Durable Task Extension for Microsoft Agent Framework で、堅牢なエージェントを構築する
（これは 2025/11/13 に出された製品チームの記事『Bulletproof agents with the durable task extension for Microsoft Agent Framework』を日本語に翻訳したものです。） 本日 (2025/11/13)、Durable Task Extension for Microsoft Agent Framework のパブリックプレビューを発表できることを大変うれしく思います。 この拡張機能は、Azure Durable Functions の 実績ある 耐久性のある実行 (durable execution) (クラッシュや再起動に耐える) と分散実行 (複数インスタンスで動作する) 機能を、Microsoft Agent Framework に直接組み込むことで、本番環境対応の、堅牢でスケーラブルな AI エージェントの構築方法を一新します。 これにより、セッション管理、障害復旧、スケーリングを自動的に処理する、ステートフルで堅牢な AI エージェントを Azure にデプロイでき、開発者はエージェントのロジックに完全に集中できるようになります。 たとえば、複数日にわたる会話でコンテキストを維持するカスタマーサービスエージェント、人間による承認 (human-in-the-loop approval workflow) を含むコンテンツパイプライン、または専門的な AI モデルを連携させる完全自動化されたマルチエージェントシステムを構築する場合でも、この Durable Task Extension for Microsoft Agent Framework は、サーバーレスのシンプルさで本番レベルの信頼性、スケーラビリティ、そして調整機能を提供します。 Durable Task Extension の主な機能： サーバーレスホスティング (Serverless Hosting)：Azure Functions 上にエージェントをデプロイし、数千のインスタンスからゼロまで自動スケーリングを実現しながら、サーバーレスアーキテクチャの利点を維持したまま完全な制御を保持します。 自動セッション管理 (Automatic Session Management)：エージェントは、プロセスのクラッシュや再起動、インスタンス間の分散実行に耐える、完全な会話コンテキストを保持した永続的なセッションを維持します。 決定的なマルチエージェントオーケストレーション (Deterministic Multi-Agent Orchestrations)： コードで制御された、予測可能かつ再現性のある実行パターンで、特化した (specialized) durable agents を組み合わせて動作させる。 (訳註１：「決定的な (deterministic)」とは、同じ入力に対しては常に同じ結果を返すもので、その動作が予測可能なものを指します) (訳註２：「durable agent」とは、このフレームワークのエージェントをそう呼んでおり、普通のエージェントと違ってDurable な性質を持っているエージェントのことを指します) サーバーレスによるコスト削減を伴う Human-in-the-Loop (Human-in-the-Loop with Serverless Cost Savings)： 人間の入力を待つ間、コンピュートリソースを消費せず、コストも発生しません。 Durable Task Scheduler による組み込みの可観測性 (Built-in Observability with Durable Task Scheduler)：Durable Task Scheduler の UI ダッシュボードを通じて、エージェントの操作やオーケストレーションを深く可視化できます。 Durable Agent を作成して実行してみる 公式ドキュメント https://aka.ms/create-and-run-durable-agent コードサンプル (Python/C#) # Python endpoint = os.getenv("AZURE_OPENAI_ENDPOINT") deployment_name = os.getenv("AZURE_OPENAI_DEPLOYMENT_NAME", "gpt-4o-mini") # 標準的な Microsoft Agent Framework パターンに従って AI エージェントを作成します agent = AzureOpenAIChatClient( endpoint=endpoint, deployment_name=deployment_name, credential=AzureCliCredential() ).create_agent( instructions="""あなたは、どんなテーマに対しても読みやすく構造化された、 魅力的なドキュメントを作成するプロフェッショナルなコンテンツライターです。 テーマが与えられたら、次の手順で進めてください。 1.

Durable なセッション管理でエージェントをホストするように Function アプリを構成します app = AgentFunctionApp(agents=[agent]) app.run() Automatic session management（自動セッション管理） エージェントのセッションは、Function アプリで構成した耐久性のあるストレージに自動的にチェックポイントされ、複数インスタンス間での耐久性と分散実行を可能にします。中断やプロセス障害の後でも、どのインスタンスからでもエージェントの実行を再開でき、継続的な運用が保証されます。 内部的には、エージェントは Durable Entities として実装されています。これらは、実行間で状態を保持するステートフルなオブジェクトです。このアーキテクチャにより、各エージェントセッションは、会話履歴とコンテキストを保持した信頼性の高い長寿命のエンティティとして機能します。 シナリオ例: 複数日から数週間にわたる複雑なサポート案件を処理するカスタマーサービスエージェント。エージェントが再デプロイされたり、別のインスタンスに移動した場合でも、会話履歴、コンテキスト、進捗は保持されます。 #

AI agents that can actually do stuff (not just chat) are the fun part nowadays, but wiring them cleanly into real APIs, keeping things observable, and shipping them to the cloud can get... messy. So we built a fresh end‑to‑end sample to show how to do it right with the brand new LangChain.js v1 and Model Context Protocol (MCP). In case you missed it, MCP is a recent open standard that makes it easy for LLM agents to consume tools and APIs, and LangChain.js, a great framework for building GenAI apps and agents, has first-class support for it. You can quickly get up speed with the MCP for Beginners course and AI Agents for Beginners course. This new sample gives you: A LangChain.js v1 agent that streams its result, along reasoning + tool steps An MCP server exposing real tools (burger menu + ordering) from a business API A web interface with authentication, sessions history, and a debug panel (for developers) A production-ready multi-service architecture Serverless deployment on Azure in one command ( azd up ) Yes, it’s a burger ordering system. Who doesn't like burgers? Grab your favorite beverage ☕, and let’s dive in for a quick tour! TL;DR key takeaways New sample: full-stack Node.js AI agent using LangChain.js v1 + MCP tools Architecture: web app → agent API → MCP server → burger API Runs locally with a single npm start , deploys with azd up Uses streaming (NDJSON) with intermediate tool + LLM steps surfaced to the UI Ready to fork, extend, and plug into your own domain / tools What will you learn here? What this sample is about and its high-level architecture What LangChain.js v1 brings to the table for agents How to deploy and run the sample How MCP tools can expose real-world APIs Reference links for everything we use GitHub repo LangChain.js docs Model Context Protocol Azure Developer CLI MCP Inspector Use case You want an AI assistant that can take a natural language request like “Order two spicy burgers and show me my pending orders” and: Understand intent (query menu, then place order) Call the right MCP tools in sequence, calling in turn the necessary APIs Stream progress (LLM tokens + tool steps) Return a clean final answer Swap “burgers” for “inventory”, “bookings”, “support tickets”, or “IoT devices” and you’ve got a reusable pattern! Sample overview Before we play a bit with the sample, let's have a look at the main services implemented here: Service Role Tech Agent Web App ( agent-webapp ) Chat UI + streaming + session history Azure Static Web Apps, Lit web components Agent API ( agent-api ) LangChain.js v1 agent orchestration + auth + history Azure Functions, Node.js Burger MCP Server ( burger-mcp ) Exposes burger API as tools over MCP (Streamable HTTP + SSE) Azure Functions, Express, MCP SDK Burger API ( burger-api ) Business logic: burgers, toppings, orders lifecycle Azure Functions, Cosmos DB Here's a simplified view of how they interact: There are also other supporting components like databases and storage not shown here for clarity. For this quickstart we'll only interact with the Agent Web App and the Burger MCP Server, as they are the main stars of the show here. LangChain.js v1 agent features The recent release of LangChain.js v1 is a huge milestone for the JavaScript AI community! It marks a significant shift from experimental tools to a production-ready framework. The new version doubles down on what’s needed to build robust AI applications, with a strong focus on agents. This includes first-class support for streaming not just the final output, but also intermediate steps like tool calls and agent reasoning. This makes building transparent and interactive agent experiences (like the one in this sample) much more straightforward. Quickstart Requirements GitHub account Azure account (free signup, or if you're a student, get free credits here) Azure Developer CLI Deploy and run the sample We'll use GitHub Codespaces for a quick zero-install setup here, but if you prefer to run it locally, check the README. Click on the following link or open it in a new tab to launch a Codespace: Create Codespace This will open a VS Code environment in your browser with the repo already cloned and all the tools installed and ready to go. Provision and deploy to Azure Open a terminal and run these commands: # Install dependencies npm install # Login to Azure azd auth login # Provision and deploy all resources azd up Follow the prompts to select your Azure subscription and region. If you're unsure of which one to pick, choose East US 2 . The deployment will take about 15 minutes the first time, to create all the necessary resources (Functions, Static Web Apps, Cosmos DB, AI Models). If you're curious about what happens under the hood, you can take a look at the main.bicep file in the infra folder, which defines the infrastructure as code for this sample. Test the MCP server While the deployment is running, you can run the MCP server and API locally (even in Codespaces) to see how it works. Open another terminal and run: npm start This will start all services locally, including the Burger API and the MCP server, which will be available at http://localhost:3000/mcp . This may take a few seconds, wait until you see this message in the terminal: 🚀 All services ready 🚀 When these services are running without Azure resources provisioned, they will use in-memory data instead of Cosmos DB so you can experiment freely with the API and MCP server, though the agent won't be functional as it requires a LLM resource. MCP tools The MCP server exposes the following tools, which the agent can use to interact with the burger ordering system: Tool Name Description get_burgers Get a list of all burgers in the menu get_burger_by_id Get a specific burger by its ID get_toppings Get a list of all toppings in the menu get_topping_by_id Get a specific topping by its ID get_topping_categories Get a list of all topping categories get_orders Get a list of all orders in the system get_order_by_id Get a specific order by its ID place_order Place a new order with burgers (requires userId , optional nickname ) delete_order_by_id Cancel an order if it has not yet been started (status must be pending , requires userId ) You can test these tools using the MCP Inspector. Open another terminal and run: npx -y @modelcontextprotocol/inspector Then open the URL printed in the terminal in your browser and connect using these settings: Transport: Streamable HTTP URL: http://localhost:3000/mcp Connection Type: Via Proxy (should be default) Click on Connect, then try listing the tools first, and run get_burgers tool to get the menu info. Test the Agent Web App After the deployment is completed, you can run the command npm run env to print the URLs of the deployed services. Open the Agent Web App URL in your browser (it should look like https://<your-web-app>.azurestaticapps.net ). You'll first be greeted by an authentication page, you can sign in either with your GitHub or Microsoft account and then you should be able to access the chat interface. From there, you can start asking any question or use one of the suggested prompts, for example try asking: Recommend me an extra spicy burger . As the agent processes your request, you'll see the response streaming in real-time, along with the intermediate steps and tool calls. Once the response is complete, you can also unfold the debug panel to see the full reasoning chain and the tools that were invoked: Tip: Our agent service also sends detailed tracing data using OpenTelemetry. You can explore these either in Azure Monitor for the deployed service, or locally using an OpenTelemetry collector. We'll cover this in more detail in a future post. Wrap it up Congratulations, you just finished spinning up a full-stack serverless AI agent using LangChain.js v1, MCP tools, and Azure’s serverless platform. Now it's your turn to dive in the code and extend it for your use cases! 😎 And don't forget to azd down once you're done to avoid any unwanted costs. Going further This was just a quick introduction to this sample, and you can expect more in-depth posts and tutorials soon. Since we're in the era of AI agents, we've also made sure that this sample can be explored and extended easily with code agents like GitHub Copilot. We even built a custom chat mode to help you discover and understand the codebase faster! Check out the Copilot setup guide in the repo to get started. You can quickly get up speed with the MCP for Beginners course and AI Agents for Beginners course. If you like this sample, don't forget to star the repo ⭐️!

Modern systems must be modular and interoperable by design. Integration is no longer a feature, it’s a requirement. Developers are expected to build architectures that connect easily with third-party platforms, but too often, core systems are designed in isolation. This disconnect creates friction for downstream teams and slows delivery. At Microsoft, SaaS platforms like SAP SuccessFactors and Eightfold support Talent Acquisition by handling functions such as requisition tracking, application workflows, and interview coordination. These tools help reduce costs and free up engineering focus for high-priority areas like Azure and AI. The real challenge is integrating them with internal systems such as Demand Planning, Offer Management, and Employee Central. This blog post outlines a strategy centered around two foundational components: an Integration and Orchestration Layer, and a Messaging Platform. Together, these enable real-time communication, consistent data models, and scalable integration. While Talent Acquisition is the use case here, the architectural patterns apply broadly across domains. Whether you're embedding AI pipelines, managing edge deployments, or building platform services, thoughtful integration needs to be built into the foundation, not bolted on later.Introducing Azure AI Travel Agents: A Flagship MCP-Powered Sample for AI Travel Solutions
We are excited to introduce AI Travel Agents, a sample application with enterprise functionality that demonstrates how developers can coordinate multiple AI agents (written in multiple languages) to explore travel planning scenarios. It's built with LlamaIndex.TS for agent orchestration, Model Context Protocol (MCP) for structured tool interactions, and Azure Container Apps for scalable deployment. TL;DR: Experience the power of MCP and Azure Container Apps with The AI Travel Agents! Try out live demo locally on your computer for free to see real-time agent collaboration in action. Share your feedback on our community forum. We’re already planning enhancements, like new MCP-integrated agents, enabling secure communication between the AI agents and MCP servers and more. NOTE: This example uses mock data and is intended for demonstration purposes rather than production use. The Challenge: Scaling Personalized Travel Planning Travel agencies grapple with complex tasks: analyzing diverse customer needs, recommending destinations, and crafting itineraries, all while integrating real-time data like trending spots or logistics. Traditional systems falter with latency, scalability, and coordination, leading to delays and frustrated clients. The AI Travel Agents tackles these issues with a technical trifecta: LlamaIndex.TS orchestrates six AI agents for efficient task handling. MCP equips agents with travel-specific data and tools. Azure Container Apps ensures scalable, serverless deployment. This architecture delivers operational efficiency and personalized service at scale, transforming chaos into opportunity. LlamaIndex.TS: Orchestrating AI Agents The heart of The AI Travel Agents is LlamaIndex.TS, a powerful agentic framework that orchestrates multiple AI agents to handle travel planning tasks. Built on a Node.js backend, LlamaIndex.TS manages agent interactions in a seamless and intelligent manner: Task Delegation: The Triage Agent analyzes queries and routes them to specialized agents, like the Itinerary Planning Agent, ensuring efficient workflows. Agent Coordination: LlamaIndex.TS maintains context across interactions, enabling coherent responses for complex queries, such as multi-city trip plans. LLM Integration: Connects to Azure OpenAI, GitHub Models or any local LLM using Foundy Local for advanced AI capabilities. LlamaIndex.TS’s modular design supports extensibility, allowing new agents to be added with ease. LlamaIndex.TS is the conductor, ensuring agents work in sync to deliver accurate, timely results. Its lightweight orchestration minimizes latency, making it ideal for real-time applications. MCP: Fueling Agents with Data and Tools The Model Context Protocol (MCP) empowers AI agents by providing travel-specific data and tools, enhancing their functionality. MCP acts as a data and tool hub: Real-Time Data: Supplies up-to-date travel information, such as trending destinations or seasonal events, via the Web Search Agent using Bing Search. Tool Access: Connects agents to external tools, like the .NET-based customer queries analyzer for sentiment analysis, the Python-based itinerary planning for trip schedules or destination recommendation tools written in Java. For example, when the Destination Recommendation Agent needs current travel trends, MCP delivers via the Web Search Agent. This modularity allows new tools to be integrated seamlessly, future-proofing the platform. MCP’s role is to enrich agent capabilities, leaving orchestration to LlamaIndex.TS. Azure Container Apps: Scalability and Resilience Azure Container Apps powers The AI Travel Agents sample application with a serverless, scalable platform for deploying microservices. It ensures the application handles varying workloads with ease: Dynamic Scaling: Automatically adjusts container instances based on demand, managing booking surges without downtime. Polyglot Microservices: Supports .NET (Customer Query), Python (Itinerary Planning), Java (Destination Recommandation) and Node.js services in isolated containers. Observability: Integrates tracing, metrics, and logging enabling real-time monitoring. Serverless Efficiency: Abstracts infrastructure, reducing costs and accelerating deployment. Azure Container Apps' global infrastructure delivers low-latency performance, critical for travel agencies serving clients worldwide. The AI Agents: A Quick Look While MCP and Azure Container Apps are the stars, they support a team of multiple AI agents that drive the application’s functionality. Built and orchestrated with Llamaindex.TS via MCP, these agents collaborate to handle travel planning tasks: Triage Agent: Directs queries to the right agent, leveraging MCP for task delegation. Customer Query Agent: Analyzes customer needs (emotions, intents), using .NET tools. Destination Recommendation Agent: Suggests tailored destinations, using Java. Itinerary Planning Agent: Crafts efficient itineraries, powered by Python. Web Search Agent: Fetches real-time data via Bing Search. These agents rely on MCP’s real-time communication and Azure Container Apps’ scalability to deliver responsive, accurate results. It's worth noting though this sample application uses mock data for demonstration purpose. In real worl scenario, the application would communicate with an MCP server that is plugged in a real production travel API. Key Features and Benefits The AI Travel Agents offers features that showcase the power of MCP and Azure Container Apps: Real-Time Chat: A responsive Angular UI streams agent responses via MCP’s SSE, ensuring fluid interactions.

The Age of Prompt-Driven Development A significant shift is underway in the way we develop software. AI agents and prompt-based tools are shaping modern development. As a developer, you don’t want to miss this shift. Knowing how to use these tools puts you ahead. Instead of writing endless boilerplate, you can now describe what you want, and AI will generate code, create your database, connect APIs, and even deploy your app. New tools like Cursor, Windsurf, Lovable, and Bolt are rising fast. You can create stunning apps and websites by chatting with AI. Even with all these fancy tools, full-stack apps still need a solid backend, and that means data. Every application needs to work with data. Whether you’re building a blog, a booking platform, or an AI Agent, you’ll need to store and retrieve information. That usually means using a real database like PostgreSQL, MySQL, or MongoDB (unless you’re treating Excel or Google Sheets like a backend, which… we’ve all done once). So schema design, database setup, and API generation can’t be skipped. I decided to experiment with automating the process of designing a database schema, running a database, and managing data using just prompts using GitHub Copilot in VS Code. Working with databases is often repetitive work and slows developers down. I think the issues we always face are the following during the setup of a database from scratch. Every App Needs a Database — It’s Time to Simplify It You start with a manual schema setup You have to create tables, think through relationships, indexes, data types, and naming. You map tables to objects using ORM libraries and build APIs to access that data. It’s easy to miss things or overcomplicate at an early stage. Schema changes are painful Your app evolves. You rename a column, split a table, or add a new relation. Now you need to write migrations. Update your ORM. Avoid downtime. And hope nothing breaks in staging or production. Every change triggers more boilerplate Once the schema changes, you usually: Update model files Fix serializers or DTOs Rewrite REST API endpoints or GraphQL resolvers Modify test data and fixtures That’s a lot of work for just one change. Team coordination becomes tricky In team projects, syncing schema changes between developers often leads to merge conflicts, broken migrations, or inconsistent environments. But now? With the rise of AI code generation tools like GitHub Copilot, you can extend Copilot Chat with the Model Context Protocol (MCP) from external providers, and you can create a fully working database schema with a single prompt — right inside VS Code. And it’ll save you hours every week. Let me show you how you can achieve this. Let’s Build: A Travel Agency App Schema What You Need VS Code (with GitHub Copilot enabled) UV is installed. GibsonAI -Sign up for a free account - This tool turns your prompt into a complete schema, deploys a serverless database, and gives you a live REST API for managing data. Step 1: Set Up GibsonAI CLI and Log In Before using the GibsonAI MCP server, install GibsonAI’s CLI and log in: uvx --from gibson-cli@latest gibson auth login This logs you into your GibsonAI account so you can start using all CLI features. Step 2: Enable MCP Server in VS Code To use the GibsonAI MCP server inside your VS Code project, you’ll need to add a configuration script. Create a file in your project or inside an empty folder called mcp.json in the .vscode/folder. This file defines which GibsonAI MCP server to use for this project. Copy and paste the following content into the .vscode/mcp.json file: { "inputs": [], "servers": { "gibson": { "type": "stdio", "command": "uvx", "args": ["--from", "gibson-cli@latest", "gibson", "mcp", "run"] } } } Once this file is added, GibsonAI tools inside VS Code will connect to the MCP server. Step 3: Describe Your Travel App Schema in a Prompt Open GitHub Copilot Chat in VS Code, switch to Agent mode, and select the LLM model, such as GPT-4.1 or GPT-4o. You should see the available tools from GibsonA Then enter a prompt like this: “Create a database for a travel agency. It should include tables for destinations, bookings, users, and reviews. Each user can make bookings and write reviews. Each destination has a name, description, price, and rating.” GibsonAI reads your prompt, creates a new database project, and magically generates: A complete relational schema Visual Entity-Relationship Diagram (ERD) Proper foreign key constraints UUIDs, timestamps, and standard fields A clean MySQL or Postgres structure Step 4: Deploy Your Schema and Enable CRUD APIs Go to the GibsonAI app, log in, and open your newly created project. There, you can see and review the schema. Now you can click “Deploy” to launch your schema: Alternatively, you can use Copilot chat to deploy the database. GibsonAI hosts the serverless MySQL database. Now you can get the database connection string and connect to your existing app. Or access live CRUD APIs and use them in your app: You now have a working backend without writing a single SQL query. You can plug these APIs directly into your frontend or backend — no need to write REST controllers for typical CRUD operations. GibsonAI also lets me share my database project schema with others. Feel free to clone the travel agency database I created for the demo: https://app.gibsonai.com/clone/rRZ4wD9HDCdHO Step 5: Let Copilot Help You Build Around the API Now that your schema and API are live, use GitHub Copilot to build UI components using React or any other frontend frameworks. GitHub Copilot + GibsonAI MCP = the fastest way to go from prompt to full-featured app. Final Thoughts The future of development is not about using more AI-generated code. It’s about writing fewer, smarter prompts — and letting AI handle the slow, repetitive, or painful tasks so you can fully focus on the innovation. You can already boost your development workflow with GitHub Copilot Agent Mode. It will provide you with a powerful set of tools that enable agents to run SQL queries, create tables, design schemas, import CSV files, and more. Give it a try. The next time you start a project, open VS Code, write a prompt, and let the database build itself.
