Description
Preflight checks an MCP server for real security gaps before your agent connects: unauthenticated transport, capability grants with no scoping, known-bad description signatures, and a semantic pass reading tool descriptions for injected instructions aimed at the model. Free tier is real: 20 scans/minute, no signup. Tested against real production servers (Linear, Sentry, Atlassian) so it doesn't cry wolf on things already secured properly. Built by All the Possibles.

Could you build this?
Yes An MCP security scanner simply connects to an MCP JSON-RPC server, inspects advertised tool schemas/descriptions, and runs heuristic and LLM checks for prompt injections.
