Mem0 MCP Server with Anthropic Claude

A local Mem0 memory system configured to work with Anthropic's Claude API and MCP (Model Context Protocol).

Features

✅ Vector storage with Qdrant
✅ Graph database with Neo4j (to be configured)
✅ Metadata storage with PostgreSQL
✅ Anthropic Claude 3.5 Sonnet integration
✅ MCP server for Claude Code integration

Prerequisites

Docker and Docker Compose
Python 3.12+
Anthropic API key (Claude subscription)

Quick Start

Clone the repository

git clone <your-repo-url>
cd mem0-setup

Set up environment variables

cp .env.example .env
# Edit .env and add your MEM0_ANTHROPIC_KEY

Start the databases

docker compose up -d

Install Python dependencies

pip install -r requirements.txt

Run the Mem0 server

source .env
python3 mem0_server.py

The server will be available at http://localhost:8765

Architecture

Qdrant: Vector database for semantic search
Neo4j: Graph database for relationship storage (optional)
PostgreSQL: Metadata and configuration storage
FastAPI: REST API server
MCP: Model Context Protocol integration

Configuration

The system uses MEM0_ANTHROPIC_KEY instead of ANTHROPIC_API_KEY to avoid conflicts with Claude's own authentication.

API Endpoints

GET /health - Health check
POST /memories - Add a memory
POST /memories/search - Search memories
GET /memories - Get all memories
PUT /memories/{memory_id} - Update a memory
DELETE /memories/{memory_id} - Delete a memory

MCP Integration

For Claude Code integration, add to your .mcp.json:

{
  "mcpServers": {
    "mem0": {
      "command": "python3",
      "args": ["/path/to/mem0_stdio_mcp.py"]
    }
  }
}
