Call this server's tools from your browser. Nothing to install.

Use after an HTTP, API, or MCP request fails, or when transport succeeds but the expected result is missing or incorrect. Send only the sanitized error from the latest request and its system. Returns advisory, evidence-linked recovery steps; never executes fixes. Never include credentials or personal data. No charge; the x402 paid trial is disabled.
