Security Report

4.2

Use Caution4.2High Risk

The AI Firewall MCP server is a security-focused tool with generally solid architecture and reasonable permissions matching its purpose. The codebase demonstrates good security practices (no hardcoded credentials, proper input validation, fail-safe defaults). However, several code quality concerns and a moderate risk around untested error handling in the MCP server layer prevent a higher score. The server appropriately uses environment variables for configuration and has no evidence of data exfiltration or malicious patterns. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
