Badge for the README
The result of the latest probe, the tool count and the token cost. The feed has an entry for every probe that changed them.
A mail when this server changes
Stops answering, comes back, tool set or cost changes. One confirmation mail first, a stop link in every mail.
For the publisher
- 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.
