How we built the Microsoft Learn MCP Server

Microsoft launched the Microsoft Learn MCP Server in June 2025, exposing Learn documentation through a remote MCP service.

It runs on Streamable HTTP Transport with the official C# SDK on Azure App Service, using the same knowledge and vector search backend as Ask Learn.

The design simplifies the tool surface into search and fetch, giving MCP-compatible AI agents standard access to current Microsoft documentation.

This reduces integration and maintenance overhead while helping tools like GitHub Copilot and VS Code provide more grounded answers.
