Use Caution4.2High Risk

M3 Memory is a well-architected local-first MCP server with appropriate security controls for its use case. The codebase demonstrates sound engineering practices with no critical vulnerabilities or malicious patterns detected. Permissions align with the stated purpose (persistent memory, file indexing, local embeddings). Minor findings relate to code quality and documentation rather than security issues; the server's offline-by-default design and local-only storage substantially mitigate risk. Supply chain analysis found 3 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
