amu-pgvector MCP

A community-driven MCP server providing lineage-gated agent memory tools on PostgreSQL and pgvector. It enforces row-level security to prevent data leaks by gating memory reuse based on derivation lineage rather than just content tags, ensuring agents only access cached results they are permitted to see.
