Security Report
2.2
Use Caution2.2Critical RiskThis MCP server implements a cryptocurrency payment system (x402 protocol) for data access with generally sound architecture, but contains several security concerns that warrant user awareness. The private key handling is environment-variable based (good), but the server automatically signs and submits blockchain transactions on behalf of the user without explicit per-transaction confirmation, which creates financial risk. Additionally, the hardcoded Worker URL and recipient address reduce user control, and there are minor input validation gaps. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
