Security Report

6.2
Moderate6.2Moderate Risk

This is a well-architected MCP server for querying London Transport data with appropriate security controls. Authentication is optional (using TfL API keys passed via environment variables, not hardcoded), all operations are read-only queries with no data exfiltration, and input validation is strict via Zod schemas. Minor code quality observations exist around error handling breadth and logging, but do not materially impact security given the server's benign purpose and limited attack surface. Supply chain analysis found 1 known vulnerability in dependencies (1 critical, 0 high severity).
