Microsoft open-sources official MCP server directory repo microsoft/mcp

The repo includes core libraries, test frameworks, pipelines, and engineering tools shared by Microsoft MCP server contributors to unify investment and reduce duplication and forking. It also serves as an official server list covering Azure, Microsoft Fabric, GitHub, Microsoft 365, Microsoft Dataverse, Microsoft SQL, Microsoft Learn, and others, each entry listing the repo, description, category, and local or remote type with install method. For example, Azure MCP is a local server bundling all Azure tools into one service; Foundry, Azure Resource Manager, GitHub, and Microsoft Learn are offered as remote endpoints; Binlog MCP installs via a NuGet global tool, while the M365 series uses remote addresses with a tenant ID. Developers using Claude Desktop or other MCP-compatible clients can follow the list to connect Azure resources, Fabric data, SQL databases, GitHub issues and PRs, and M365 mail, calendar, and documents into their AI assistant without writing an adapter layer. For those doing Azure development with GitHub Copilot in VS Code, Azure MCP can also work with the Copilot for Azure extension; teams maintaining .NET builds can use Binlog MCP to let agents analyze build errors, warnings, and targets in .binlog files to help debug CI failures.
