Memory Vault MCP

Memory Vault MCP provides a local-first AI memory layer with hybrid search capabilities using Postgres and pgvector. It exposes four tools—recall, remember, forget, and status—allowing agents to read and write persistent memory within conversations without copy-pasting. The server supports self-hosting via a single Docker image and integrates with Claude Desktop or Claude Code.
