Triage MCP server failures with mcptoon
Work top-down; stop as soon as the layer with the fault is found.
1. Read the config layer first
mcptoon doctor
Catches: invalid JSON, unknown fields, missing binaries for stdio commands, malformed URLs. Fix anything reported before deeper probing.
2. Check connectivity
mcptoon health # every server, human-readable
mcptoon health --json # CI/CD friendly, exit 1 if any dead
3. Probe the tool layer
mcptoon list # is the server even registered?
mcptoon manifest --compact # do its tools appear at all?
mcptoon inspect <server> <tool> # full schema of one tool
mcptoon call <server> <tool> '{}' --toon # minimal live call
