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 tries to reach the network on start. The probe runs in a container with the network off, so a server that connects lazily, on the first tool call, is measured.
