Whimsical does not always answer

Over the last week it answered 98.1% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

This endpoint answered with an authorization challenge — the server is running, but you need an API key or OAuth to use it.

Whimsical — questions

Answers built from our own checks of this server.

Why is there no tool list for Whimsical?

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: 96.7% of checks in the last 24 hours got a reply.

Is Whimsical working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 89 of 92 checks got a reply (96.7%), average response time 256 ms. The bar chart above shows every period we have measured.

How do I connect Whimsical?

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 sign in through your browser once and the client keeps the session: no key to copy, and it refuses anonymous clients.

How do you sign in to Whimsical?

No API key is involved. Whimsical answers our knock with an OAuth challenge, so you authorise it once in your browser and the client keeps the session. That is also why we see no tool list: it will not describe itself to an anonymous client, and that is the server working as intended, not a fault.

How fast is Whimsical?

It answers our handshake in 256 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is Whimsical open source?

Yes — it is published under the MIT licence and 5 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.
