Security Report

5.2

Moderate5.2Moderate Risk

A well-designed Bitwarden/Vaultwarden MCP server with strong security architecture. The implementation properly enforces opt-in exposure, uses E2E encryption for secret delivery, and includes comprehensive safety tests. Minor code quality issues (broad error handling, incomplete test file) and a missing input validation edge case prevent a higher score, but permissions and authentication are appropriate for the server's purpose. Supply chain analysis found 4 known vulnerabilities in dependencies (1 critical, 3 high severity). Package verification found 1 issue.
