Better Mem0 MCP

A Model Context Protocol (MCP) server for Mem0, providing memory capabilities to LLMs through the MCP protocol.

Features

• Supports all Mem0 memory operations
• Works with both STDIO and StreamableHTTP transports
• Configurable through YAML files
• Supports user-specific memory contexts
• Easy to deploy via NPX or Docker

Installation & Usage

STDIO Mode (CLI)

Run the MCP server directly using npx:

npx -y @jtsang/better-mem0-mcp@latest

With configuration file and user ID:

npx -y @jtsang/better-mem0-mcp@latest --config ./config.yaml --user-id alice

StreamableHTTP Mode (Docker)

Build and run the Docker image:

# Build the Docker image
docker build -t better-mem0-mcp .

# Run the container
docker run -p 3000:3000 \
  -e OPENAI_API_KEY=your_openai_api_key \
  -e MEM0_USER_ID=alice \
  -v $(pwd)/config.yaml:/app/config.yaml \
  better-mem0-mcp --config /app/config.yaml

Configuration

Create a config.yaml file with your Mem0 configuration:

version: v1.1
embedder:
  provider: openai
  config:
    apiKey: ${OPENAI_API_KEY}
    model: text-embedding-3-small
vectorStore:
  provider: memory

    dimension: 1536
llm:
  provider: openai
  config:
    apiKey: ${OPENAI_API_KEY}
    model: gpt-4-turbo-preview
historyDbPath: memory.db
