About
Settlement-grade market weather + general current/forecast weather for any location, via x402.
Security Report
This MCP server implements a weather API client with x402 payment integration. While the code is clean and purposefully scoped, there are critical security concerns: the private key is passed via environment variables without validation or sanitization, and the server lacks input validation on user-supplied parameters (lat/lon/city) that are directly interpolated into API URLs, creating potential injection vectors. The authentication model relies entirely on wallet possession, with no user-level access controls. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
