Security Report

6.2
Moderate6.2Moderate Risk

brain-mcp is a local-only conversation recorder with well-designed security principles (offline operation, no network calls, verifiable citations). However, several code quality and permission-handling issues introduce moderate-risk vulnerabilities: unrestricted file reads via path traversal checks that are insufficient, unsafe subprocess usage without input validation, and broad filesystem permissions. The server's stated purpose (local AI conversation archival) justifies most permissions, but implementation details require hardening. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.
