We add a row when the result changes. A server with no change keeps its last row.

The result of the latest probe, the tool count and the token cost. The feed has an entry for every probe that changed them.

Stops answering, comes back, tool set or cost changes. One confirmation mail first, a stop link in every mail.

The server answers HTTP 401 to an unauthenticated initialize, so the probe cannot list its tools. That is correct for a private server. Some public servers answer initialize and tools/list without credentials and ask for auth on tool calls only; those get a token count here.

Fixed something? Probe it now, with the same steps as the daily run. This page updates with the next daily run.
