EvolutionDB Long-Term Memory

Gives Claude persistent memory backed by EvolutionDB, a single-process database that combines SQL, vector search, and temporal queries. Instead of rigging up separate stores for chat history, embeddings, and checkpoints, you get first-class DDL like CREATE MEMORY STORE and CREATE CHECKPOINT STORE with native LangGraph and LangChain adapters. Runs locally via Docker on ports 5433 (Postgres wire) and 9967 (native), speaks stdio to Claude Desktop, and includes push notifications so you can skip polling loops. Reach for this when you want agents to remember context across sessions without stitching together MongoDB and Pinecone or writing your own checkpoint serializer.
