Security Report

4.2
Use Caution4.2High Risk

observability-mcp is a well-architected MCP server with strong authentication, authorization, and security practices. The codebase demonstrates mature security patterns including RBAC, audit logging, CSRF protection, SSRF guards, and sensitive data redaction. Some low-severity code quality concerns exist (broad exception handling, incomplete input validation in edge cases), but core security mechanisms are sound and permissions are appropriate for the server's purpose as a unified observability gateway. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 4 high severity). Package verification found 1 issue.
