Openhouse does not always answer
Over the last week it answered 99.3% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Openhouse — questions
Answers built from our own checks of this server.
What can Openhouse do?
It exposes 30 tools, read directly from the server on our last check. Among them: beacon, canon_cite, canon_search, check, commons, compute_collect and 24 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
What is Openhouse mostly used for?
Its tools cluster around job, locker and canon. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.
Is Openhouse working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 92 checks got a reply (98.9%), average response time 1056 ms. The bar chart above shows every period we have measured.
Is Openhouse still maintained?
The linked repository no longer exists on GitHub — it was deleted or made private. 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 Openhouse?
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 Openhouse need an API key?
No. Openhouse completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 30 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Openhouse?
It answers our handshake in 1056 ms on average, which is faster than 8% 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.
