Security Report

4.2

Use Caution4.2High Risk

This is a well-structured MCP server for agent governance with proper security patterns. However, it executes arbitrary shell commands without validation and has hardcoded secrets in the codebase, which present moderate security concerns despite the legitimate governance purpose. Supply chain analysis found 6 known vulnerabilities in dependencies (0 critical, 6 high severity). Package verification found 1 issue.
