Security Report

4.2

Use Caution4.2High Risk

A browser automation MCP server with event-driven snapshots and governance gates. The codebase demonstrates thoughtful security design with HITL confirmation for sensitive operations, audit logging, and permission-appropriate functionality. However, moderate concerns include environment variable-based configuration without type validation, broad browser permissions, and potential timing-race vulnerabilities in state management that could allow unintended operations. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
