Security Report
This MCP server implements a sophisticated x402 payment protocol for autonomous agent access to federal/financial data APIs. The codebase shows strong security practices in payment handling and audit logging, but has several notable concerns: unsanitized user input in API queries that could enable injection attacks, missing input validation on critical parameters, and overly broad error responses that leak system details. Environment variable handling is reasonable but token trimming workarounds suggest operational hygiene issues. Permissions are appropriate for its purpose (network APIs, env vars for credentials), but the attack surface from unvalidated query parameters is significant. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity).
