Grimoire does not always answer

Over the last week it answered 98.7% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Grimoire — questions

Answers built from our own checks of this server.

Is Grimoire working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 91 checks got a reply (97.8%), average response time 574 ms. The bar chart above shows every period we have measured.

The registry lists Grimoire as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Grimoire?

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.

Does Grimoire need an API key?

No. Grimoire completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. This is what we observed, not what the docs claim.

How fast is Grimoire?

It answers our handshake in 574 ms on average, which is faster than 25% 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.

Is Grimoire open source?

Yes — it is published under the MIT licence, written in Go and 1 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
