Simple Memory MCP Server

A simplified MCP (Memory Control Protocol) server for Cursor IDE that focuses solely on memory storage and retrieval using Neo4j.

Features

• Simple memory storage and retrieval
• Real-time memory updates via SSE
• Neo4j backend for persistent storage
• JSON-RPC 2.0 compliant

Prerequisites

• Python 3.8+
• Neo4j database running locally
• Cursor IDE

Installation

1. Install dependencies:

pip install -r requirements.txt

2. Start Neo4j: Make sure Neo4j is running on:

• HTTP port: 7476
• Bolt port: 7687
• Username: neo4j
• Password: troykailey

3. Run the server:

python simple_mcp_server.py

Cursor IDE Configuration

1. Open Cursor Settings
2. Go to Features > MCP
3. Add new MCP server with:
   • Type: SSE
   • URL: http://localhost:8003/sse

Usage

The server provides two main endpoints:

1. /sse - Server-Sent Events endpoint for real-time memory updates
2. /memory - POST endpoint for storing new memories

The server will automatically send:

• Initial capabilities message
• Memory updates every 5 seconds
• Error messages if something goes wrong

Simplified Architecture

This version removes complexity by:

• Focusing only on memory functionality
• Using a simpler Neo4j schema
• Removing unnecessary endpoints
• Simplifying the JSON-RPC messages

Troubleshooting

If you encounter issues:

1. Check Neo4j is running and accessible
2. Verify the ports (8003 for MCP, 7687 for Neo4j)
3. Check Cursor's MCP configuration
4. Look for error messages in the server logs
