Security Report

Use Caution4.8High Risk

This is a well-designed MCP server for a legitimate financial service (Ledger API). Authentication via x402 micropayments is properly implemented with secure key handling, input validation is present (transaction balance checking), and permissions appropriately match the server's purpose (network HTTP for API calls, environment variables for wallet keys). Minor code quality observations exist but do not constitute security vulnerabilities. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
