Hello Microsoft Community Team, On June 26, 2026, our organization applied for a Microsoft 365 Developer Environment / Free Trial to support evaluation of the Microsoft Defender XDR Lab environment. To date, the environment has not been provisioned, and we have not received any status updates or confirmation. Impact: Current Status: We are currently utilizing our production environment to test project capabilities, which poses risks and limitations. Future Intent: Our organization plans to transition to a full, paid Business/Enterprise purchase immediately upon proving the platform’s benefits. Urgency: This delay is stalling our evaluation phase. We urgently need this environment onboarded and activated so we can proceed with deployment tests and subsequent procurement. Request: Please review the status of our registration and expedite the onboarding/provisioning of this developer environment. Thank you for your prompt assistance.
The new MD-102 and the missing labs
Hi. This complete rewrite of MD-102 has been long underway and very much wanted. The new courseware arrived on time, but much to our disappointment, we discovered that labs will first arrive in the next 30-60 days. Clients will not be happy with a 5 days course without labs. If this is the new norm, then it will render the Courseware Title Plan useless, if we only get part of the course on the dates mentioned.

Is it possible to check using the MPN Location ID or other details? Thank YouEnterprise-ready Claude Desktop with Entra ID, APIM, and Microsoft Foundry (No Backend Required)
How I put corporate sign-in in front of Claude Desktop without writing a single line of backend code. TL;DR — In this post, I show how to securely enable Claude Desktop in enterprise environments using Microsoft Entra ID, Azure API Management, and Microsoft Foundry — without deploying a custom backend. This approach removes API keys from endpoints, enforces per-user identity, and aligns fully with Zero Trust principles. Who this is for: Enterprise architects evaluating secure AI client patterns Developers enabling Claude Desktop in regulated environments Platform teams standardizing identity and governance for LLM access Why this post exists: Microsoft Learn's Configure Claude Desktop with Foundry Models only shows the API-key path — a shared key pasted into every user's Claude Desktop config. That's fine for a quick demo, but it's a non-starter for most enterprises (no per-user identity, no MFA / Conditional Access, hard to revoke, hard to audit). This post fills that gap: same Foundry backend, but with Microsoft Entra ID SSO in front via Azure API Management, so each user signs in with their corporate identity and zero secrets land on the laptop. The problem For many teams experimenting with Claude Desktop, the blocker isn't capability — it's enterprise readiness. How do you enforce identity, eliminate shared secrets, and apply governance without standing up a custom backend service to sit in front of the model? If your team wants to use Claude Desktop with your own Anthropic deployment running on Microsoft Foundry, but with a few non-negotiable requirements: No shared API keys floating around on developer laptops. Per-user identity — every request must be attributable to a real person. MFA and Conditional Access must apply, the same way they do for every other internal app. Central rate-limiting and logging — a centralized control plane for governance. Claude Desktop 1.5+ supports a "Gateway SSO" mode where it can sign each user in with OpenID Connect and forward their token to a custom LLM gateway. Azure API Management (APIM) is a perfect fit for that gateway role: it validates the user's Entra ID token, then re-authenticates itself to Foundry behind the scenes. APIM acts as a centralized policy enforcement layer, enabling identity validation, traffic governance, and secure re-authentication to backend AI services without custom code. The end-to-end flow looks like this: %%{init: {'flowchart': {'nodeSpacing': 60, 'rankSpacing': 80, 'useMaxWidth': true}, 'themeVariables': {'fontSize':'16px'}} }%% flowchart TB User([Corporate user]) Claude["Claude Desktop"] Entra["Microsoft Entra ID<br/>(OIDC + MFA + Conditional Access)"] APIM["Azure API Management<br/>validate-jwt → rewrite headers<br/>(policy gateway)"] Foundry["Microsoft Foundry<br/>Claude deployment"] User -- "1.

Foundry's key lives only inside APIM. And every request carries the user's oid claim, so I can build dashboards and per-user quotas later. What you need before starting An Azure subscription with a Microsoft Foundry (AI Services) account and a Claude deployment. (Throughout this post I'll just call it Foundry.) An API Management instance, any tier. Permission to register applications in Entra ID for your tenant. Claude Desktop 1.5.0 or later. Azure CLI installed locally. Throughout this post I'll use placeholders for resource names: <apim-name> — your API Management service name <resource-group> — the resource group that holds it <foundry-account> — your Foundry account name <deployment-name> — the name of the Claude model deployment on Foundry Step 1 — Register an Entra ID app for Claude Desktop This is the OIDC client Claude Desktop signs users into. Claude Desktop requires a single-tenant, public PKCE client (no client secret) with a loopback redirect URI, configured under the Mobile and desktop applications platform in Entra ID — the only platform that allows any loopback port. I scripted it so the setup is one command and idempotent: # scripts/register-claude-entra-app.ps1 [CmdletBinding()] param( [string] $TenantId = '<your-tenant-id>', [string] $SubscriptionId = '<your-subscription-id>', [string] $ResourceGroup = '<resource-group>', [string] $ApimName = '<apim-name>', [string] $AppDisplayName = 'Claude Cowork gateway', [string] $RedirectUri = 'http://127.0.0.1/callback' ) az account set --subscription $SubscriptionId | Out-Null # 1. Create (or reuse) the app registration $appId = az ad app list --display-name $AppDisplayName --query "[0].appId" -o tsv if (-not $appId) { $appId = az ad app create --display-name $AppDisplayName ` --sign-in-audience AzureADMyOrg --query appId -o tsv } # 2. Configure as public PKCE client with the Mobile/Desktop redirect URI $objectId = az ad app show --id $appId --query id -o tsv $patch = @{ publicClient = @{ redirectUris = @($RedirectUri) } isFallbackPublicClient = $true } | ConvertTo-Json -Depth 5 -Compress az rest --method PATCH ` --uri "https://graph.microsoft.com/v1.0/applications/$objectId" ` --headers "Content-Type=application/json" --body $patch | Out-Null # 3. Ensure a service principal exists $sp = az ad sp list --filter "appId eq '$appId'" --query "[0].id" -o tsv if (-not $sp) { az ad sp create --id $appId | Out-Null } # 4. Push two Named values into APIM for the validate-jwt policy az apim nv create -g $ResourceGroup --service-name $ApimName ` --named-value-id entra-tenant-id --display-name entra-tenant-id ` --value $TenantId --secret false az apim nv create -g $ResourceGroup --service-name $ApimName ` --named-value-id entra-client-id --display-name entra-client-id ` --value $appId --secret false "Client ID: $appId" Run it once. The output prints the client ID you'll need in Claude Desktop later, and it leaves two Named values in APIM ( entra-tenant-id , entra-client-id ) that the gateway policy will reference. ⚠️ Common pitfall: if the redirect URI ends up under the Web platform instead of Mobile and desktop applications, Entra will demand a client secret on token exchange — Claude won't send one and you'll get Token exchange failed (HTTP 401) . The app type can't be changed after creation, so create a new app if that happens. Step 2 — Create the API in APIM In the portal under APIM → APIs → + Add API → HTTP: Field Value Display name Anthropic API Name anthropicapi Web service URL https://<foundry-account>.services.ai.azure.com/anthropic API URL suffix claude Subscription required Off (Entra ID is our only credential) Add two operations under it: Method URL Display name POST /v1/messages Create message GET /v1/models List models The /v1/models operation isn't strictly needed (Foundry's Anthropic surface doesn't implement it), but having it registered means you can decide later whether to stub it out or proxy it. Step 3 — Add an API key for Foundry as a Named value APIM → Named values → + Add: Name: foundry-key Type: Secret Value: paste a key from the Foundry account's Keys and Endpoint blade. This is the only place the key ever lives. Clients never see it. Alternative — keyless with Entra ID (managed identity): If you prefer not to manage a Foundry key at all, enable the APIM instance's system-assigned managed identity (APIM → Identity → System assigned → On), then grant that identity the Foundry User role on the Foundry account (role ID 53ca6127-db72-4b80-b1b0-d745d6d5456d — previously named Azure AI User; Microsoft renamed it but the ID and permissions are unchanged). In Step 4, replace the set-header that injects x-api-key with: <authentication-managed-identity resource="https://cognitiveservices.azure.com" output-token-variable-name="foundry-token" /> <set-header name="Authorization" exists-action="override"> <value>@("Bearer " + (string)context.Variables["foundry-token"])</value> </set-header> Then you can skip the foundry-key Named value entirely. Don't use the legacy Cognitive Services User role — per the Foundry RBAC doc, roles starting with Cognitive Services don't apply to Foundry scenarios. Step 4 — Write the gateway policy This is the core enforcement layer in the architecture. Open APIs → anthropicapi → All operations → Inbound processing → </> and paste: <policies> <inbound> <base /> <!-- USER → APIM: verify Entra ID token from Claude Desktop --> <validate-jwt header-name="Authorization" failed-validation-httpcode="401" failed-validation-error-message="Unauthorized" require-scheme="Bearer"> <openid-config url="https://login.microsoftonline.com/{{entra-tenant-id}}/v2.0/.well-known/openid-configuration" /> <audiences> <audience>{{entra-client-id}}</audience> </audiences> <issuers> <issuer>https://login.microsoftonline.com/{{entra-tenant-id}}/v2.0</issuer> </issuers> </validate-jwt> <!-- APIM → Foundry --> <set-backend-service base-url="https://<foundry-account>.services.ai.azure.com/anthropic" /> <set-header name="x-api-key" exists-action="override"> <value>{{foundry-key}}</value> </set-header> <set-query-parameter name="api-version" exists-action="skip"> <value>2024-05-01-preview</value> </set-query-parameter> </inbound> <backend><base /></backend> <outbound><base /></outbound> <on-error><base /></on-error> </policies> Two things to notice: validate-jwt uses the OIDC discovery URL — JWKS keys are fetched and cached automatically. It rejects any token whose aud claim is not the client ID of our Entra app, which is exactly what we want. The Authorization header from the user is not forwarded — once validate-jwt succeeds, the request is re-authenticated to Foundry with x-api-key . No user token ever leaves APIM. APIM becomes the security boundary — user identity is validated at the edge, and downstream services never see or rely on user tokens. Step 5 — Configure Claude Desktop Open Claude Desktop → Configure third-party inference and fill it in like this: Field Value Connection Gateway Credential kind Interactive sign-in Gateway base URL https://<apim-name>.azure-api.net/claude Client ID (the appId your script printed) Issuer URL https://login.microsoftonline.com/<tenant-id>/v2.0 Authorization URL / Token URL leave empty Bearer token ID token (default) Scopes leave default ( openid profile email offline_access ) Redirect port leave empty (ephemeral) Model discovery Off Model list → Model ID <deployment-name> (your Foundry deployment name) ℹ️ Why Model discovery is Off — Claude Desktop's discovery uses GET /v1/models , and the Foundry /anthropic surface doesn't implement that endpoint, so it 404s. Listing the model manually skips the call entirely. If you want to leave Model discovery On, stub /v1/models in APIM. Add a GET /v1/models operation to your API and give it this inbound policy that returns an Anthropic-shaped response without ever hitting the backend: <policies> <inbound> <base /> <return-response> <set-status code="200" reason="OK" /> <set-header name="Content-Type" exists-action="override"> <value>application/json</value> </set-header> <set-body>@{ return new JObject( new JProperty("data", new JArray( new JObject( new JProperty("id", "<deployment-name>"), new JProperty("type", "model"), new JProperty("display_name", "Claude on Foundry"), new JProperty("created_at", "2026-01-01T00:00:00Z") ) )), new JProperty("has_more", false), new JProperty("first_id", "<deployment-name>"), new JProperty("last_id", "<deployment-name>") ).ToString(); }</set-body> </return-response> </inbound> <backend><base /></backend> <outbound><base /></outbound> <on-error><base /></on-error> </policies> Add one entry per deployment you want to expose. The benefit of stubbing rather than turning discovery off is that adding new models becomes a policy edit — no need to re-export and redeploy Claude Desktop config to every user. Click Apply Changes then Sign in to your organization. Your browser opens to the normal Entra sign-in page; once approved you're returned to the app, and a quick connection test runs. The success indicator is a small green banner: ✅ Inference — 1-token completion in 1449 ms · via identity provider For broader rollout, hit the Export button at the top of the configuration window — it produces a .mobileconfig (macOS) or .reg (Windows) you can push via Intune / Jamf to every user's machine. Step 6 — Verify both hops In APIM → APIs → anthropicapi → Test → POST /v1/messages I sent: Headers: anthropic-version: 2023-06-01 Body: { "model": "<deployment-name>", "max_tokens": 64, "messages": [{"role":"user","content":"hi"}] } Click Send → Trace, and look at two places: Inbound → validate-jwt: should say succeeded and show the decoded claims (your oid , email , etc.). Backend → Request: outbound URL is https://<foundry-account>.services.ai.azure.com/anthropic/v1/messages?api-version=2024-05-01-preview , with x-api-key: **** present and Authorization absent. Backend → Response: 200, with a Claude message JSON body. That confirms both halves of the chain. Bumps I hit along the way A few common issues encountered during setup — sharing so you can skip them: Symptom Cause Fix Claude shows "Your provider's model list hasn't loaded yet" and /v1/models returns 404 Foundry's Anthropic surface doesn't implement that endpoint Turn Model discovery OFF in Claude Desktop and add the deployment name manually Claude shows "Authentication failed" even though sign-in worked The APIM API still had Subscription required = ON, blocking the call before validate-jwt ran with 401: Access denied due to missing subscription key Uncheck Subscription required on the API Portal Test panel shows "Cannot read properties of undefined (reading 'statusCode')" The test console doesn't attach an Entra token, so validate-jwt 401s and the panel's JavaScript crashes Comment out <validate-jwt> temporarily for portal testing, or test via curl with a real token OIDC discovery failed (HTTP 404) in Claude Desktop Pasted the metadata URL into Issuer URL Issuer must end at /v2.0 , not at /.well-known/openid-configuration Token exchange failed (HTTP 401) App registered under Web platform instead of Mobile and desktop applications Create a new app with the right platform — it can't be changed Where this leaves us This pattern is small in moving parts but has outsized architectural impact: Zero secrets on endpoints. Eliminates API-key sprawl across laptops, MDM profiles, and shared vaults. The Foundry key lives only inside APIM — or disappears entirely when you switch APIM to managed identity. Identity, not credentials. Every Claude Desktop user authenticates against Entra ID in their browser, the same as Office or Teams. MFA, Conditional Access, and Entra ID Protection apply automatically — no parallel auth story to maintain. Per-user observability built in. APIM logs carry the user's Entra oid , email , and group claims. That unlocks per-user dashboards, cost allocation, and abuse detection without any client-side instrumentation. Aligned with Zero Trust. Strong identity at the edge, no implicit trust between hops, single policy chokepoint for inspection and rate-limiting, and full revocability through a single Enterprise Application. Optional but trivial keyless path. Flip APIM to system-assigned managed identity + <authentication-managed-identity resource="https://cognitiveservices.azure.com" /> and one Foundry User role assignment (role ID 53ca6127-db72-4b80-b1b0-d745d6d5456d , formerly Azure AI User) on the Foundry account. See the Foundry RBAC doc — don't use any Cognitive Services * roles for Foundry. What I'd add next llm-token-limit and llm-emit-token-metric policies for per-user quotas and cost visibility. App Insights wiring on the API, with a workbook that pivots on the oid claim. Assignment required = Yes on the Entra Enterprise Application + a security group, so only approved users can sign in. Intune deployment of the exported .reg / .mobileconfig so the gateway URL and client ID land on devices automatically. But that's all incremental. The hard part — getting Claude Desktop, Entra ID, APIM, and Foundry to agree on who's allowed to talk to whom — is done. Total elapsed: about an afternoon, most of it spent learning where each portal hides its switches.

There is a quiet shift happening in how we build software with AI. We are moving from writing static code to orchestrating living systems where developers and AI agents co-create, observe, and evolve a solution in real time. This post is a working theory of what GitHub Copilot App Canvas is actually for, grounded in a real, runnable demo you can clone today: leestott/agent-runtime-canvas. The Agent Runtime canvas open beside the chat — control bar, activity spotlight, requirement & constraints, and the live agent roster. The headline claim, which the rest of this post defends with code: Traditional UIs are for using software. Canvas is for shaping software while it runs. 1. The misconception worth getting out of the way The first instinct most engineers have when they see Canvas is to build a UI with it a dashboard, a DevOps board, an admin panel. That is the wrong mental model, and it leads to disappointment. A Kanban board rendered in Canvas is just a worse version of a tool that already exists. Canvas is not where your users live. It is where your system becomes visible to you and to the AI while you are still figuring it out. The distinction matters: You don't build Canvas instead of your UI. You use Canvas to figure out, test, and evolve the UI and the system before and during building it. Canvas solves problems your final UI should never try to solve in a visible way agent coordination, intermediate state, test validation, failure propagation. These are observability concerns, not end-user features. Canvas is intended for test validation and the implementation of agent-driven solutions not for shipping a production control panel. A useful analogy: Figma is Human-to-Human one person designs a static artifact for another person to read. Canvas is Human-to-AI-to-System a shared surface where a human, an AI agent, and a running system all act on the same live model. Figma shows you a picture of the software. Canvas is a runtime where things actually execute. 2. The positioning, stated plainly Here is the thesis the demo is built to prove: Canvas redefines software development by shifting from writing static code to orchestrating living systems, where 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. Read that again with the demo in mind, because the demo is not a slide, it is a working Copilot CLI extension that renders exactly this loop. 3. What we built: the Agent Runtime canvas agent-runtime-canvas is a GitHub Copilot CLI canvas extension called Agent Runtime. It turns Canvas into a runtime observability and control plane for a multi-agent software system that is being designed, tested, and evolved in real time. The canvas renders a single living SystemModel that both humans and the AI agent edit at the same time. The agent drives it through five canvas actions; the human drives it through panel controls. Every change streams to the iframe over Server-Sent Events (SSE), so the system visibly evolves through interaction. The seven panels: a system you can watch think Panel What it makes observable Requirement & constraints The feature under design plus editable policies and constraints Agents Active agents, their responsibilities, and live state (idle / working / done / error / blocked) Task Flow The dependency graph of tasks across agents, with live status Artifacts The intermediate outputs each task emits Validation Test cases, pass/fail, expected vs. actual, and the reasoning behind each verdict Live State The shared memory objects the agents read and write — directly human-editable Timeline A change-over-time log, including before→after state diffs None of these are things you would put in front of an end user. All of them are things you desperately want to see while you and an AI are co-designing an agentic system. The five agent actions The AI co-creates and evolves the system by calling five actions, declared in the canvas extension: Action Effect decompose_system Break a requirement into collaborating agents + a task-flow graph execute_workflow Coordinate agents to advance tasks ( step / run / pause / resume / reset ) validate_output Run evaluation tests, return structured pass/fail + reasoning update_system_design Modify architecture/logic: requirement, constraints, agents, tasks track_state Persist/update a shared state object, recording the diff on the timeline The critical detail is that human controls and agent actions funnel through the exact same store. There is no separate "AI view" and "human view" — one model, two kinds of participant. 4. How it actually works (the parts that matter) The extension is deliberately small and dependency-free. It uses only Node's built-in modules plus github/copilot-sdk , which the CLI auto-resolves. Three files do the work: .github/extensions/agent-runtime/ extension.mjs # wiring: loopback HTTP server, SSE, /control, 5 canvas actions store.mjs # durable SystemModel + execution engine + validation ui.mjs # iframe renderer (system view, validation, state, timeline) One shared model, broadcast on every mutation The heart of the demo is the SystemStore . It is an EventEmitter : every mutation bumps a version, appends a timeline entry, persists to disk, and broadcasts a fresh snapshot to all connected panels. This is the single line that makes "humans and AI edit the same live system" true rather than aspirational: // store.mjs — every change is versioned, logged, persisted, and broadcast. _commit(eventType, summary, detail) { this.model.version += 1; this.model.updatedAt = now(); if (eventType) { this.model.timeline.unshift({ id: uid("ev"), ts: now(), type: eventType, summary, detail: detail || null, }); this.model.timeline = this.model.timeline.slice(0, 200); } this._queueSave(); // best-effort JSON persistence under ~/.copilot this.emit("change", this.model); // fan out to every SSE client return this.model; } The agent action and the human button hit the same method In extension.mjs , the canvas action handler and the iframe's /control POST both call store.execute(...) . That symmetry is the whole point — neither the human nor the AI is privileged: // extension.mjs — a human control POST maps onto the same store method // the AI agent calls through the execute_workflow canvas action. function applyControl(store, body) { switch (body.action) { case "execute": return store.execute(body.mode || "step", body); case "validate": return store.validate(body.tests); case "decompose":return store.decompose(body.requirement, body); case "inject_failure": return store.injectFailure(body.taskKey); case "edit_state": return store.editState(body.key, body.value); // ...requirement, constraints, clear_failures, update_design } } Execution you can watch one task at a time The engine advances the task graph through a visible begin→dwell→finish lifecycle so the active agent is always observable. A ready task is one whose dependencies are all done : // store.mjs — the scheduler only starts a task when its deps are satisfied. _readyTask() { return this.model.tasks.find( (t) => t.status === "pending" && t.deps.every((d) => { const dep = this.model.tasks.find((x) => x.id === d); return dep && dep.status === "done"; }), ); } When a task finishes, its agent emits an artifact and writes to shared state; when a dependency fails, the engine walks the graph to a fixpoint and marks every downstream task blocked . That is failure propagation you can see — exactly the kind of thing a production UI would (correctly) hide, and exactly the kind of thing you need exposed while designing the system. Validation as a first-class, re-runnable citizen The default evaluation suite asserts properties of the running system, not of static code — every test returns an expected value, an actual value, and a human -readable reason: // store.mjs — tests assert properties of the live system model. _defaultTests() { const t = (name, target, assertion) => ({ id: uid("test"), name, target, assertion }); return [ t("All tasks reach a terminal state", "tasks", "no_pending"), t("No tasks failed", "tasks", "none_failed"), t("Every completed task emitted an artifact", "artifacts", "artifact_per_done"), t("Design state populated before build", "state", "design_before_build"), t("Decision recorded by Reviewer", "state", "has_decision"), ]; } This is the "continuous, visual feedback loop" from the thesis, made concrete: decompose → execute → validate → redesign → re-validate, with the Timeline recording every before→after transition. 5. Run it yourself You need a GitHub Copilot CLI / app with canvas support (the canvas-renderer capability) and this repo opened as your workspace. There is no npm install the SDK is auto-resolved and the extension uses only built-in Node modules. Clone and open the workspace. git clone https://github.com/leestott/agent-runtime-canvas.git cd agent-runtime-canvas The extension auto-discovers from .github/extensions/agent-runtime/ . Open the canvas with a requirement. Ask Copilot: Open the Agent Runtime canvas with the requirement "Add CSV export to the reports page". Walk the loop. Decompose into five agents and a six-task graph, press Run ▶, watch the spotlight track the active agent, press Run tests ✓ for 5/5 green, then Inject failure ⚡ to watch downstream tasks go blocked and validation drop to 4/5 — and recover. State persists per documentId under ~/.copilot/extensions/agent-runtime/artifacts/ , so a reload resumes exactly where you left off. The companion demoscript.md in the repo gives you a tight, timed walkthrough. 6. Why this is an observability story Once you accept that Canvas is a runtime rather than a UI, the most compelling use case becomes observability of agentic systems. Agentic software is notoriously hard to debug: the interesting behavior lives in intermediate state, coordination order, and the moments where one agent's failure cascades into another's. A production UI is designed to hide all of that. A Canvas is designed to surface it, temporarily, while you are shaping the system — and then get out of the way. This reframes Canvas alongside the broader Microsoft and GitHub agent tooling story. As teams adopt the GitHub Copilot SDK and patterns like the open Model Context Protocol to wire agents into real systems, the gap is rarely "can the agent act?" it is "can a human see what the agent did, judge it, and steer it?" Canvas is a candidate answer to that second question. When you take agents toward production on Azure with services like Microsoft Foundry, the same instinct applies: build the evaluation and observability loop first, and let it shape the system before you commit a single end-user pixel. 7. The open question: why can't Canvas be multi-user? There is an obvious next frontier, and it is worth stating as an honest open question rather than a finished feature. Everything that makes Canvas valuable also makes it a natural collaborative surface: It is a shared space. It is visual. It is collaborative. Multiple participants — human and AI — interact with the same surface. If Figma earned its place by making Human-to-Human design multiplayer, the provocative question is whether a project- or repo-scoped Canvas can make Human-to-AI-to-System development multiplayer too: several engineers and several agents shaping one running system on one surface. The demo here is single-user by design, but its architecture — one shared store, versioned, broadcast to every subscriber — is already the shape you would need. That is a genuine research direction, and worth experimenting with as licensing and access broaden. 8. Honest limitations In the spirit of building credibility rather than hype: This is a demonstration. The decomposition, artifacts, and state are synthesized to make the runtime loop legible — it models an agentic system rather than running arbitrary production agents. It is single-user and single-machine. The loopback HTTP server and per-document store are local by design; multi-user is an aspiration, not a shipped capability. Access is gated. Canvas support requires a Copilot CLI/app build with the canvas-renderer capability. Licensing and preview access are the biggest practical blockers to wider experimentation today. Persistence is best-effort. State is written to a local JSON artifact; treat it as demo durability, not a database. Key takeaways Don't build a UI in Canvas. Use Canvas to shape, test, and evolve a system — and the UI — while it runs. Traditional UIs are for using software; Canvas is for shaping software while it runs. Canvas is Human-to-AI-to-System, a runtime where things execute — not a static design surface. Its strongest use case is observability and validation of agentic systems: surface the intermediate state your production UI should hide. The shared-model architecture — one versioned store broadcast to every participant — is what makes human + AI co-editing real, and what hints at a multi-user future. Next steps Clone and run the demo: github.com/leestott/agent-runtime-canvas. Read the extension source under .github/extensions/agent-runtime/ — start with store.mjs . Explore the building blocks: the GitHub Copilot SDK, the Model Context Protocol, and Microsoft Foundry for taking agentic systems toward production. Try the multi-user thought experiment: fork the store, add a second subscriber, and ask what changes when two humans and two agents share one surface.Master the Command Line with GitHub Copilot CLI:
If you are a student aiming to become an AI engineer or a software developer, the terminal is about to become your most powerful classroom. https://github.com/features/copilot/cli/ brings an AI agent directly into your command line, and its slash commands (typed as /something ) are the shortcuts that unlock its real capabilities. The problem most students hit is simple: they install a powerful tool and then only ever use 10% of it. They type questions, get answers, and never discover the commands that turn Copilot CLI from a chatbot into a genuine pair programmer. This post fixes that. We will walk through the most useful slash commands, explain why you would reach for each one, and give you concrete student scenarios for every command. Why This Matters Now AI-assisted development is no longer optional in the industry. Employers increasingly expect graduates to be fluent with AI developer tools, not just programming languages. Learning the Copilot CLI slash commands early gives you two advantages: Speed: You spend less time context-switching between docs, terminal, and editor. Good habits: Commands like code review and security review teach you professional workflows while you are still learning. Everything below is grounded in the actual command set shipped in Copilot CLI. To see the full, current list at any time, just type /help inside the CLI. How to Run a Slash Command Slash commands are typed at the Copilot CLI prompt. Start a command with a forward slash and the CLI shows you an autocomplete menu: # Launch the CLI copilot # Then, at the prompt, type a slash to browse commands / # Or jump straight to one /model /plan /review A few related shortcuts are worth memorising on day one: ? — show quick help @ — mention files so Copilot reads them # — mention GitHub issues and pull requests ! — execute a raw shell command without leaving the prompt The Most Useful Slash Commands for Students The table below groups the highest-value commands by the job you are trying to do. Each row includes a realistic student scenario so you know exactly when to reach for it. Learning and Planning Command What it does Student scenario: why use it /plan Creates an implementation plan before any code is written. You have a coursework project ("build a sentiment classifier") but no idea where to start. Run /plan to get a step-by-step roadmap you can follow and learn from, instead of diving in blind. /research Runs a deep research investigation using GitHub search and web sources. For a dissertation or capstone, you need to compare approaches (e.g. "vector databases for RAG"). Use /research to gather grounded, cited findings rather than guessing. /ask Asks a quick side question without adding it to the conversation history. Mid-project you forget what a Python decorator does. Ask with /ask so your main task context stays clean and focused. /model Selects which AI model to use (or auto to let Copilot pick). A simple formatting fix needs a fast model; a tricky algorithm needs a stronger one. Learn to match the model to the task — a real engineering skill. Writing and Reviewing Code Command What it does Student scenario: why use it /diff Reviews the changes made in the current directory. Before submitting an assignment, run /diff to see exactly what changed — catch that debug print() you forgot to remove. /review Runs a code review agent to analyse your changes. No teaching assistant available at 2am? /review gives you professional-style feedback on bugs and logic errors so you learn before the deadline, not after grading. /security-review Analyses staged and unstaged changes for security vulnerabilities. Building a web app for a module? Run /security-review to spot issues like injection flaws — and start building the security mindset employers want. /pr Operates on pull requests for the current branch. Contributing to a group project or open source? Use /pr to manage pull requests and learn the collaboration workflow used in every real engineering team. /ide Connects Copilot to an IDE workspace. You prefer working in VS Code. Connect with /ide so Copilot understands your open files and editor context. Managing Your Work Session Command What it does Student scenario: why use it /resume Switches to a different saved session. You worked on a lab yesterday and want to continue today. /resume brings back the full context instead of starting from scratch. /context Shows context-window token usage and a visualization. Copilot seems to be "forgetting" earlier details. Check /context to understand how much conversation history fits — a core concept for any aspiring AI engineer. /compact Summarises conversation history to reduce context usage. Long debugging session running out of context? /compact condenses it so you can keep going without losing the thread. /undo / /rewind Rewinds the last turn and reverts file changes. Copilot made an edit that broke your tests. /undo safely rolls it back so you can experiment fearlessly. /usage Displays session usage metrics and statistics. Curious how much you are relying on the AI? /usage helps you stay aware of your consumption and learning balance. Setting Up and Extending the Environment Command What it does Student scenario: why use it /init Initialises Copilot instructions for the current repository. Starting a new project repo? /init sets up custom instructions so Copilot follows your project's conventions consistently. /mcp Manages Model Context Protocol (MCP) server configuration. Want Copilot to query a database or external tool? /mcp connects MCP servers — a cutting-edge skill for AI engineering portfolios. /agent Browses and selects specialised agents. Different tasks suit different agents. /agent lets you pick the right specialist for the job. /memory Shows memory status, or enables/disables memory across sessions. Want Copilot to remember your preferences (e.g. "I use Python type hints")? Manage that with /memory . A Realistic Student Workflow, End to End Here is how these commands fit together for a typical assignment — building a small machine learning script. Notice how the commands chain into a professional development loop: # 1. Plan the work before touching code /plan # 2. Pick an appropriate model for the task /model # 3. Let Copilot reference your data file @data/train.csv # 4. After Copilot writes code, see what changed /diff # 5. Get an automated code review /review # 6. Check for security issues before you submit /security-review # 7. If an edit broke something, roll it back /undo This loop —> plan, build, review, secure, iterate, is exactly the cycle used by professional engineering teams. By practising it now with Copilot CLI, you are rehearsing the workflow you will use in your first job. Responsible Use: Learn With AI, Not Instead Of It A quick but important note for students. AI assistance is a learning accelerator, not a replacement for understanding. Keep these principles in mind: Read the explanations, not just the code. Use /ask and /review to understand why something works. Check your institution's policy. Many courses have rules about AI use in assessed work, make sure you comply and cite appropriately. Never paste secrets. Keep API keys, passwords, and personal data out of prompts. Verify before you trust. Run the code, read the security review, and confirm claims against official documentation. Key Takeaways Slash commands turn Copilot CLI from a Q&A box into a full development partner. Start with /plan , /diff , /review , and /security-review they build professional habits immediately. Use /model , /context , and /compact to understand how AI systems actually work under the hood. Type /help any time to see the complete, current command list for your version. Next Steps and Resources Read the official guide: Use GitHub Copilot CLI Explore the broader docs: GitHub Copilot documentation Open the CLI and run /help to browse every command interactively. Pick one assignment this week and run the full plan → review → security-review loop on it. The fastest way to learn is to try. Launch Copilot CLI, type a single / , and start exploring. Your future engineering self will thank you.MCP for Beginners: Why Every AI Engineer and Developer Should Learn the Model Context Protocol
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.
