Safe MCP protocol inspection

Is your MCP server easy for models to use?

Test initialization, protocol metadata, tools/list, names, descriptions, JSON Schemas, output contracts, and safety hints. The doctor performs discovery only and never calls a tool.

What gets sent

The doctor performs the standard MCP initialize handshake, sends notifications/initialized, then requests tools/list. It does not send tools/call, prompts/get, resources/read, or any mutation request. Protected servers may return an authentication finding without exposing their tool catalog.
