Security Report

6.2

Moderate6.2Moderate Risk

This is a well-structured MCP server for accessing exchange rate data. Authentication via API key is properly required and enforced, credentials are correctly stored in environment variables, and the codebase is clean with no malicious patterns. Input validation relies on schema definitions and the API backend, which is appropriate for this use case. The server's permissions (network HTTP only) are proportionate to its stated purpose. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.
