teams Admin Center Users interact — The agent is now available in Microsoft 365 Copilot and Teams Security Considerations Managed Identity — The deployed app uses system-assigned managed identity for all Azure service access. No secrets in code. Least privilege — Each role grant is scoped to the minimum required (Event Hubs Data Owner, Key Vault Secrets User, AcrPull, Azure AI Developer). Authentication — The M365 Copilot surface handles user authentication; your backend receives authenticated requests. Guardrails — Autopilots operate within defined boundaries; human-in-the-loop escalation is built into the Routine and agent decision logic. Key Takeaways Publishing to Teams and M365 Copilot is GA — a single command generates the complete package. Declarative agents separate distribution (M365) from intelligence (your backend). Action plugins leverage your existing FastAPI OpenAPI schema — no manual specification needed. Autopilots (Public Preview) enable fully autonomous operation within guardrails. Adaptive Cards provide real-time push notifications alongside the conversational agent surface. The same backend serves the NOC console, the Copilot SDK, and the M365 declarative agent.

This is the second post in our series on the Microsoft agent platform. Here we dive deep into building autonomous agents, the development experience, the Microsoft Agent Framework, tool design patterns, and how the GitHub Copilot SDK brings conversational AI to your agent system. All examples reference the FibreOps repository, an autonomous fibre outage response system demonstrated at Microsoft Build BRK241. The Microsoft Agent Framework The Microsoft Agent Framework (now GA) provides a unified programming model for building agents. It supports multiple backends through a single .run() contract: Hosted — FoundryAgent connected to a Prompt Agent published to Microsoft Foundry Agent Service. Foundry — Agent + FoundryChatClient with the definition resolved locally (ideal for prompt iteration). Local — Deterministic LocalAgent for offline development and testing. This design means your orchestration code never changes regardless of where the agent runs. The factory pattern in FibreOps selects the backend at startup: # src/fibreops/agents/factory.py — simplified from agent_framework_foundry import FoundryAgent from agent_framework import Agent, FoundryChatClient def build_agent(role: str, backend: str, config: Config): if backend == "hosted": return FoundryAgent(agent_id=config.foundry_agents[role]) elif backend == "foundry": return Agent( instructions=get_instructions(role), chat_client=FoundryChatClient(endpoint=config.endpoint), tools=get_tools(role), ) else: return LocalAgent(role=role) Set FIBREOPS_AGENT_BACKEND to override the backend, or leave it as auto for intelligent detection. Designing Role-Specialised Agents FibreOps demonstrates a key pattern: role specialisation. Rather than one monolithic agent, the system uses three focused agents, each with a clear responsibility boundary: Agent Role Tools Available IncidentAnalysisAgent Classify severity, find root cause, retrieve SOP Knowledge (SOPs + topology), Web IQ, Work IQ NetOpsCoordinatorAgent File D365 incident, post Teams notice Ticketing, Teams, Memory FieldDispatchAgent Select engineer, book resource, update team Dispatch, Teams, Voice Why Role Specialisation? Focused system prompts — Each agent has a tightly scoped instruction set, reducing hallucination and improving reliability. Independent evaluation — You can score each agent separately against role-specific criteria. Parallel development — Teams can iterate on agents independently. Selective upgrade — Swap one agent's model or implementation without touching others. Tool Design: Typed Python Functions Tools in the Microsoft Agent Framework are typed Python functions that the runtime supplies to the hosted agent definition. FibreOps demonstrates several tool categories: Knowledge Tools # src/fibreops/tools/knowledge.py — simplified def sop_lookup(node_id: str, signal_type: str) -> dict: """Retrieve the Standard Operating Procedure for a given signal type. Args: node_id: The fibre node identifier (e.g., FN-LDN-001) signal_type: The type of signal (loss_of_light, high_ber, signal_degradation) Returns: SOP with steps, escalation path, and estimated resolution time. """ # Load from local markdown SOPs or Foundry IQ ... def web_iq_search(query: str, *, limit: int = 5) -> list[dict]: """Search public web for context relevant to the incident. Grounding against roadworks, weather, power outages, splice guidance. Falls back to deterministic fixtures when endpoint is unset. """ ... def work_iq_search(query: str, *, limit: int = 5) -> list[dict]: """Search enterprise knowledge for context relevant to the incident. Site surveys, SLA tiers, competency matrix, MTTR trends. """ ... Integration Tools # src/fibreops/tools/teams.py — simplified def post_outage_notice( incident_id: str, node_id: str, severity: str, summary: str, engineer: str | None = None, ) -> dict: """Post an Adaptive Card outage notice to the configured Teams channel. If TEAMS_WEBHOOK_URL is not set, appends to state/teams_outbox.jsonl for offline review. """ card = build_adaptive_card(incident_id, node_id, severity, summary, engineer) if config.teams_webhook_url: requests.post(config.teams_webhook_url, json=card) else: append_to_outbox(card) return {"status": "posted", "incident_id": incident_id} Design Principles for Agent Tools Typed parameters with docstrings — The runtime uses type hints and docstrings to generate the tool schema for the LLM. Graceful degradation — Every tool works offline by falling back to local fixtures or file-based state. Idempotent where possible — Tools that create resources return existing records if called with the same parameters. Observable — Every tool invocation emits an OpenTelemetry span for tracing and debugging. The Orchestrator Pattern The orchestrator drives signals through the agent pipeline. It is deliberately simple — a linear flow with error handling: # src/fibreops/orchestrator.py — simplified async def handle_signal(signal: TelemetrySignal) -> RunResult: """Process a telemetry signal through the agent pipeline.""" # Stage 1: Incident Analysis analysis = await incident_agent.run( f"Analyse this signal: {signal.model_dump_json()}" ) # Stage 2: NetOps Coordination coordination = await netops_agent.run( f"Coordinate response for: {analysis.summary}" ) # Stage 3: Field Dispatch dispatch = await dispatch_agent.run( f"Dispatch engineer for incident: {coordination.incident_id}" ) return RunResult( signal=signal, analysis=analysis, coordination=coordination, dispatch=dispatch, ) The orchestrator honours the same contract regardless of backend — hosted , foundry , or local — because all backends implement await agent.run(prompt) . GitHub Copilot SDK Integration (GA) The GitHub Copilot SDK enables conversational interaction with your agent system. FibreOps implements FibreOpsCopilotClient with the same interface as github/copilot-sdk : # src/fibreops/sdk/__init__.py — simplified from fibreops.sdk.client import FibreOpsCopilotClient client = FibreOpsCopilotClient() session = client.create_session() # Query agent status response = session.send_and_wait("status") print(response.text) # Human-readable summary print(response.data) # Structured JSON # Inject a telemetry signal via conversation response = session.send_and_wait(json.dumps({ "signal_id": "sig-demo", "node_id": "FN-LDN-001", "signal_type": "loss_of_light", "severity": "critical" })) The adapter routes prompts by shape: JSON signal-shaped dicts — Forwarded to the orchestrator for processing. Free-form text — Answered by a deterministic responder ( help , status , nodes , engineers , optimiser , dispatch ). Drive it from the terminal: python -m fibreops.demo chat "help" python -m fibreops.demo chat "status" python -m fibreops.demo chat '{"signal_id":"sig-demo","node_id":"FN-LDN-001","signal_type":"loss_of_light","severity":"critical"}' Or hit the embedded HTTP endpoint when the NOC console is running: Invoke-RestMethod -Method Post http://127.0.0.1:8800/sdk/chat -Body '{"prompt":"status"}' -ContentType application/json Development Workflow with Foundry Toolkit for VS Code The Foundry Toolkit for VS Code provides an integrated development experience: Author prompts — Edit system instructions with live preview and token counting. Test locally — Run against the foundry backend with FoundryChatClient pointing at your development model. Iterate fast — The foundry backend resolves definitions locally, so prompt changes take effect immediately without republishing. Publish when ready — python -m fibreops.demo publish creates hosted Prompt Agents in Foundry. Multi-Model Support The Microsoft Agent Framework supports multiple models. FibreOps defaults to gpt-4.1-mini (the model available in most demo Foundry accounts), but any chat-completions deployment works: # .env AZURE_AI_MODEL_DEPLOYMENT=gpt-4.1-mini # or gpt-4o-mini, gpt-4o, gpt-4.1 The framework also supports Claude Code connectors and Magentic-One for multi-agent collaboration scenarios. Testing Strategy FibreOps demonstrates a layered testing approach: Unit tests — Test tools in isolation with mocked dependencies. Local backend tests — Run the full pipeline with LocalAgent for deterministic assertions. Integration tests — Run against real Foundry agents with pytest -q . Rubric evaluation — The optimizer scores every run against defined criteria. # Run the test suite .\.venv\Scripts\python.exe -m pytest -q Key Takeaways The Microsoft Agent Framework provides a unified .run() contract across hosted, foundry, and local backends. Role specialisation keeps agents focused, testable, and independently evolvable. Tools are typed Python functions with docstrings — the runtime generates schemas automatically. The GitHub Copilot SDK (GA) enables conversational interaction with any agent system. Graceful degradation means the entire system works offline for development. The factory pattern lets you switch backends without changing orchestration code. Next Steps Clone the FibreOps repository and run python -m fibreops.demo --signals 3 Microsoft Agent Framework documentation Next in this series: Running Hosted Agents in Microsoft Foundry Agent ServiceBuilding and Deploying Microsoft Hosted Agents to Microsoft Teams
A practical, engineer-to-engineer guide to taking an AI agent from a developer laptop, into Microsoft Foundry Agent Service, and out to end users inside Microsoft Teams and Microsoft 365 — using the BRK241 FibreOps reference implementation as a worked example. Introduction: the hard part is no longer building the agent Two years ago, wiring an LLM to a couple of tools felt like the summit. It isn't any more. Frameworks, hosted models, and function-calling have made the build step almost routine. The problem has quietly moved downstream. The genuinely hard questions today are operational: Where does the agent run when it's no longer on your machine? What identity does it use to call enterprise systems, and who granted it? How does a platform team scale, monitor, and roll it back? How do business users actually reach it without learning a new tool? Who signed off on it touching production data? A prototype answers none of these. A production agent platform answers all of them, repeatably, for every agent an organisation ships. That shift — from a clever notebook to a governed, observable service that lands in the tools people already use — is the subject of this article. We'll use a single narrative to keep it concrete: FibreOps, the BRK241 "Autonomous Fibre Outage Response" system. It ingests optical line terminal (OLT) telemetry, analyses incidents, files tickets in Dynamics 365 Field Service, posts Adaptive Cards to Microsoft Teams, and dispatches engineers — all through role-specialised agents. The full source is on GitHub. The story runs on three verbs: Build → Run → Distribute. Section 1: Building the agent An agent is not one mega-prompt. FibreOps is deliberately factored into three role-specialised agents behind a single orchestrator, each with its own tool surface, its own system instructions, and a strict output contract: IncidentAnalysisAgent — classifies severity, finds probable cause, and pulls the correct standard operating procedure (SOP). NetOpsCoordinatorAgent — files the D365 incident and posts the Teams outage notice. FieldDispatchAgent — selects the best engineer by skill, region and shift, books the resource, and updates Teams. The Coordinator hands off to Dispatch with a literal HANDOFF:DISPATCH token rather than a fuzzy "I think we should…". Hard contracts between agents are how you stop them inventing work. Microsoft Agent Framework The agents are built with the Microsoft Agent Framework (MAF). The key design decision in the reference implementation is that all three backends honour one contract — await agent.run(prompt) -> response — so the orchestrator never knows or cares where reasoning actually happens: local — a deterministic LocalAgent shim with no LLM, so the demo runs with zero Azure credentials. foundry — agent_framework.Agent + FoundryChatClient , definition resolved locally. Ideal while iterating on prompts. hosted — agent_framework_foundry.FoundryAgent bound to a Prompt Agent published to Foundry Agent Service. This is the production path. Building a Foundry-backed agent is just a client plus instructions plus typed tools: from agent_framework import Agent from agent_framework_foundry import FoundryChatClient from azure.identity import DefaultAzureCredential client = FoundryChatClient( project_endpoint=settings.azure_ai_project_endpoint, model=settings.azure_ai_model_deployment, # e.g. gpt-4.1-mini credential=DefaultAzureCredential(), # no connection strings, ever ) agent = Agent( client=client, instructions=INCIDENT_ANALYSIS_INSTRUCTIONS_V1, name="IncidentAnalysisAgent", tools=[lookup_sop, recall, remember, web_iq_search, work_iq_search], ) Note the DefaultAzureCredential . There are no keys or connection strings anywhere in the reasoning path — identity flows from Microsoft Entra ID. Keep that in mind; it becomes the backbone of the governance story later. Tool calling and MCP Every tool is a typed Python function. Foundry sees the JSON schema derived from the signature; the runtime executes the Python. That separation matters: the published agent definition stores only the model and instructions, while the implementations are supplied by the runtime on every call. The same in-process tools (Teams, D365, dispatch, knowledge, memory) run identically whether the agent is local or hosted. Beyond your own functions, Foundry agents can draw on hosted toolbox tools ( web_search , code_interpreter ) and Model Context Protocol (MCP) servers. MCP is the open standard for exposing tools, resources and prompts to agents over a uniform protocol, so an enterprise can stand up an MCP server once and let every agent consume it. In FibreOps this is config-gated — set FIBREOPS_FOUNDRY_TOOLBOX=1 and the incident analyst gains live web search alongside its Web IQ / Work IQ connectors, with no code change. Grounding strategies FibreOps grounds reasoning three ways, in layers: Retrieval over owned knowledge — SOPs (markdown) and the fibre-node topology graph, looked up by the analysis agent. Foundry IQ — Web IQ for public context (roadworks, weather, power) and Work IQ for enterprise context (site surveys, SLA tiers, competency matrix). Procedural memory — prior incidents for a node, recalled before analysis so the agent learns from history. Crucially, when the IQ endpoints are unset the tools fall back to deterministic fixtures so the agent always grounds. Grounding that silently fails is worse than no grounding; design your fallbacks explicitly. Local development, testing and evaluation The whole system runs from one command with no cloud dependency: # Deterministic local backend — no Azure credentials required python -m fibreops.demo --signals 3 --backend local Every run is persisted as a JSON document — the input signal, every agent step, every tool call, every output, every ticket. That single artefact shape feeds three consumers: structured logs, the local optimiser, and Foundry Evaluators. The optimiser scores each run against a five-criterion rubric (was the analysis complete, was severity consistent with customer impact, did a ticket land, did dispatch policy match severity, was an SOP cited) and writes back concrete improvement suggestions. That evaluation loop — not the first working demo — is what turns a prototype into a system you can keep improving. Section 2: Deploying to Microsoft Foundry Agent Service Microsoft Foundry Agent Service is the managed runtime that hosts your agents. It gives you a secure, isolated execution environment, an agent runtime that speaks the OpenAI-compatible Responses API, plus hosted memory, toolboxes, knowledge integrations, and observability — without you operating any of it. FibreOps demonstrates the two hosting shapes Foundry offers. Shape 1 — Prompt Agents A Prompt Agent stores a model deployment plus system instructions as an immutable, versioned definition in Foundry. Publishing is a one-time step per change: from azure.ai.projects import AIProjectClient from azure.ai.projects.models import PromptAgentDefinition from azure.identity import DefaultAzureCredential pc = AIProjectClient(endpoint=endpoint, credential=DefaultAzureCredential(), allow_preview=True) pc.agents.create_version( agent_name="fibreops-incident-analysis", definition=PromptAgentDefinition( model=model_deployment, instructions=INCIDENT_ANALYSIS_INSTRUCTIONS_V1, ), description="FibreOps incident analysis agent", ) At run time you bind to the published version with a FoundryAgent , and — as noted above — the runtime supplies the tool implementations. Prompt versioning ( instructions_v1 , _v2 , _v3 ) is where the optimiser's suggestions land, closing the improvement loop inside the platform. Shape 2 — Containerised hosted agents The BRK241 hero path packages the entire analyse → coordinate → dispatch flow as a single hosted agent: a container that serves the Responses /responses contract on port 8088, deployed straight into your Foundry project. The Agent Framework agent is wrapped by ResponsesHostServer : from agent_framework_foundry_hosting import ResponsesHostServer def main() -> None: server = ResponsesHostServer(build_system_agent()) # Foundry sets the reserved PORT env var inside the sandbox server.run(host="0.0.0.0", port=8088) The container is declared in agent.yaml — kind: hosted , the image reference, the per-session sandbox size (0.5/1 Gi, 1/2 Gi or 2/4 Gi), the protocol version, and only user-declared environment variables. You never hard-code FOUNDRY_* values or the Application Insights connection string; the platform injects those at run time. Deployment registers the image as an immutable version and polls until active : details = pc.agents.create_version( agent_name="fibreops-outage-response", definition=HostedAgentDefinition( protocol_versions=[ProtocolVersionRecord( protocol=AgentProtocol.RESPONSES, version="1.0.0")], cpu="1", memory="2Gi", container_configuration=ContainerConfiguration(image=image), environment_variables={"MODEL_DEPLOYMENT_NAME": model_deployment}, ), ) From local execution to managed hosting The migration path is deliberately gentle because the contract never changes. A developer iterates locally against LocalAgent , moves to the foundry backend to test real prompts, then publish es Prompt Agents or builds and deploy-hosted s the container. The orchestrator code is byte-for-byte identical across all three. That property — same code path local for dev, hosted in Foundry for prod — is the single most important thing to preserve when designing your own agents. Scaling, memory, toolboxes, knowledge and observability Scaling — Foundry provisions a per-session sandbox and a dedicated Entra agent identity per hosted-agent version; you size the sandbox in agent.yaml and let the platform handle isolation. Memory — set FOUNDRY_MEMORY_STORE_NAME and a FoundryMemoryProvider is attached as a context provider so agents read and write learned procedures in Foundry's hosted store; unset, they use local SQLite. No code change. Toolboxes & knowledge — hosted web_search , code interpreter, MCP, and Web/Work IQ connectors are curated per role and merged with your Python tools. Observability — the agent emits OpenTelemetry spans; set APPLICATIONINSIGHTS_CONNECTION_STRING (injected by the platform for hosted agents) and every agent decision, tool call and latency is queryable in Application Insights. Section 3: IT and development responsibilities Successful agent deployments need both developer velocity and platform governance. The failure mode at either extreme is familiar: developers who can't ship because every request routes through a ticket queue, or a free-for-all where nobody can say what identity an agent runs as. The workable model draws a clean line of responsibility. Concern Developer / Agent team IT / Platform team Identity Use DefaultAzureCredential ; never embed secrets; declare the scopes the agent needs Provision the managed / Entra agent identity; own the app registration and consent Access control Request least-privilege roles for the tools the agent calls Grant RBAC at the correct scope; run role-assignment scripts; enforce approvals Security Validate inputs, handle tool failures cleanly, avoid data exfiltration in prompts Disable ACR admin, enforce managed-identity pulls, network controls, Key Vault for secrets Compliance Keep decisions explainable and replayable (the JSON run record) Data-residency, retention, audit, Responsible AI review sign-off Monitoring Emit structured traces + OTel spans; define the rubric Own Application Insights / Log Analytics, alerting, dashboards, SLOs Cost Right-size the sandbox and model deployment; cache grounding Budgets, quota, token-consumption monitoring, chargeback Lifecycle Version prompts and images; feed the optimiser back into new versions Environment promotion (dev → test → prod), rollback, deprecation The reference implementation encodes this split honestly. The Bicep template does not create role assignments, because most deployers only hold Contributor . Instead a subscription Owner runs scripts/grant-mi-roles.ps1 once to grant the App Service's identity exactly the roles it needs — Event Hubs Data Owner, Key Vault Secrets User, AcrPull, Azure AI Developer, and Cognitive Services OpenAI User — and no more. That is least privilege made operational. Section 4: Publishing to Microsoft Teams and Microsoft 365 An agent nobody can reach has no value. The final verb — Distribute — puts the agent where users already work. FibreOps reaches Teams two ways. The lightweight path: Adaptive Cards via Incoming Webhook The NetOps coordinator posts outage notices and status updates to a Teams channel as Adaptive Cards through an Incoming Webhook. Any unconfigured channel is logged to state/teams_outbox.jsonl , so the same code runs in a demo and in production — you only change the webhook target. This is the fastest way to get agent output into Teams and is ideal for notifications and human-in-the-loop review. The rich path: a declarative agent for Microsoft 365 Copilot To make the agent conversational and discoverable across Teams, Microsoft 365 Copilot and copilot.microsoft.com, FibreOps ships as a declarative agent plus an API plugin action. One command builds the sideload-ready package: python -m fibreops.demo publish-m365 --out dist/m365 # wrote declarativeAgent.json (name, description, conversation starters) # wrote fibreops-action.json (API plugin -> {base_url}/openapi.json) # wrote manifest.json (Teams app manifest) # wrote color.png / outline.png (icons) # wrote fibreops-copilot.zip (upload this) The declarative agent declares metadata, conversation starters and a capability set; the action plugin proxies tool calls to the deployed FastAPI app via its OpenAPI document. Set M365_ACTION_BASE_URL to the app's public HTTPS root before publishing — the CLI warns when the placeholder is still in effect. That single environment variable is the only thing that flips the package from demo to production. The end-to-end distribution workflow Conceptually, the artefact travels a fixed pipeline: Developer laptop │ build + test (local backend) → publish Prompt Agent / deploy hosted container ▼ Microsoft Foundry Agent Service │ hosted agent, secure sandbox, Entra agent identity, observability ▼ Teams App package (fibreops-copilot.zip) │ Teams Admin Center → Manage apps → Upload (or M365 Admin Center → Integrated apps) ▼ Microsoft 365 tenant │ admin approval, availability policy, targeted rollout ▼ End user in Teams / M365 Copilot Enterprise rollout is rarely "publish to everyone". The realistic pattern is a staged one: sideload to a pilot group, gather feedback and optimiser scores, then widen availability through Teams app-permission and app-setup policies to department, then tenant. Because the package carries publisher metadata and the declarative schema, IT can review it exactly like any other line-of-business app. Section 5: Enterprise governance Governance is not a bolt-on; in this architecture it's a property of the platform. The pillars: Entra ID integration and agent identity — every hosted agent version gets a dedicated Entra agent identity. Nothing authenticates with a shared key. DefaultAzureCredential means the same code picks up a developer's identity locally and the managed identity in production. RBAC at the right scope — roles are granted to identities, not baked into images. Deploying a hosted agent requires Azure AI Project Manager at project scope; the Foundry project identity needs AcrPull on the registry to pull the container. Least privilege is enforced, not assumed. Auditability — the JSON run record plus OpenTelemetry spans in Application Insights give you a replayable, per-incident audit trail. You can reconstruct exactly which SOP was cited, which engineer was chosen, and why severity was escalated. Data boundaries — the mock D365 is a drop-in for a real Dataverse environment; grounding sources are enterprise connectors (Work IQ) kept inside the tenant boundary. Nothing leaves the subscription without an explicit connector. Responsible AI — the Adaptive Card JSON can be pasted into the Adaptive Cards designer for governance review; the evaluation rubric makes quality measurable; explicit grounding fallbacks prevent silent failure. Production readiness — immutable versioning, one-command rollback (delete a version), managed-identity-only image pulls, and disabled ACR admin credentials are all first-class in the reference deployment. Section 6: Reference architecture The following diagram shows the production topology — users on the left, enterprise systems and controls on the right, with Foundry Agent Service at the centre hosting the agent. flowchart LR User["NOC operator / business user"] subgraph M365["Microsoft 365 tenant"] Teams["Microsoft Teams(Adaptive Cards + declarative agent)"] Copilot["Microsoft 365 Copilot"] end subgraph Foundry["Microsoft Foundry Agent Service"] Hosted["Hosted AgentOutage Response System(secure per-session sandbox)"] Runtime["Agent runtime(Responses API)"] Memory["Hosted memory + toolboxes"] end subgraph Enterprise["Enterprise data & tools"] MCP["MCP servers / web_search"] D365["Dynamics 365 Field Service"] EventHub["Azure Event Hubs(OLT telemetry)"] Knowledge["SOPs + topology + Web/Work IQ"] end subgraph Ops["Cross-cutting"] Obs["ObservabilityApp Insights / OTel"] Gov["GovernanceEntra ID · RBAC · audit"] end User --> Teams User --> Copilot Teams --> Runtime Copilot --> Runtime Runtime --> Hosted Hosted --> Memory Hosted --> MCP Hosted --> Knowledge Hosted --> D365 EventHub --> Hosted Hosted -.->|Adaptive Cards| Teams Hosted --> Obs Gov -.->|identity & policy| Foundry Gov -.->|identity & policy| Enterprise Read the solid arrows as the control/orchestration flow and the dashed arrows as governance and outbound notifications. The point of the diagram is that governance (Entra ID, RBAC, audit) applies across every component, and observability captures every agent decision — neither is optional plumbing. Section 7: What production looks like Picture the FibreOps rollout at a national fibre operator, with the four personas doing their part: Developers build the three agents and the orchestrator on their laptops against the local backend — no cloud, no credentials, deterministic tests. They tune prompts against the foundry backend, watch the optimiser rubric climb from 0.90 to 1.0 as they add the ">5,000 customers ⇒ escalate to critical" rule, and commit a new instruction version. The platform team deploys the container to Foundry Agent Service via scripts/deploy-hosted-agent.ps1 , which builds the image in ACR, pushes it, and registers an immutable version. They provision the Event Hub, Key Vault, Log Analytics and Application Insights from Bicep, and size the sandbox at 1 vCPU / 2 GiB. IT approves the workload: a subscription Owner grants the managed identity its five least-privilege roles, hardens the App Service to pull via managed identity, disables ACR admin, and signs off the Responsible AI review using the replayable run records and the Adaptive Card previews. They sideload fibreops-copilot.zip to a pilot channel first. Business users consume it inside Teams. When an OLT in London loses light, an Adaptive Card appears in the NOC channel within seconds — severity, probable cause, ticket ID, and the dispatched engineer's ETA — with no human having read a dashboard, opened a ticket, or phoned a dispatcher. If Foundry ever wobbles, the same system falls back to the deterministic local agent with an identical trace shape. Every integration but D365 is live in the demo, and D365 is a one-variable swap to a real Dataverse endpoint. That is the whole point: the demo and production differ by configuration, not by code. Key takeaways Design for one contract. If agent.run(prompt) behaves identically local, foundry-backed and hosted, migration to production is configuration, not a rewrite. Factor agents by role with hard handoff contracts. Literal tokens like HANDOFF:DISPATCH beat fuzzy natural-language handoffs and stop agents inventing work. Never embed secrets. DefaultAzureCredential + Entra agent identities give you keyless auth that works the same everywhere. Make every run replayable. A single JSON artefact that feeds logs, evaluation and audit is worth more than any dashboard. Ground explicitly, and design your fallbacks. Grounding that fails silently is a liability; deterministic fixtures keep the agent honest. Split responsibility cleanly. Developers own velocity and quality; the platform team owns identity, scale, cost and promotion. Encode the split in scripts, not tribal knowledge. Version prompts and images immutably. Rollback should be "delete a version", and the optimiser's suggestions should land as the next version. Distribute where users already are. Adaptive Cards for notifications, a declarative agent for conversation and discovery across Teams and M365 Copilot. Roll out in stages. Pilot channel → department → tenant, gated by app policies and real optimiser scores.

Some of the most valuable work still lives inside a browser: booking a class, pulling a figure off a dashboard, filling in a portal form, gathering research across a dozen tabs. These are exactly the tasks people wish an agent could just do. On 22 July 2026 at 2:30 PM BST (7:00 PM IST), the Microsoft Foundry community is running a 40‑minute Discord round table on the Browser Automation tool : how how it helps agents complete real browser workflows, where you see risk or friction, and what samples, docs, and product improvements would help you adopt it. This is a discussion, not a slideshow. Bring your real projects : the the web workflows you'd love to hand off, and the guardrails you'd want first.

The problem: the last mile of automation still runs in a browser Most real-world workflows eventually hit a website with no clean API , such as a supplier portal, an internal admin console, a booking page, or a legacy dashboard a supplier portal, an internal admin console, a booking page, a legacy dashboard. Traditional scripting can automate these, but selectors break, pages change, and every new site means another brittle script to maintain. What developers actually want is an agent that can look at a page, decide what to do, and do it : navigate, read, click, type, and hand back a structured result navigate, read, click, type, and hand back a structured result. That's the gap the Browser Automation tool in Microsoft Foundry is built to close , and doing it responsibly and doing it responsibly, with the right safeguards, is a big part of why we want your feedback. What is the Browser Automation tool? The Browser Automation Tool (BAT) gives Foundry agents the ability to drive a real browser to complete web workflows. It's available as an MCP tool, and it uses Playwright Workspaces , a generally available, cloud-scale service, a generally available, cloud-scale service : navigating, clicking at coordinates, typing, and applying filters as its headless browser infrastructure. When an agent gets a request, Foundry spins up an isolated, sandboxed browser session per interaction, so each run is private and segregated. How agents actually interact with a page BAT runs a perception–action loop. The model receives the current state of the page (including screenshots), decides the next action, and BAT executes it in the sandbox using Playwright and real oversight navigating, clicking at coordinates, typing, applying filters. After each action, BAT captures the updated state and sends it back to the model, repeating until the goal is met or the user stops. Because the model can parse HTML into a DOM, it can reason about the page rather than follow a fixed script. It also supports multi-turn conversations, so you can refine a request mid-flow to complete form-filling or scraping scenarios. Built for real use : watch the automation happen in real time for debugging. and real oversight Live View : a human-in-the-loop override for ambiguous or sensitive steps. watch the automation happen in real time for debugging.

Broad SDK support , and the agent can make mistakes or be misled by malicious page content Python, C#, JavaScript, Java, and the REST API. A word on responsible use. BAT is powerful precisely because an AI can use credentials you share with it to reach email, financial, enterprise, or social accounts , watching for and the agent can make mistakes or be misled by malicious page content. You're responsible for reviewing your applications, scoping which credentials you provide, and adding your own mitigations. See the Foundry Agent Service transparency note. This is exactly the kind of trade-off we want to talk through together. Example scenario A user asks: "Report the year-to-date percent change of Microsoft's stock price." The agent navigates to a finance site, enters MSFT in the search bar, opens the stock page, clicks the YTD view on the chart, reads the value, and returns a clean, structured answer ; that's the no bespoke scraper, no hard-coded selectors, and a full trace of what it did. Discussion prompt: "Where would browser automation fit into your current projects or workflows?" How setup works (the short version) You'll want to understand the wiring before you scale, so it's worth a look ahead of the session. There are two moving parts: Create a Playwright Workspace in the Azure portal, enable the access token auth method, and grab the wss:// browser endpoint. Give your project identity a Contributor (or custom) role on the workspace. Connect the tool in Foundry under Build > Tools: create a toolbox, add Browser Automation, point it at your Playwright workspace and auth type, and publish.

Building AI Agents from Zero to Production Most agent demos stop at "it answered my question." Production doesn't. The gap between a notebook that calls an LLM and a governed, observable, multi-agent system your organisation can actually depend on is where real engineering happens, evaluation, deployment, data sovereignty, tool governance, and cross-team interoperability. Microsoft's open-source course Building AI Agents from Zero to Production walks that entire arc in seven lessons, using one realistic use case and the Microsoft Agent Framework (MAF) plus Microsoft Foundry. This post is a developer-focused tour of what it teaches, the architecture decisions behind each stage, and the code patterns that matter when you move from prototype to production. Who this is for AI engineers building their first or first production, agent system. Backend and full-stack developers integrating agents into real applications and CI/CD. Cloud architects who need data sovereignty, private networking, and governance around agent workloads. Technical leads deciding how to standardise tools and orchestration across multiple teams. The samples are Python 3.12+, served through Microsoft Foundry using GPT-5 series models (for example gpt-5.1 ). Lesson 4 adds a TypeScript/React frontend. You will want an Azure subscription and the Azure CLI. The AI Agent Development Lifecycle The course is organised around a lifecycle rather than a feature list. Each lesson is a stage, and each stage assumes the previous one is solved: # Stage The production question it answers 1 Agent Design What should each agent do, and how do they hand off? 2 Agent Development How do I build and run them with the Agent Framework? 3 Agent Evaluations How do I know they actually work — and keep working? 4 Agent Deployment How do I ship one as a hosted service with a UI and CI gate? 5 Production Hosted Agents How do I meet enterprise data, network, and governance needs? 6 Microsoft Toolbox How do I govern tools once, and reuse them across teams? 7 Multi-Agent & A2A How do agents from different teams interoperate safely? The thread running through all seven is a single scenario: a Developer Onboarding agent system that helps a new hire find the right teammates, get a sensible first task, and pull learning resources and code snippets. It is deliberately mundane, which is exactly why it exposes the production concerns that flashy demos hide. Lesson 1 — Agent Design: three components, one graph The course defines an agent by three parts: an LLM for reasoning, tools to act, and memory to retain context. The design work is context engineering — making sure the right information reaches the model at the right moment, no more and no less. Rather than one monolithic assistant, the onboarding system is split into specialists coordinated by a triage agent using handoff orchestration: Agent Job Tool Employee Search Answer org and people questions Foundry file search over an employee-directory vector store Task Recommendation Suggest 1–3 GitHub issues for the new dev GitHub MCP Server (reads recent commits + open issues) Code Assistant Provide resources and runnable snippets Microsoft Learn MCP + Code Interpreter Architecturally this is a directed graph: User → Triage → [Employee, Learning, Coding] . Splitting responsibilities early pays off later, each agent gets a tightly scoped prompt (less hallucination), can be evaluated independently, and can be upgraded without touching its peers. Lesson 2 — Development: standalone agents with MAF Here the design becomes code. Each specialist is a small, independently runnable service built with the Microsoft Agent Framework, authenticated to Foundry with your Azure CLI login. Setup is deliberately boring: az login az account set --subscription "<your-subscription-id>" cp .env.example .env # Fill FOUNDRY_PROJECT_ENDPOINT and FOUNDRY_MODEL (e.g. gpt-5.1) # Create the employee-directory vector store once; note the printed VECTOR_STORE_ID python lesson-2-agent-development/setup_vector_store.py # Start an agent — serves on http://localhost:8090 python lesson-2-agent-development/employee-search-agent.py The FoundryChatClient auto-reads any FOUNDRY_ -prefixed environment variables and uses AzureCliCredential , so there are no keys in code. The lesson ships six samples, each on its own port, so you can chat with them individually in the local DevUI before wiring them together: Sample Tool Port employee-search-agent.py Foundry file search / vector store 8090 task-recommendation-agent.py GitHub MCP Server 8095 azure-learning-agent.py Microsoft Learn MCP 8092 coding-agent.py Code Interpreter 8093 learning-recommendation-agent.py Learn MCP + reasoning 8091 agent-orchestration.py Multi-agent handoff 8094 Why this matters: keeping each agent as its own process with its own port is a testability decision, not an accident. You can smoke-test one specialist in isolation, then compose them in agent-orchestration.py . Lesson 3 — Evaluation: you can't unit-test a probability distribution This is the lesson that separates a demo from a product. Agents are non-deterministic, so traditional assertions don't fit. The course uses three complementary layers: Observability / tracing — always on, via OpenTelemetry to Application Insights. Smoke tests — fast, run on every deploy. Evaluations — deeper, model-based scoring run on-demand or nightly. Turning on tracing is a single call: from agent_framework.foundry import FoundryChatClient client = FoundryChatClient() client.configure_azure_monitor() # export traces + metrics to Application Insights For quality it uses Foundry's built-in "LLM-as-a-judge" evaluators against real persisted responses (identified by response_id ), not freshly regenerated ones: Evaluator evaluator_name Measures Relevance builtin.relevance Does the response address the request? Groundedness builtin.groundedness Is it supported by retrieved data (no hallucination)? Tool-call accuracy builtin.tool_call_accuracy Were the right tools called with the right arguments? Tool-output utilization builtin.tool_output_utilization Did the agent actually use tool results? The judge model is set independently via AZURE_AI_MODEL_DEPLOYMENT_NAME , so you can evaluate a cheap production model with a stronger one. The run prints a report_url that deep-links into the Foundry portal. Lesson 4 — Deployment: a hosted agent, a UI, and a CI gate Now the agent becomes a managed service. It is deployed as a Foundry Hosted Agent a Microsoft-managed execution environment and fronted by an OpenAI ChatKit React UI talking to a FastAPI backend: ChatKit React (3000) → FastAPI backend (8001) → Foundry Hosted Agent → tools Building the agent is declarative attach tools, name it, serve it: agent = client.as_agent( name="DevOnboardingAgent", instructions="...", tools=[file_search_tool, learn_mcp_tool], ) # served with: from_agent_framework(agent).run() The recommended deploy path is the Azure Developer CLI: cd hosted-agent azd auth login azd agent deploy The genuinely production-minded part is the smoke test as a post-deploy CI gate. Six cases cover reachability, each scenario, off-topic prompt adherence, and multi-turn threading (verifying state via previous_response_id ). The GitHub Action runs them against the freshly deployed agent: export FOUNDRY_TOKEN=$(az account get-access-token \ --resource https://ai.azure.com/ --query accessToken -o tsv) python runner.py \ --project-endpoint "https://<account>.services.ai.azure.com/api/projects/<project>" \ --agent-name dev-onboarding \ --tests-file tests/smoke-tests.json Pitfall to remember: the token audience must be https://ai.azure.com/ . A cognitiveservices.azure.com token is rejected by the Responses API — a mistake that costs many engineers an afternoon. Lesson 5 — Production: separating where an agent runs from where its data lives The pivotal concept for enterprise readiness is the distinction between a Hosted Agent (compute, scaling, identity) and a Capability Host (where conversation history, files, and embeddings actually reside): Concern Hosted Agent Capability Host Compute / scaling / identity ✅ Provided — Conversation history Microsoft-managed default Redirect to your Azure Cosmos DB File uploads Microsoft-managed default Redirect to your Azure Storage Vector embeddings Microsoft-managed default Redirect to your Azure AI Search Required to run the agent? ✅ Yes ❌ Optional Required for data sovereignty? ❌ Not sufficient ✅ Yes "Basic" setup uses Microsoft-managed storage and is perfect for getting started. "Standard" setup redirects each data plane to your own Azure resources through a project-level capability host, this is how you keep customer data in your tenant, inside your network boundary: PUT .../accounts/{account}/projects/{project}/capabilityHosts/{name}?api-version=2025-06-01 { "properties": { "capabilityHostKind": "Agents", "threadStorageConnections": ["my-cosmosdb-connection"], "vectorStoreConnections": ["my-ai-search-connection"], "storageConnections": ["my-storage-connection"] } } Operational constraints worth internalising before you provision: there is one capability host per scope (a second attempt returns 409 Conflict ), configuration is immutable (delete and recreate to change it), deletion is destructive, and the account-level host must exist before the project-level one. Lesson 6 — Toolbox: govern tools once, reuse everywhere Left unchecked, every team re-implements the same tools, scatters credentials, and loses governance visibility. The Microsoft Foundry Toolbox solves this by exposing a curated, versioned set of tools behind a single MCP-compatible endpoint, with credentials held in Foundry connections rather than agent code. You build a toolbox version once: from azure.ai.projects.models import MCPTool, ToolboxSearchPreviewTool, WebSearchTool toolbox_version = project.toolboxes.create_toolbox_version( name="agent-tools", description="Web search + an MCP server + tool search", tools=[ WebSearchTool(), MCPTool( server_label="myserver", server_url="https://your-mcp-server.example.com", require_approval="never", project_connection_id="my-key-auth-connection", # credentials live in Foundry ), ToolboxSearchPreviewTool(), ], ) And every agent consumes it through one endpoint, no per-team tool code: from agent_framework import MCPStreamableHTTPTool mcp_tool = MCPStreamableHTTPTool( name="toolbox", url=TOOLBOX_ENDPOINT, # {project_endpoint}/toolboxes/{name}/mcp?api-version=v1 http_client=http_client, load_prompts=False, ) agent = chat_client.as_agent(name="my-toolbox-agent", instructions="...", tools=[mcp_tool]) Versioning is blue/green: create a new version, test it on its version-specific endpoint, then promote it to default and every consumer picks it up with zero code changes. A Guardrail (RAI) policy can be applied at the toolbox layer, independent of model-level content filters. Note the toolbox management APIs are currently preview; the portal or VS Code Foundry Toolkit are practical alternatives for creation today. Lesson 7 — Multi-Agent & A2A: agents as networked peers The final lesson contrasts two ways agents collaborate: Handoff / Workflow — in-process, same codebase, fastest, tightest coupling. Agent-to-Agent (A2A) — cross-process over an open protocol, so agents from different teams, orgs, or frameworks interoperate. A2A gives each agent a discoverable Agent Card at /.well-known/agent-card.json and a task lifecycle (submitted → working → completed/failed). The elegant part: A2AExecutor wraps an existing MAF agent with no changes to that agent's code. from agent_framework.a2a import A2AExecutor from a2a.server.apps import A2AStarletteApplication from a2a.server.tasks import InMemoryTaskStore agent_card = AgentCard( name="Coding Assistant", url="http://localhost:9000/", version="1.0.0", capabilities=AgentCapabilities(streaming=True), skills=[AgentSkill(id="generate-code", name="Generate code", tags=["code"])], ) request_handler = DefaultRequestHandler( agent_executor=A2AExecutor(agent), # wraps your existing MAF agent unchanged task_store=InMemoryTaskStore(), ) app = A2AStarletteApplication(agent_card=agent_card, http_handler=request_handler).build() Consuming a remote agent then looks exactly like calling a local one: from agent_framework.a2a import A2AAgent remote_agent = A2AAgent(name="remote-coding-assistant", url="http://localhost:9000") result = await remote_agent.run("Write a Python function that reverses a string.") Because an A2AAgent can be a participant inside a HandoffBuilder workflow, you can mix in-process routing with remote services in the same orchestration. For enterprise use, A2AAgent accepts an auth_interceptor for bearer tokens, and the Agent Card carries security_schemes . Responsible and secure by design Production readiness in this course is not just uptime, it is governance: Identity over keys — AzureCliCredential and managed identity throughout; no secrets in code. Least privilege — CI runners get a scoped Azure AI User role assignment on the specific project. Data sovereignty — capability hosts keep conversation history, files, and embeddings in your own Cosmos DB, Storage, and AI Search. Tool approval and guardrails — MCP approval_mode and toolbox-level RAI policy gate what agents can do. Grounded evaluation — groundedness and tool-utilization scoring catch hallucination and unused-tool behaviour before users do. Cost hygiene — the lessons create real Azure resources; delete the resource group when done: az group delete --name <rg> --yes --no-wait . Key takeaways Design as a graph of specialists. Handoff orchestration with tightly scoped agents beats one monolith on reliability and testability. One .run() contract, many backends. The Agent Framework keeps orchestration code stable from local dev to hosted production. Evaluate continuously. Tracing + smoke tests + model-based evaluators are three layers, not alternatives. Separate compute from data. Hosted Agents run the agent; Capability Hosts give you sovereignty — you need both for enterprise. Govern tools centrally. A versioned toolbox behind one MCP endpoint kills tool sprawl and credential duplication. Open protocols for interop. A2A lets agents cross team, org, and framework boundaries without rewrites.

From Multi-Model Chaos to a Governed AI Gateway: Cost Optimization on Azure
What is Multi-Model Chaos, and what cost and security challenges does it pose? Multi-model chaos describes the sprawl that emerges when an organization rapidly adopts many large language and foundation models—OpenAI, Anthropic, Meta Llama, Mistral, and a long tail of open-source and fine-tuned variants—across teams and applications without any unifying control plane. Instead of a single governed entry point, each team wires its own keys, endpoints, SDKs, and prompts directly to whichever provider it prefers, leaving the enterprise with a fragmented, duplicated, and largely invisible AI estate. On the cost side, this fragmentation makes spend almost impossible to predict or contain, identical workloads run against premium models when cheaper ones would suffice, token consumption goes unmeasured, redundant calls and missing caching inflate bills, and finance teams have no consolidated view to attribute usage back to a team, product, or customer. On the security and governance side, the risks compound: API keys are scattered across code and config files, sensitive or regulated data flows to external endpoints with no data-loss prevention or residency guarantees, prompt-injection and jailbreak attempts go unmonitored, and there is no centralized authentication, rate limiting, auditing, or content filtering. The net effect is an uncontrolled attack surface and a compliance blind spot—precisely the conditions that motivate consolidating model access behind a governed AI gateway. In short, multi-model chaos trades short-term speed for runaway costs and an unmanaged security risk, making a governed AI Gateway essential. What is a Governed AI Gateway, and how do they help reduce cost and improve security? A governed AI gateway is an enterprise control plane built on Azure API Management (APIM) that consolidates every model behind a single, governed endpoint. It unifies Azure OpenAI (the gpt-5.4 family) and Azure AI Foundry (open-source and partner models such as grok-4.3 and DeepSeek-V4-Pro), so consumers reach any of them through one consistent, policy-enforced entry point rather than a tangle of direct connections. Every backend is password-less, authenticated through managed identity, which eliminates scattered API keys. On top of this foundation, the gateway enforces per-consumer model permissions, token-based rate limits, and cost-based budget downgrade—automatically routing teams to more economical models as they approach their spend limits—all administered from a self-service Admin UI. One governed endpoint for every backend. Azure OpenAI and Azure AI Foundry (OSS and partner) models are bundled behind a single governance endpoint. Each backend is reachable only over a private endpoint with key authentication disabled, so APIM authenticates using its own managed identity—no model keys ever live on the gateway. Per-consumer governance, edited live in the Admin UI with no redeployment: Allowed models — a consumer can call only the models explicitly granted to it; anything else returns a 403. Rate limits — per-consumer TPM and token-quota tiers (small / medium / large), returning a 429 once exceeded. Cost budget — a daily USD spend limit; when it is exceeded, requests are automatically downgraded to a cheaper model along a configured ladder, including cross-backend downgrades (e.g. gpt → OSS or OSS → gpt). Self-service Admin UI (React + FastAPI, Entra ID login, gated to an admin group) to issue consumer keys, set model, limit, and budget policies, and review the usage dashboard and request logs. Built-in observability — per-call token metrics, broken down by consumer and model, stream to Application Insights, surfaced through the Admin UI's usage dashboard and a request / blocked & downgrade-event log. Flexible client authentication — an APIM subscription key by default, or an Entra ID JWT (client_auth_mode). How is it different from APIM AI Gateway? APIM already provides useful GenAI gateway primitives: token rate limiting, token-usage metrics, semantic caching, backend routing, endpoint import, authentication, authorization, and monitoring. The difference is that APIM enables the enforcement runtime and policy control point, but not the full operating model required to run a shared, multi-tenant AI platform across teams, models, and budgets. Inside the policy pipeline, APIM remains the load-bearing layer: llm-token-limit enforces per-consumer token-per-minute and quota limits, llm-emit-token-metric streams token usage into our metrics namespace, and standard APIM capabilities handle endpoint exposure, access control, and platform monitoring. The governed AI Gateway adds the governance layer APIM does not provide out of the box: Self-service onboarding — a platform team can issue or revoke consumer keys and manage access from the Admin UI, without raising a pull request or redeploying infrastructure. Per-consumer model entitlements — every consumer has an explicit allow-list of model deployments. The gateway calculates the effective allowed set per request and returns 403 when a caller asks for a model it is not entitled to use. Live configuration without redeployment — entitlements, rate tiers, token quotas, budgets, and downgrade levels live in the configuration store. A sync worker projects those values into APIM named values continuously, so operational changes can take effect without a terraform apply while the policy logic stays version-controlled in IaC. Managed-identity-only, private backends — key-based authentication is disabled on Azure OpenAI and Azure AI Foundry. APIM injects a managed identity token on every backend call, and the backends are reachable only over private endpoints. Cost-based downgrade across backends — when a consumer approaches its budget, the gateway can route to a cheaper model while preserving availability, including cross-backend downgrades between Azure OpenAI and Azure AI Foundry. APIM’s AI gateway is the enforcement runtime while the governed AI Gateway is the platform operating model around it. APIM handles the gateway primitives extremely well, while our governance layer adds identity, self-service administration, entitlement management, live configuration, cost controls, and cross-model routing so teams can safely consume multiple models without creating new cost, security, or compliance sprawl. Solution overview Figure 1 shows the end-to-end architecture of the governed AI gateway. Client applications never talk to the models directly; instead, every request passes through Azure API Management, which acts as the single governed entry point that authenticates callers, applies per-consumer policy, and routes traffic privately to the appropriate model backend. Around this gateway sit the supporting planes for administration, identity, and observability, giving the organization one consistent place to control access, contain cost, and monitor usage across both Azure OpenAI and Azure AI Foundry models. This solution is also completely serverless. Key components: Client / consumer applications — the apps and services that call for model inference, each identified by its own consumer key or Entra ID identity. Azure API Management (the gateway) — the single governance endpoint that handles authentication, allowed-model checks, rate limiting, and cost-based budget downgrade before any request reaches a model. Model backends — Azure OpenAI (the gpt-5.4 family) and Azure AI Foundry (OSS and partner models such as grok-4.3 and DeepSeek-V4-Pro), each reachable only over a private endpoint. Microsoft Entra ID — provides identity for both clients (optional JWT auth) and the gateway's own managed identity used to reach the backends without password credentials. Admin UI (React + FastAPI) — the self-service control plane for issuing consumer keys and setting model, rate-limit, and budget policies. Application Insights — collects per-call token metrics by consumer and model, powering the usage dashboard and request / blocked-event logs. 1: Solution architecture diagram Request flow Authenticate — a client calls the gateway with an APIM subscription key (or an Entra ID JWT) instead of any model key. Authorize the model — APIM checks whether the consumer is permitted to call the requested model; if not, it returns 403. Enforce limits — the gateway applies the consumer's TPM and token-quota tier, returning 429 when the limit is exceeded. Apply the cost budget — if the consumer's daily USD budget is exhausted, the request is automatically downgraded to a cheaper model along the configured ladder. Route to the backend — APIM forwards the request over a private endpoint, authenticating with its managed identity to Azure OpenAI or Azure AI Foundry. Return and record — the model response is returned to the client while per-call token metrics are emitted to Application Insights and surfaced in the Admin UI dashboard and logs. Implement the solution This section describes how to deploy the solution architecture. In this post, you’ll perform the following tasks: Create APIM Create Cosmos DB Create Microsoft foundry with Gpt-5.4, Gpt-5.4-mini, DeepSeek-V4-Pro and Grok-4.3 deployed Create the Admin UI on container apps Create a consumer with an APIM subscription key on the Admin UI Integrate APIM endpoint with Github Copilot chat and Copilot CLI Create a budget and rate limit in the Admin UI Simulate and validate auto downgrade feature Ensure that you have the following prerequisites deployed before moving to the next section An Azure subscription with model quota (Azure OpenAI and, optionally, Azure AI Foundry models). Tools: Git, Terraform ≥ 1.7, Azure CLI, and az login to the subscription. Container images are built remotely in Azure Container Registry, so Docker is not required. VScode and Copilot CLI Deploy the Azure AI Gateway Clone the repository from https://github.com/microsoft/apim-foundry-governance git clone https://github.com/microsoft/apim-foundry-governance git checkout english By default the solution deploys in koreacentral region. Export your custom variables if needed. export location=eastus2 export backend-rg=rg-aigw-tfstate-dev-eastus2 export storage-prefix=staigwtfstate export state-key=ai-gateway-eus2.tfstate Bootstrap the Terraform state backend (once per subscription) This creates an eastus2 resource group + storage account for remote state (Entra auth, public blob access blocked). ./scripts/bootstrap-backend.sh \ --location $location \ --backend-rg $backend-rg \ --storage-prefix $storage-prefix \ --state-key $state-key Set Terraform variables cp infra/terraform.tfvars.example infra/terraform.tfvars # Edit infra/terraform.tfvars: prefix, location, owner, cost_center, apim_publisher_*, budget_* Create the Gateway Core On the first apply, leave worker_image and admin_ui_image empty (default ""). The images don't exist yet, and the worker Job / Admin UI app are count-gated on these variables. cd infra terraform init # If you are moving an existing state from another backend, run `terraform init -migrate-state` instead. terraform apply Build and push the container images with app registrations After the registry is created, build the worker and Admin UI images remotely (no local Docker needed). acr=$(terraform output -raw registry_login_server) reg=$(terraform output -raw registry_name) az acr build --registry $reg --image config-sync-worker:latest ../app/config-sync-worker az acr build --registry $reg --image admin-ui:latest ../app/admin-ui The worker and Admin UI requires entra app registrations for a user to access the frontend. Create the admin security group, BFF API App registrations and SPA public-client app registrations. ./scripts/app-registration.sh Enable the worker and Admin UI From the output above, populate the image references and the three Entra variables from the prerequisites into infra/terraform.tfvars and apply again. worker_image = "<registry_login_server>/config-sync-worker:latest" admin_ui_image = "<registry_login_server>/admin-ui:latest" admin_ui_public = true # external FQDN (still Entra-gated). false = VNet-only admin_group_object_id = "<entra security group object id>" bff_api_audience = "api://<bff app id>" spa_client_id = "<spa app id>" entra_tenant_id = "<tenant id>" CosmosDB Seed configuration Cosmos is private with key auth disabled, so the initial config is seeded from a jumpbox inside the VNet. Default confguration of enable_jumpbox = true in infra/terraform.tfvars triggers Terraform to: provision the jumpbox VM, grant it’s managed identity the Cosmos DB Built-in Data Contributor role (scoped to the config container), and runs a VM run-command that seeds both documents automatically: Global config (id=global) — allowed models + token limits. Per-model pricing (id=pricing) — prompt/completion rates for cost-based budgeting. To seed manually instead (jumpbox connected via Bastion), the same scripts can be run directly: # Global allowed models + limits ./scripts/seed-cosmos-jumpbox.sh https://<cosmos-account>.documents.azure.com:443/ # Per-model pricing (for cost-based budgeting) ./scripts/seed-pricing-jumpbox.sh https://<cosmos-account>.documents.azure.com:443/ Access the AdminUI Update the SPA with your containerapps url spa_app_id="$(az ad app list --display-name "AI Gateway SPA" --query "[].appId" -o tsv)" # spa_client_id fqdn=$(terraform output -raw admin_ui_fqdn) # run from infra/ oid=$(az ad app show --id "$spa_app_id" --query id -o tsv) az rest --method PATCH \ --uri "https://graph.microsoft.com/v1.0/applications/$oid" \ --headers 'Content-Type=application/json' \ --body "{\"spa\":{\"redirectUris\":[\"https://$fqdn\"]}}" Browse to the admin_ui_fqdn, which is also the container apps fqdn. You will need to login via EntraID (Users will need to be added to the Entra group for them to login). Go ahead and register the consumer with a name and issue the API key. The API key is the APIM subscription key and will only be shown once on the UI, so copy and paste it somewhere safe. 2: AI Gateway Consumers and Keys Next, on the left hand tab, click on budgets. This will set the daily budget limit a user is allowed to consume in a day and is also where the model downgrade logic resides. For the purpose of demonstration, set a low budget of $1.8 and select the model priority that you want the downgrade to occur. In this case, gpt-5.4 will be used first, followed by gpt-5.4-mini, DeepSeek then Grok. 3: AI Gateway Budgets Lastly, on the land hand tab, select Rate limits. This sets the amount of tokens a user can consume in a day. It is a daily limit and resets after 24 hours. Select the large tier. 4: AI Gateway Rate Limits Browse to Dashboard, it shows you all the token information, request status codes and group them by consumer and model. You can also view the budget downgrade for a specific user. 5: AI Gateway Captions Integrate endpoint with github copilot chat in vscode In VScode, type “Ctrl + Shift + p” and select “Chat: Manage Language Model”. Select Add Models and choose Azure. 6: Add models toGithubCopilot Chat Follow through the prompts. It will create or edit a chatLanguageModels.json file. Your file should look like this. Take note that you will need to use the /vscode path. [ { "name": "Azure", "vendor": "azure", "models": [ { "id": "gpt-5.4", "name": "gpt-5.4 (APIM)", "url": "https://<REPLACE WITH YOUR APIM ENDPOINT>.azure-api.net/vscode/openai/deployments/gpt-5.4/chat/completions?api-version=2025-01-01-preview", "toolCalling": true, "vision": true, "maxInputTokens": 128000, "maxOutputTokens": 16000, "requestHeaders": { "Ocp-Apim-Subscription-Key": "<REPLACE WITH YOUR SUBSCRIPTION KEY" } } ] } ] Now select the gpt-5.4 (APIM) model and ask it a question. Integrate endpoint with copilot cli As copilot only accepts api-key headers, a separate api is used. Replace and export the following variables before using copilot cli. export COPILOT_PROVIDER_TYPE="azure" export COPILOT_PROVIDER_BASE_URL="<REPLACE WITH YOUR APIM ENDPOINT>" export COPILOT_PROVIDER_API_KEY="<REPLACE WITH YOUR SUBSCRIPTION KEY>" export COPILOT_MODEL="gpt-5.4" export COPILOT_PROVIDER_AZURE_API_VERSION="2025-01-01-preview" export COPILOT_PROVIDER_MODEL_ID="gpt-5.4" You should see a similar response. 7: Integration of APIM to copilot cli Simulate downgrade feature Continue to ask more questions to consume more tokens. Once it hits the 80% cost threshold, you should see that the tag has been switched to “Auto-switch level 1”, meaning it will downgrade to gpt-5.4-mini for future requests. 8: AI Gateway Downgrade Feature Validate by running this command in your terminal with your own endpoints and api-key. curl -sS -i -X POST "https://<REPLACE>.azure-api.net/openai/deployments/gpt-5.4/chat/completions?api-version=2025-01-01-preview" -H "api-key: <REPLACE WITH API KEY>" -H "Content-Type: application/json" -d '{"messages":[{"role":"user","content":"hi"}],"max_completion_tokens":8}' Inspect the headers, you should see that the downgrade level is 1 and the effective model is gpt-5.4-mini despite hitting the same endpoint of gpt-5.4. 9: Model downgrade Conclusion This post started with the problem of multi-model chaos: teams moving quickly with different models, endpoints, SDKs, keys, quotas, and cost profiles, but without a common control plane resulting in ineffective cost control and potential security leaks with model API keys. The governed AI Gateway addresses that by putting Azure OpenAI and Azure AI Foundry behind a single APIM-based entry point, where access, limits, routing, identity, telemetry, and budget behavior can be applied consistently for every consumer. We also walked through how the gateway is different from APIM’s native AI gateway capabilities. APIM provides the enforcement runtime and the GenAI policy primitives, such as token limits, token metrics, semantic caching, and backend routing. The governed AI Gateway builds the operating model around those primitives: self-service onboarding, per-consumer model entitlements, live configuration without redeployment, managed-identity-only private backends, per-call cost telemetry, and cost-based downgrade across model providers. From there, we integrated the APIM endpoint with Github Copilot Chat and Copilot CLI, and validated the downgrade behavior when spend thresholds were reached. The result is not just an AI proxy, but a reusable enterprise pattern for running AI access as a governed platform: developers keep a simple model endpoint experience, while the platform team keeps control over security, cost, observability, and operational change. Overall, this post helps organizations bring multi-model AI usage under one governed entry point, reducing sprawl across endpoints, keys, policies, and cost controls. It also gives platform teams centralized control over model access, rate limits, budgets, telemetry, and private backend access while preserving a simple endpoint experience for developers.

What if your development environment didn't just help you write code, but helped you observe, steer, and evolve a living system while it runs? That's the shift GitHub Copilot App Canvas represents. Canvas redefines how developers interact with agent-driven software: not by building traditional user interfaces, but by creating interactive environments where humans and AI co-create, test, and iterate in real time. This post walks through a real Canvas extension we built, a Multi-Agent Dev Canvas that demonstrates how Canvas becomes a runtime observability and control plane for an agent-driven system. We'll cover why Canvas exists, how it differs from traditional UI development, and how you can use it to accelerate the design-test-evolve loop for any multi-agent application. The Misconception: "Canvas Is for Building UIs" The first instinct many developers have when they see Canvas is to treat it like a UI framework, a place to build dashboards, boards, or user-facing applications. That's not what Canvas is for. Here's the distinction that matters: Traditional UIs are for using software. They serve end-users who interact with a finished product. Canvas is for shaping software while it runs. It serves developers and AI agents who are actively building, testing, and evolving a system. Canvas solves problems your final UI should never try to solve in a visible way. It's the observability layer, the control plane, the validation surface — all the things you need during development that disappear before production. Think of it this way: you wouldn't ship your debugger to users, but you absolutely need it while building. What We Built: A Multi-Agent Dev Canvas To demonstrate Canvas as a development runtime, we built a Multi-Agent Dev Canvas, a standalone GitHub Copilot Canvas extension (this repo, copilot-canvas-runtime) that treats an entire multi-agent system as a living, observable environment. The same pattern applies to any agent-driven system built on services such as Microsoft Foundry. The Multi-Agent Dev Canvas: a runtime observability and control plane where developers and AI agents collaborate to design, test, and evolve an agent-driven system in real time. The canvas provides four integrated panels: System View: See Your Agents Working Five specialised agents are displayed as live cards with real-time status indicators. Each card shows the agent's name, responsibility, current status (idle, running, done, or error), task count, and last action taken. When an agent is active, its card pulses blue. When it fails, it glows red. You see the system breathe. decompose_system — Breaks requirements into agent tasks execute_workflow — Coordinates agents to perform tasks validate_output — Runs evaluation tests and returns structured results update_system_design — Modifies architecture based on feedback track_state — Persists and updates system state over time Task Flows: Watch Work Move Through the Pipeline Below the agents, a flow graph visualises how tasks route between agents. When you decompose a system requirement like "Build an AI-powered code review agent," the canvas shows five components (pr-ingestion, code-analysis, feedback-generator, learning-loop, notification-service) flowing from the decomposer to the executor and designer agents. Each flow carries a status badge, pending, pass, or fail. Validation Panel: Continuous Testing, Not Afterthought Testing The validation panel displays structured test results with pass/fail badges and reasoning. When you run validation, each test case evaluates against specific criteria: ✅ "PR ingestion handles large diffs" — Meets criteria: process diffs over 5,000 lines without timeout ❌ "Feedback is actionable" — Failed: does not satisfy criteria that each suggestion includes a code fix ✅ "Learning loop converges" — Meets criteria: accept rate improves over 10 iterations ✅ "Notifications are non-blocking" — Meets criteria: delivery latency under 500ms This isn't a test runner you invoke separately, it's a validation surface embedded in the development loop. You see failures the moment they happen, in context, alongside the agents and flows that produced them. Live State Timeline: Every Mutation, Visible The right panel tracks every state change with timestamps. Decomposition events, workflow executions, validation runs, failure injections — all appear chronologically. This is the system's memory, visible to both the human developer and the AI agents working alongside them. Canvas as a Runtime: The Key Capabilities What makes Canvas a runtime rather than a display layer is that the agent can act through it. The canvas exposes seven agent-callable actions: Action What It Does decompose_system Accept requirements and components, generate task flows, update the system design execute_workflow Run pending tasks through the agent pipeline, produce artifacts validate_output Evaluate test cases against criteria, return structured pass/fail with reasoning update_system_design Modify the architecture description, constraints, or component list live track_state Read the full system state — agents, flows, validations, history, artifacts inject_failure Force an agent into an error state to test system adaptation pause_resume Toggle execution on and off The human developer can click Decompose, Execute, or Validate directly in the canvas. The AI agent can invoke the same actions programmatically. Both parties operate on the same surface, the same state, the same system, that's what makes Canvas collaborative in a way traditional tooling is not. Why This Matters: Canvas vs. Figma vs. Traditional UIs It helps to position Canvas against tools developers already know: Figma is Human-to-Human collaboration on design. Multiple people interact with the same visual surface, but nothing executes. It's a design tool. Traditional UIs are Human-to-System. Users interact with finished software through a polished interface. Canvas is Human-to-AI-to-System. It's a shared space where things actually execute. The developer steers, the AI acts, and the system evolves, all visible, all in real time. Canvas is collaborative in the Figma sense — it's a shared space, it's visual, multiple participants interact with the same surface. But unlike Figma, the participants include AI agents, and the surface isn't a mockup — it's a live system. How the Extension Works: Under the Hood A Canvas extension is a standard GitHub Copilot CLI extension, a single extension.mjs file that speaks JSON-RPC over stdio. The key components: 1. State Management Each canvas instance maintains its own system state: agents, task flows, validations, a state history timeline, artifacts, and the current system design. State is held in-memory per instance and pushed to the iframe via Server-Sent Events whenever it changes. function createInitialState() { return { agents: [ { id: "decomposer", name: "decompose_system", status: "idle", responsibility: "Break requirements into agent tasks" }, { id: "executor", name: "execute_workflow", status: "idle", responsibility: "Coordinate agents to perform tasks" }, // ... three more agents ], taskFlows: [], validations: [], stateHistory: [], artifacts: [], systemDesign: { description: "", constraints: [], components: [] }, execution: { paused: false, stepCount: 0 }, }; } 2. Real-Time Updates via Server-Sent Events The canvas runs a loopback HTTP server per instance. The iframe connects to an /events endpoint and receives state updates as they happen — no polling, no websocket complexity. if (req.url === "/events") { res.writeHead(200, { "Content-Type": "text/event-stream", "Cache-Control": "no-cache" }); clients.add(res); // Push current state immediately on connect res.write(`data: ${JSON.stringify(getState(instanceId))}\n\n`); } 3. Dual Interaction Model Every action is available through two paths. The human clicks a button in the iframe, which POSTs to the local server. The AI agent calls invoke_canvas_action through the SDK. Both paths mutate the same state and trigger the same SSE broadcast. Neither is privileged over the other. 4. Canvas Declaration The canvas registers with the Copilot SDK using createCanvas , declaring its identity, description, and all agent-callable actions with JSON Schema validation on inputs: createCanvas({ id: "multi-agent-dev", displayName: "Multi-Agent Dev Canvas", description: "Runtime observability and control plane for multi-agent development", actions: [ { name: "decompose_system", description: "Break requirements into agent tasks", inputSchema: { type: "object", properties: { requirements: { type: "string" }, components: { type: "array", items: { type: "string" } } }, required: ["requirements"] }, handler: async (ctx) => { /* ... */ }, }, // ... six more actions ], open: async (ctx) => { /* start server, return URL */ }, onClose: async (ctx) => { /* clean up */ }, }); Scenarios This Enables The Multi-Agent Dev Canvas supports four development scenarios that would be impossible with traditional tooling: 1. End-to-End Feature Design Tell the agent "Build an AI-powered code review system." Watch it decompose the requirement into five components, route tasks to specialist agents, execute the workflow, and validate the outputs, all visible in real time. Iterate by modifying constraints or components and re-running. 2. Live Agent Collaboration Observation See how agents hand off work to each other. The flow graph shows which agent produced what, which tasks are pending, and where bottlenecks form. This is the kind of observability you need when debugging multi-agent orchestration but would never expose in a production UI. 3. Fault Injection and Adaptation Testing Use inject_failure to force an agent into an error state. Watch how the system responds. Does the orchestrator recover? Do downstream tasks fail gracefully? This chaos-engineering approach, applied during development, visible in real time, catches integration failures before they reach production. 4. Validation-Driven Iteration Define test criteria, run validation, see which tests fail, update the system design, re-run. The validation panel isn't a separate CI pipeline, it's embedded in the development surface, creating a continuous feedback loop between design decisions and their measurable outcomes. Getting Started: Build Your Own Canvas Extension To create a Canvas extension in your own project: Read the SDK docs — Run extensions_manage({ operation: "guide" }) in GitHub Copilot CLI to get the canonical documentation paths. Scaffold — Run extensions_manage({ operation: "scaffold", kind: "canvas", name: "my-canvas", location: "project" }) to generate the boilerplate. Implement — Edit extension.mjs with your canvas logic: state model, actions, renderer HTML, and SSE updates. Reload — Run extensions_reload to activate your changes. Drive — Open with open_canvas , invoke actions with invoke_canvas_action , and iterate. The canvas extension lives in .github/extensions/your-canvas/extension.mjs for project-scoped extensions, or in your user extensions directory for personal use. No package.json needed, the github/copilot-sdk import is auto-resolved. Key Takeaways Canvas is a development runtime, not a UI framework. You don't build Canvas instead of your UI, you use Canvas to figure out, test, and evolve the UI and system before and during building it. Canvas solves problems your final UI should never expose. Agent observability, fault injection, live state mutation, validation feedback loops, these are development concerns, not user concerns. Canvas is Human-to-AI-to-System collaboration. Both the developer and the AI agent operate on the same surface, the same state, the same running system. It's Figma-like collaboration, but with AI agents, and things actually execute. Canvas turns debugging, testing, and execution into a continuous visual feedback loop. Instead of switching between an editor, a terminal, a test runner, and a monitoring dashboard, you have one surface where the system lives and evolves. Canvas extensions are lightweight. A single extension.mjs file, no dependencies, loopback HTTP server with SSE, the infrastructure gets out of the way so you can focus on the system you're building. The Bigger Picture Canvas redefines software development by shifting from writing static code to orchestrating living systems. Developers and AI co-create, observe, and evolve solutions in real time. Instead of building UIs for users, we build interactive environments for agents, turning debugging, testing, and execution into a continuous, visual feedback loop that accelerates innovation and brings ideas to production faster than ever. The Multi-Agent Dev Canvas we built here is one example. The pattern applies anywhere you're building agent-driven systems: AI orchestration, workflow automation, data pipelines, autonomous services. Anywhere you need to see, steer, and validate a complex system as it runs, that's where Canvas belongs.

If you have spent any time building with large language models in the last year, you have hit the same wall everyone hits: your model is brilliant at reasoning but blind to the real world. It cannot read your database, call your internal API, search your documents, or trigger a deployment unless you hand-write glue code for every single integration. The Model Context Protocol (MCP) exists to tear that wall down, and Microsoft's open-source MCP for Beginners curriculum (reachable via the short link https://aka.ms/mcp-for-beginners) is the most complete, hands-on way to learn it. This post explains what MCP is, walks through the latest updates to the course, shows real code, and makes the case for why MCP belongs on your learning roadmap right now. Whether you are an AI engineer shipping agents to production, a developer wiring tools into Copilot, or a student trying to build a standout portfolio project. What is MCP, and why does it matter? Think of MCP as a universal translator for AI applications. Just as a USB-C port lets you connect any peripheral to any laptop without a custom cable per device, MCP lets an AI model connect to any tool or data source through one standardized protocol. The course uses exactly this analogy, and it holds up well. Before MCP, integrations were an M × N problem: every one of your M AI applications needed bespoke code to talk to each of your N tools. MCP turns that into an M + N problem. Build a tool once as an MCP server, and any MCP-compatible client, Claude Desktop, VS Code, Cursor, GitHub Copilot, and many others — can use it immediately. The protocol is built on a clean client–server model with a small set of primitives: Tools — functions the model can call (query a database, send an email, run code). Resources — data the server exposes for context (files, records, documents). Prompts — reusable, parameterized prompt templates. Sampling — a server asking the client's LLM to generate a completion, enabling collaborative workflows. Elicitation — a server requesting structured input from the user mid-task. Roots — boundaries that tell a server which directories or resources it is allowed to operate on. Communication runs over JSON-RPC, with transports for local processes ( stdio ) and remote servers (streamable HTTP). That standardization is the whole point: write to the spec, and you interoperate with the entire ecosystem. What's new: the latest updates to the course The MCP for Beginners curriculum is actively maintained, and the public changelog reads like a release log for a living product. Here are the most important recent changes, drawn directly from that changelog. 1. Aligned to MCP Specification The biggest update: the entire curriculum has been validated against the current MCP Specification 2025-11-25 and the latest official SDKs. Stale references to older spec revisions (2025-03-26 and 2025-06-18) were corrected across the security, transport, real-time search, sampling, and stdio-server modules, with links repointed to the canonical modelcontextprotocol.io spec paths. A gap analysis confirmed the course already covers every primitive introduced or expanded in the latest spec: Sampling — covered in lesson 3.14 and Advanced Topics. Elicitation (including URL mode) — in Core Concepts and Protocol Features. Roots — in the Introduction, Core Concepts, and Root Contexts. Tasks (experimental, long-running operations) — in Core Concepts and Protocol Features. Tool Annotations ( readOnlyHint / destructiveHint ) — in Core Concepts and Protocol Features. 2. Samples validated against current SDKs Code that does not run is worse than no code at all, so the maintainers re-validated the core samples: TypeScript: @modelcontextprotocol/sdk resolved to 1.29.0 ; a tsc --noEmit type-check passed with no errors — the McpServer and StdioServerTransport APIs remain valid. Python: validated in an isolated virtual environment with mcp[cli] (1.27.2); FastMCP.list_tools() correctly returned the sample add and subtract tools. SDK version pins across labs were bumped (for example mcp>=1.26.0 ) and lockfiles regenerated so every sample tracks the current release. 3. A serious security pass Security is treated as a first-class concern, not an afterthought. A full audit across every dependency manifest and the sample source code was run, and npm audit now reports 0 vulnerabilities in every audited directory. Highlights: Transitive npm advisories (in the MCP Inspector dev tool, the OpenAI client, and the SDK) were remediated by bumping @modelcontextprotocol/inspector to 0.22.0 and pinning a patched shell-quote . A real code-level command-injection fix (OWASP A03): an open_in_vscode tool that used subprocess.run(..., shell=True) was rewritten to launch the resolved executable directly with no shell — closing a metacharacter-injection vector. Python dependencies were audited with pip-audit , and a vulnerable transitive werkzeug was pinned to a patched >=3.1.6 . For anyone learning to ship agents, this is gold: the course demonstrates the whole secure-development loop, not just the happy path. 4. New lessons and a growing curriculum The curriculum keeps expanding with practical, modern lessons: 5.17 Adversarial Multi-Agent Reasoning — two agents argue opposite sides of a question using shared MCP tools ( web_search + run_python ), judged by a third agent. Includes a Mermaid architecture diagram, orchestrators in Python, TypeScript, and C#, and use cases like hallucination detection, threat modeling, and API design review. 3.12 MCP Hosts — configuration for Claude Desktop, VS Code, Cursor, Cline, and Windsurf, with JSON templates and a transport comparison table. 3.13 MCP Inspector — a debugging guide for testing tools, resources, and prompts. 4.1 Pagination — cursor-based pagination patterns in Python, TypeScript, and Java. 5.16 Protocol Features — progress notifications, request cancellation, resource templates, and lifecycle management. 5. Microsoft product rebranding Content was updated to reflect Microsoft's rebranding: Azure AI Foundry → Microsoft Foundry, and the AI Toolkit (AITK) → Microsoft Foundry Toolkit Extension for VS Code. If you have seen older tutorials referencing the previous names, the curriculum is now current. Your first MCP server: see how little code it takes The course's "first server" lesson builds a simple calculator. Here is the shape of a minimal MCP server in Python using FastMCP , which mirrors the validated sample in the repo. Notice how the protocol plumbing disappears — you just decorate functions. # server.py — a minimal MCP server with two tools from mcp.server.fastmcp import FastMCP # Name your server; this identifies it to MCP clients mcp = FastMCP("Calculator") @mcp.tool() def add(a: int, b: int) -> int: """Add two numbers and return the result.""" return a + b @mcp.tool() def subtract(a: int, b: int) -> int: """Subtract b from a and return the result.""" return a - b if __name__ == "__main__": # Run over stdio so local hosts (VS Code, Claude Desktop) can connect mcp.run() The same idea in TypeScript, using the official SDK validated at version 1.29.0 : // server.ts — minimal MCP server in TypeScript import { McpServer } from "@modelcontextprotocol/sdk/server/mcp.js"; import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js"; import { z } from "zod"; const server = new McpServer({ name: "Calculator", version: "1.0.0" }); // Register a tool with a typed input schema server.tool( "add", { a: z.number(), b: z.number() }, async ({ a, b }) => ({ content: [{ type: "text", text: String(a + b) }], }) ); // Connect over stdio and start listening const transport = new StdioServerTransport(); await server.connect(transport); That is a complete, runnable server. The docstrings and schemas matter: MCP exposes them to the model so it knows when and how to call each tool. Clear descriptions are effectively prompt engineering for your tools — a common pitfall is leaving them vague, which leads to the model misusing or ignoring the tool. Connecting it in VS Code Once your server runs, an MCP host connects to it. A typical VS Code / host configuration looks like this: { "servers": { "calculator": { "command": "python", "args": ["server.py"] } } } Lesson 3.12 (MCP Hosts) covers the equivalent JSON for Claude Desktop, Cursor, Cline, and Windsurf, and lesson 3.13 shows how to use the MCP Inspector to test your tools before wiring them into a host — the single best debugging habit you can build early. How the course is structured The curriculum is organized as a progressive journey with hands-on code in C#, Java, JavaScript, Python, Rust, and TypeScript. It is grouped into phases: Foundations (Modules 0–2): Introduction, Core Concepts, and Security. Building (Module 3): Getting Started — 15 lessons covering your first server and client, LLM clients, VS Code integration, stdio and HTTP streaming, testing, deployment, auth, hosts, the Inspector, sampling, and MCP Apps. Growing (Modules 4–5): Practical Implementation and Advanced Topics — 17 advanced lessons including Azure integration, OAuth2, Entra ID auth, scaling, multi-modality, context engineering, custom transports, and adversarial multi-agent reasoning. Mastery (Modules 6–11): Community Contributions, Lessons from Early Adoption, Best Practices, Case Studies, a Microsoft Foundry Toolkit workshop, and an end-to-end 13-lab PostgreSQL capstone. That final module is the standout for portfolio building: a complete, production-flavored path that takes you from architecture and row-level security through database design, a FastMCP server, semantic search with pgvector and Azure OpenAI, testing, Docker deployment to Azure Container Apps, and monitoring with Application Insights. Why developers should learn MCP now For AI engineers MCP is becoming the default integration layer for agents. Instead of re-implementing tool calling for every framework, you write to one open protocol and your tools work everywhere. The advanced modules — sampling, roots, elicitation, scaling, routing, and adversarial multi-agent patterns — are exactly the techniques you need to move agents from demo to production. For developers MCP is already wired into tools you use daily: VS Code, GitHub Copilot, Claude Desktop, Cursor, and more. Learning to build an MCP server means you can expose your systems — internal APIs, databases, CI/CD — to AI assistants safely. The security-first approach in the course (OAuth2, Entra ID, RBAC, dependency auditing) teaches you to do this the right way from day one. For students MCP is a rare opportunity to learn a technology while it is still early, with a free, beginner-friendly, Microsoft-maintained curriculum and code in six languages. The 13-lab capstone alone is a genuine portfolio project. And with content translated into 50+ languages, the barrier to entry is low no matter where you are. Responsible and secure by design A recurring theme worth calling out: the course does not treat security and governance as optional extras. It models real practices you should carry into your own work: Least privilege via roots — constrain what a server can touch. Tool annotations — mark tools readOnlyHint or destructiveHint so clients can warn users before destructive actions. No shells for user input — the command-injection fix is a textbook example of why you never pass untrusted input through a shell. Dependency hygiene — audit with npm audit and pip-audit , and pin patched releases. Proper auth — dedicated lessons on OAuth2 and Microsoft Entra ID. Key takeaways MCP standardizes how AI connects to tools and data, turning a combinatorial integration problem into a simple, reusable one. The course is current, validated against MCP Specification 2025-11-25 with SDKs at TypeScript 1.29.0 and Python mcp 1.27.2 . Samples actually run, and the repo demonstrates a full secure-development loop with 0 reported vulnerabilities after auditing. It is broad and deep: from a 10-line calculator server to a 13-lab production capstone, in six languages. It is the fastest credible path to MCP fluency for AI engineers, developers, and students alike.
