Security Report
5.7
Moderate5.7Moderate RiskThis is a well-structured MCP server with appropriate authentication, reasonable permissions, and clean code. The server requires a PostWire API key for operation, uses standard OAuth Bearer token authentication, and makes only expected network calls to the PostWire API. One minor code quality issue exists around error handling specificity, but this does not materially affect security. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.
