Security Report

3.8
Use Caution3.8High Risk

The MCP server implements a legitimate x402 payment-gated crypto signals API with proper authentication via blockchain payments and ECDSA signing. However, there are security concerns around environment variable handling, incomplete extra_endpoints.py code, and insufficient input validation on user-supplied parameters that warrant attention. The permissions align with the service's purpose but some potential for data access should be monitored. Supply chain analysis found 22 known vulnerabilities in dependencies (2 critical, 17 high severity). Package verification found 1 issue.
