Security Report

5.2
Moderate5.2Moderate Risk

This is a well-structured MCP server for querying a Nostr-native music catalog with no authentication requirements (by design, as it reads public data). The codebase is clean, properly handles Nostr event verification, uses appropriate error handling, and permissions align well with its read-only purpose. Minor findings around error handling and input validation do not materially impact security. Supply chain analysis found 2 known vulnerabilities in dependencies (0 critical, 1 high severity). Package verification found 1 issue (1 critical, 0 high severity).
