Security Report

4.2

Use Caution4.2High Risk

This is a legitimate MCP server for Japanese invoice/receipt OCR with x402 payment integration. The codebase is well-structured with proper authentication (x402 wallet-based payments), clear scope (document processing, registry lookups), and reasonable permissions for its purpose. However, there are several code quality and security concerns: private key handling in environment variables without explicit warnings about secure storage, insufficient input validation on file size checks for base64-encoded data, and some error handling gaps that could leak sensitive information. Supply chain analysis found 9 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue (1 critical, 0 high severity).
