Mcprobe
An MCP server that audits other MCP servers. Connects to any stdio/HTTP target, lints every tool's schema, then fuzzes the tools with deliberately broken inputs to catch silent failures static checks miss — and returns a 0–100 conformance score. Black-box, no source needed. It even audits itself.
