M365 Graph MCP — questions

Answers built from our own checks of this server.

Why is there no tool list for M365 Graph MCP?

The server answered our handshake with an authorization challenge, so it is running — but it will not describe its tools to an anonymous client. To see them you need to connect with your own credentials. We record it as alive, not as broken: 84.6% of checks in the last 24 hours got a reply.

Is M365 Graph MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 77 of 91 checks got a reply (84.6%), average response time 723 ms. The bar chart above shows every period we have measured.

How do I connect M365 Graph MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address. You sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to M365 Graph MCP?

No API key is involved. M365 Graph MCP answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is M365 Graph MCP?

It answers our handshake in 723 ms on average, which is faster than 11% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
