Security Report

3.2

Use Caution3.2High Risk

This MCP server implements outcome verification with x402 USDC micropayments on Solana. While the x402 payment mechanism provides authentication for paid tools and the code lacks obvious malicious patterns, several security concerns lower the score: Supabase credentials must be environment-loaded but are not validated, the Grok API client is referenced but its implementation is missing (preventing full security review), error handling in JSON parsing is broad, and there is no input validation on service_id parameters. The permissions align reasonably with the server's stated purpose (external APIs, file operations, environment variables), but the missing dependency code and lack of defensive validation create moderate risk. Supply chain analysis found 11 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
