Security Report

4.2

Use Caution4.2High Risk

PayanAgent is a well-architected marketplace platform with strong authentication and authorization controls. The codebase demonstrates careful separation of concerns, proper secret handling, and comprehensive validation. However, moderate concerns exist around environment variable handling in the MCP package, broad network permissions for external API relays, and some error handling gaps that could leak sensitive information. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 1 high severity). Package verification found 1 issue (1 critical, 0 high severity).
