Security Report

4.2

Use Caution4.2High Risk

claude-faf-mcp is a well-intentioned developer tools MCP server with reasonable security architecture. Path confinement is properly implemented to prevent directory traversal, and permissions align with its purpose as a project context/scoring tool. However, several code quality and operational security concerns exist: environment variable exposure in debug output, overly broad exception handling, potential process-spawn capability without explicit documentation, and limited input validation on some file operations. The server requires careful deployment in trusted environments. Supply chain analysis found 11 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue.
