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.
