Show HN: MCPHound MCP servers together, create attack paths solo scanners miss (github.com)

MCPhound has launched a security scanner specifically for Multi-Channel Protocol (MCP) configurations, designed to identify complex attack paths that arise when multiple MCP servers interact. This tool can expose risks such as tool poisoning, typosquats, known vulnerabilities, and supply chain issues in AI tool setups. By executing a simple command (`npx mcphound`), users can automatically detect configurations across popular AI platforms like Claude and Cursor, revealing cross-server vulnerabilities that might be overlooked by other individual server scanners. The significance of MCPhound lies in its unique ability to build a network graph of interconnected servers, running 16 distinct attack pattern analyses to uncover potential multi-hop exploit chains—situations where an attack vector materializes when multiple servers collaborate. Its advanced scanning capabilities include regex patterns to detect harmful instructions within tool descriptions and a trust scoring system that evaluates server reliability based on various metrics. With its comprehensive analysis and grading system, MCPhound stands to enhance security protocols within the AI/ML community, ensuring safer configurations and deployment practices.
