Create MCP (Model Context Protocol) servers that enable LLMs to interact with external services through well-designed tools. The quality of an MCP server is measured by how well it enables LLMs to accomplish real-world tasks. -- Microsoft provides extensive MCP infrastructure for Azure and Foundry services. Understanding this ecosystem helps you decide whether to build custom servers or leverage existing ones. | Type | Transport | Use Case | Example | |------|-----------|----------|---------| | Local | stdio | Desktop apps, single-user, local dev | Azure MCP Server via NPM/Docker | | Remote | Streamable HTTP | Cloud services, multi-tenant, Agent Service | https://mcp.ai.azure.com (Foundry) | Before building a custom server, check if Microsoft already provides one: | Server | Type | Description | |--------|------|-------------| | Azure MCP | Local | 48+ Azure services (Storage, KeyVault, Cosmos, SQL, etc.) | | Foundry MCP | Remote | https://mcp.ai.azure.com - Models, deployments, evals, agents | | Fabric MCP | Local | Microsoft Fabric APIs, OneLake, item definitions | | Playwright MCP | Local | Browser automation and testing | | GitHub MCP | Remote | https://api.githubcopilot.com/mc
