mem0 MCP Server

A TypeScript implementation of the Model Context Protocol (MCP) server for mem0, providing memory stream functionality with Mem0 integration.

Features

• Create memory streams with Mem0 integration
• Append content to memory streams
• Search memories using Mem0’s semantic search
• Read from memory streams
• Resource-based access to memory streams
• Delete memory streams

Prerequisites

1. Node.js and npm installed
2. Mem0 API key (get one from mem0.ai)

Installation

npm install

Configuration

Set your Mem0 API key as an environment variable:

export MEM0_API_KEY=your-api-key-here

Building

npm run build

Running the Server

npm start

Testing

Run the test client to verify server functionality:

npm test

API

Tools

1. create-memory-stream

   • Parameters:
     • name: string
     • initialContent: string (optional)
     • userId: string (optional) - Mem0 user ID
     • agentId: string (optional) - Mem0 agent ID
   • Returns: Stream ID and metadata

2. append-to-stream

   • Parameters:
     • streamId: string
     • content: string
     • role: “user” | “assistant” (optional)
   • Returns: Success confirmation

3. search-memories

   • Parameters:
     • query: string
     • userId: string
     • agentId: string (optional)
     • threshold: number (optional)
   • Returns: Search results from Mem0

4. read-stream

   • Parameters:
     • streamId: string
     • startIndex: number (optional)
     • endIndex: number (optional)
   • Returns: Stream content

5. delete-stream

   • Parameters:
     • streamId: string
   • Returns: Deletion confirmation

Resources

• memory://{streamId} - Access memory stream content directly
• memory:// - List all memory streams

Development

The server is implemented using the MCP TypeScript SDK and provides integration with Mem0 for persistent memory storage and semantic search. To extend the implementation:

1. Add more Mem0 features (e.g., memory tagging, metadata)
2. Implement proper error handling
3. Add authentication and authorization
4. Add additional memory operations
