Security Report

5.2
Moderate5.2Moderate Risk

Cheaplane is a well-designed MCP server with strong security fundamentals. Authentication is properly scoped to a local proxy with isolated credentials, network access is appropriate for its cost-optimization purpose, and the codebase is clean with minimal dependencies. Minor code quality issues around error handling and input validation do not materially impact security, and file operations are appropriately scoped. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
