Overview • Architecture • Getting started • Deploy to Azure • Run locally • MCP tools • Resources [!IMPORTANT] 👉 Follow the full-length workshop to learn how we built this sample. Overview This project demonstrates how to build AI agents that can interact with real-world APIs using the Model Context Protocol (MCP) . It features a complete burger ordering system with a serverless API, web interfaces, and an MCP server that enables AI agents to browse menus, place orders, and track order status. The agent uses LangChain.js to handle LLM reasoning and tool calling. The system consists of multiple interconnected services, as detailed in the Architecture section below. The system is hosted on Azure Static Web Apps (web apps) and Azure Functions (API and MCP servers), with Azure Cosmos DB for NoSQL for data storage. You can use it as a starting point for building your own AI agents. [!TIP] You can test this application locally without deployment needed or any cloud costs. The MCP server also works with popular AI tools like GitHub Copilot, Claude, and other MCP-compatible clients. Follow the instructions in the Local Development section to get started. Key features - LangChain.js agent with tool calling via MCP (Streamable HTTP transport) - Multi-service, end‑to‑end architecture (web UIs, APIs, MCP server) - User authentication with sessions history - 100% serverless architect","default_branch":null,"files":null,"tree":[],"storefront":"/r/Azure-Samples","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/Azure-Samples/mcp-agent-langchainjs/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
