What this MCP does

Searches reviewed proxy documentation, generates tested client configurations, and diagnoses proxy connection errors without executing requests.

diagnose_proxy_error
Diagnose a proxy error
Use structured client/version, phase, status or exception observations to identify possible causes and the next check. Returns uncertainty and retry boundaries. Do not send raw logs, URLs or credentials.
