Security Report

1.5

Use Caution1.5Critical Risk

This MCP server implements email verification with payment gating via x402 and ATXP protocols. Critical security issues include hardcoded cryptocurrency wallet address and API credentials exposed in source code, missing input validation on email parameters, and reliance on external payment middleware with unclear security posture. The server performs DNS lookups on user-supplied domains without rate limiting or SSRF protections, creating potential for abuse. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 3 high severity).
