Mem0 Memory MCP

A self-hosted MCP server that gives AI assistants persistent, searchable long-term memory built on Mem0. Stores facts and preferences across sessions, retrieves them by semantic search, and can back memories with a Neo4j knowledge graph plus smart chunking, so an agent keeps useful context between conversations instead of starting cold.
