Security Report

5.2

Moderate5.2Moderate Risk

This MCP server demonstrates strong security practices with proper encryption, credential handling via OS keychain, and comprehensive input validation. The code uses libsodium for cryptographic operations, stores sensitive data (master key, session tokens) only in OS keychain or memory, and implements a redacting logger. Minor code quality issues and some broad exception handling do not substantially impact security posture. Supply chain analysis found 4 known vulnerabilities in dependencies (1 critical, 2 high severity). Package verification found 1 issue.
