Nothing serious here today

Today is the operative word: we check Machine Presence Inspector every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.

Machine Presence Inspector — questions

Answers built from our own checks of this server.

Is Machine Presence Inspector working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 409 ms. The bar chart above shows every period we have measured.

How do I connect Machine Presence Inspector?

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.

Does Machine Presence Inspector need an API key?

No. Machine Presence Inspector 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 Machine Presence Inspector?

It answers our handshake in 409 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
