Security Report
Well-structured MCP server with appropriate authentication via Bearer token, proper input validation, and safe subprocess handling. The server delegates actual linting to kube-linter (external binary) via controlled subprocess calls with timeouts. Minor code quality observations (broad exception handling, logging of check names) do not raise security concerns. Permissions are appropriately scoped to the server's purpose of auditing Kubernetes manifests. Supply chain analysis found 3 known vulnerabilities in dependencies (1 critical, 1 high severity).
