The badge shows the most recent probe. It is generated from the same file this page is, updates once a day, and needs no key.

What was actually measured

One HTTP POST carrying a JSON-RPC initialize, and if that succeeds, a tools/list. Nothing here is a score, a rating or a judgement about whether the server is any good — only whether an ordinary MCP client could complete a session with it on the day we asked. “Needs credentials” is not a fault: it means the endpoint wants an account, which is a perfectly reasonable thing for it to want.

The tool contract row is a digest of what tools/list returned — each tool's name, description and input schema, hashed — so that a rename, a newly-required field or a rewritten description can be spotted even though none of them breaks the connection. We keep the digests and nothing else: no tool name, description or schema of anybody's is stored or republished here, which is also why this can say that a contract moved and by how much, but not what it now says.
