Cursor Memory MCP Server

Cursor Memory MCP Server

A persistent memory storage MCP (Model Context Protocol) server for Cursor IDE. Allows the AI assistant to remember information across sessions.

Features

• Store memories with global or project-specific scope
• Tag-based organization for easy categorization
• Search memories by content or tags
• CRUD operations - create, read, update, delete memories
• Context matching - update/delete by description, not just ID
• SQLite backend for performance and reliability
• Docker deployment for easy setup

Quick Start

1. Build and Run with Docker

docker-compose up -d --build

2. Add to Cursor MCP Configuration

Edit ~/.cursor/mcp.json:

{
  "mcpServers": {
    "cursor-memory": {
      "url": "http://localhost:8081/sse",
      "transport": "sse"
    }
  }
}

3. Restart Cursor

The memory tools will now be available to the AI assistant.

Available Tools

Usage Examples

Storing a Memory

Tell Cursor: "Remember that I prefer tabs over spaces"

The agent will:

1. Optimize the content
2. Ask for scope (global/project)
3. Suggest tags
4. Confirm before storing

Recalling Memories

Tell Cursor: "Check your memory" or "What do you remember?"

Searching Memories

Tell Cursor: "Check your memory for coding preferences"

Managing Memories

• "List all memories"
• "Delete memory #3"
• "Update the memory about indentation to prefer 4 spaces"
