About Memory Vault
Memory Vault is an MCP server published by the GitHub account MihaiBuilds. Local-first AI memory layer with hybrid search. Postgres + pgvector. Self-hosted, MIT.
It runs on your own machine: your AI client starts it from the Docker (OCI) package ghcr.io/mihaibuilds/memory-vault-mcp:1.6.1, with no version pinned.
It asks for one secret: DB_PASSWORD. Give it a key with the least access that still works.
It also needs DB_HOST, DB_PORT, DB_NAME and DB_USER set before it starts.
Version 1.6.1 was published on 9 October 2026, and the source code is public, so you can read it before installing.
Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.
