Security Report

5.2

Moderate5.2Moderate Risk

ARGUS-3 is a well-architected MCP agent with strong security controls. The codebase demonstrates sophisticated defense-in-depth patterns including prompt-injection sanitization, cryptographic sealing, integrity verification, and a comprehensive WARDEN firewall for vetting third-party MCP servers. Code quality is high with proper error handling and permission scoping. Minor concerns around error handling breadth and test coverage for novel post-quantum crypto implementations prevent a higher score, but these do not represent exploitable vulnerabilities. Supply chain analysis found 5 known vulnerabilities in dependencies (2 critical, 3 high severity). Package verification found 1 issue.
