Security Report
This MCP server exposes 450+ API endpoints with significant security and architectural concerns. The code requires API keys for authentication but lacks input validation, error handling, and proper credential management patterns. Critical issues include unauthenticated internal discovery tools, unvalidated pass-through to external APIs, and a sprawling tool surface that creates substantial attack surface. The server's design prioritizes breadth over security, with minimal guardrails on what agents can access or do with integrated services. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue (1 critical, 0 high severity).
