elvismdev/mem0-mcp-selfhosted

Overview

This tool provides a self-hosted memory server for Claude Code using the MCP protocol. It stores conversation history in Qdrant for vector embeddings and Neo4j for graph relationships, with Ollama generating local embeddings while Claude acts as the primary LLM.
