This one has been quiet for a while

Quiet is not dead — but it is worth knowing when it wakes up, or when someone else takes it over. We watch the repository and tell you either way.

This endpoint answered with an authorization challenge. The server is running, and it signs you in through your browser: there is no API key to paste.

Outlook Calendar — questions

Answers built from our own checks of this server.

Why is there no tool list for Outlook Calendar?
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: 100.0% of checks in the last 24 hours got a reply.
Is Outlook Calendar working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 234 ms. The bar chart above shows every period we have measured.
Is Outlook Calendar still maintained?
No commits for 12 months. We show this because it changes what you can expect: an unmaintained server may keep answering for months and then stop without warning.
How do I connect Outlook Calendar?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path 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 Outlook Calendar?
No API key is involved. Outlook Calendar 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 Outlook Calendar?
It answers our handshake in 234 ms on average, which is faster than 60% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Outlook Calendar open source?
We cannot say either way: 9 stars on GitHub and 1 open issue, but we could not determine the licence, and without one the code is not open source by default.
