Memory Vault

Gives Claude four tools to store and retrieve memories from a self-hosted Postgres database with pgvector. It runs hybrid search combining semantic similarity and keyword matching, so you can recall past decisions or project context without re-explaining everything. The remember tool auto-classifies and embeds text, recall searches across memory spaces, forget soft-deletes by chunk ID, and memory_status reports database health. Runs on stdio transport and connects to your local Postgres instance. Useful if you want persistent context across Claude sessions without cloud storage or if you're building AI tools that need to remember state between conversations.
