Nothing serious here today

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

Reference — questions

Answers built from our own checks of this server.

Why is there no tool list for Reference?

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 Reference 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 2385 ms. The bar chart above shows every period we have measured.

How do I connect Reference?

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 will need your own credentials: it refuses anonymous clients.

Does Reference need an API key?

Yes. Every time we knock, Reference answers with an authorization challenge instead of its tool list — that is how we know it is running and gated rather than broken. Bring your own credentials and it will talk.
