MCP server for x402 — HTTP-native micropayments protocol by Coinbase (USDC on Base/Solana)
This is a large MCP server monorepo (109 servers, 2,289 tools) for Latin American commerce APIs. The Sift fraud-detection server analyzed here has proper authentication (Basic auth + event API key injection), no malicious patterns, and reasonable permissions for its purpose. However, the codebase exhibits several moderate-severity issues: hardcoded API credentials in example files, overly broad exception handling, missing input validation on user-supplied fields, and insufficient credential isolation in some areas. Permissions are appropriate for a payments/commerce category server, but the breadth of the catalog itself (network access to 100+ regional APIs) creates inherent operational risk that users should understand. Supply chain analysis found 2 known vulnerabilities in dependencies (1 critical, 0 high severity). Package verification found 1 issue (1 critical, 0 high severity).
