概览

What is MCP Server for the Microsoft Graph Api?

An MCP (Model Context Protocol) server written in C# that enables AI assistants (such as Claude or Azure OpenAI) to interact with the Microsoft Graph API and answer questions about your Microsoft Entra tenant.

How to use MCP Server for the Microsoft Graph Api?

Register an Entra ID application with at least User.Read.All permission, then configure the server in claude_desktop_config.json with your tenant ID, client ID, client secret, and optional national cloud endpoint. Build the solution, and the MCP server will be automatically discovered by the Claude Desktop app.

Key features of MCP Server for the Microsoft Graph Api

Connects AI assistants to the Microsoft Graph API
Supports multiple national clouds (Global, US Gov, China, Germany)
Uses app‑only authentication via Entra ID client secret
Exposes Graph API tools through the Model Context Protocol
Compatible with Claude Desktop and any MCP client
Optionally works with Azure OpenAI Service or Anthropic Claude API

Use cases of MCP Server for the Microsoft Graph Api

Let an AI assistant query user or group information from your Microsoft 365 tenant
Automate common administration tasks by sending natural language requests to Microsoft Graph
Integrate Copilot or similar tools with your tenant’s directory data

常见问题

What runtime and dependencies are required?

The project is a .NET console application built with C#. You need the .NET SDK installed to build and run it (using the `dotnet` command).

How does authentication work?

The server uses an Entra ID application with a client secret (app‑only authentication). You must grant at least the `User.Read.All` application permission and provide the tenant ID, client ID, and client secret in environment variables.

Can I use a national cloud other than the global Microsoft Graph service?

Yes. Set the `NATIONAL_CLOUD` environment variable to `Global`, `US_GOV`, `US_GOV_DOD`, `China`, or `Germany` to target the corresponding Microsoft Graph endpoint.

Which transports and authentication are supported by the MCP server?

The server uses command‑line stdio (standard input/output) for transport, as configured in `claude_desktop_config.json`. Authentication is always via Entra ID client credentials.

Where are logs stored if something goes wrong?

When using Claude Desktop, logs can be found in `%APPDATA%\Claude\logs` on Windows.
