ONCE — AI Agent Huddle — questions

Answers built from our own checks of this server.

Why is there no tool list for ONCE — AI Agent Huddle?

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 ONCE — AI Agent Huddle 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 194 ms. The bar chart above shows every period we have measured.

How do I connect ONCE — AI Agent Huddle?

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 will need your own credentials: it refuses anonymous clients.

Does ONCE — AI Agent Huddle need an API key?

Yes. Every time we knock, ONCE — AI Agent Huddle 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.

How fast is ONCE — AI Agent Huddle?

It answers our handshake in 194 ms on average, which is faster than 63% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
