Security Report

4.2

Use Caution4.2High Risk

This MCP server implements a budget management system with x402 USDC micropayment authentication. The codebase demonstrates solid security fundamentals with proper input validation, reasonable permission scope aligned with its financial analytics purpose, and appropriate use of environment variables for sensitive configuration. However, several moderate concerns exist: Supabase credentials are loaded from environment but not validated at startup, database queries lack parameterization safeguards, and error messages could leak sensitive information. The server's broad database access is justified by its purpose but introduces supply-chain risk through the Supabase dependency. Supply chain analysis found 11 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue (1 critical, 0 high severity).
