Cursor DB MCP Server

A Model Context Protocol (MCP) server for accessing Cursor IDE's SQLite databases. This server allows AI assistants to explore and interact with Cursor's project data, chat history, and composer information.

Installation

Easy Installation

Use the provided installation script to install all dependencies:

python install.py

This script will install:

• Basic MCP server and dependencies

Using with Cursor IDE

1. Open Cursor and navigate to Settings->Cursor Settings->MCP.
2. Click: Add new MCP server
3. Name: Cursor DB MCP; Type: Command
4. Command: \uv run --with mcp[cli] mcp run /cursor-db-mcp-server.py

!Cursor DB MCP

Now you can ask questions about the database or retrieve info about historical chats.

Using with Claude Desktop

Installing MCP servers for Claude Desktop

Add this to your claude_desktop_config.json file

    "cursor-db-mcp": {
      "command": "/uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "/cursor-db-mcp-server.py"
      ]
    }

Available Resources

• cursor://projects - List all available Cursor projects
• cursor://projects/detailed - List projects with detailed information
• cursor://projects/{project_name}/chat - Get chat data for a specific project
• cursor://projects/{project_name}/composers - Get composer IDs for a specific project
• cursor://composers/{composer_id} - Get data for a specific composer

Available Tools

• query_table - Query a specific table in a project's database
• refresh_databases - Refresh the list of database paths

How It Works

The server scans your Cursor installation directory to find project databases (state.vscdb files). It then exposes these databases through MCP resources and tools, allowing AI assistants to query and analyze the data.

Notes

1. Cursor stores AI conversations in different places. Increasingly, chats are stored as "composerData" under globalStorage/state.vscdb. If you don't get results when asking about chats for recent projects, try asking for composers.
2. This was written on a Mac. YMMV with other OS
