Security Report

7.0

Moderate7.0Moderate Risk

This FlightAware AeroAPI MCP server is well-structured with proper authentication, secure credential handling, and appropriate permission scoping. The API key is correctly loaded from environment variables, authentication is enforced at request time, and mutating operations are gated behind confirmation flags. Minor code quality findings around error handling and input validation do not materially impact security posture. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
