Security Report
4.2
Use Caution4.2High RiskThis MCP server is a legitimate proxy to the flat.cash financial service with reasonable security practices. Authentication is properly handled via environment variables, and the codebase is clean and straightforward. However, auto-registration that prints API keys to stderr, token handling in environment variables, and reliance on a remote service for all functionality introduce moderate operational security considerations that users should understand. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.

- No KYC required — create an account with just a label
- No gas needed — internal transfers are free and instant
- Privacy — BearerSwap enables untraceable transfers
