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 exits because an environment variable is missing. The probe starts the package without secrets. A server that starts without secrets and asks for them on the first tool call is measured.
