Mem0 Self-Hosted

What it does

Connects Claude Code to a self-hosted memory infrastructure, allowing the AI to remember project architecture, user preferences, and debugging insights across sessions. It leverages a combination of vector search for semantic recall and a knowledge graph for entity relationships.

Tools

• add_memory: Stores text or conversation history as persistent memories.
• search_memories: Semantic search for relevant context with optional reranking.
• get_memories: List or filter memories based on scope.
• update_memory: Modifies existing memory text and re-indexes it.
• delete_memory: Removes a specific memory by UUID.
• list_entities: Lists users, agents, and runs with associated memory counts.
• search_graph: Searches the Neo4j knowledge graph for entities and relationships.
• get_entity: Retrieves all bidirectional relationships for a specific entity.
