The author released an open-source MCP security scanner and tested it against the "Damn Vulnerable MCP Server". Results show static and dynamic analysis detected 30% of canonical challenges and 40% in real Docker environments, with zero false positives on clean servers. The free tier covers basic checks; advanced LLM-based analysis for semantic poisoning is a paid tier due to costs.
