mem0-mcp-selfhosted

Overview

This is a complete MCP server implementation for mem0, enabling persistent memory across Claude Code sessions. It provides 11 MCP tools for memory management and supports both cloud-based Anthropic (Claude) and fully local Ollama configurations. The server integrates multiple backend services including Qdrant for vector storage, Neo4j for knowledge graphs, and Ollama for embeddings and optionally LLM services. The implementation is production-ready with comprehensive documentation, multiple authentication methods, and session hooks for automatic memory injection and saving.

FAQ

Can I use this MCP server with AI providers other than Anthropic and Ollama?

Currently, the server supports Anthropic (Claude) and Ollama as LLM providers. The embedding generation uses Ollama with bge-m3 by default, but this could potentially be configured for other embedding models.

What's the difference between hooks and CLAUDE.md rules for memory management?

Hooks handle automatic memory at session boundaries - injecting memories on startup and saving summaries on exit. CLAUDE.md rules provide behavioral instructions that tell Claude to actively search and save memories during the session. Using both together provides the best experience.
