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.

Basic MCP server and dependencies

Using with Cursor IDE

Open Cursor and navigate to Settings->Cursor Settings->MCP.
Click: Add new MCP server
Name: Cursor DB MCP; Type: Command
Command: <fully qualified path to>uv run --with mcp[cli] mcp run <fully qualified path to>/cursor-db-mcp-server.py

Installing MCP servers for Claude Desktop

Add this to your claude_desktop_config.json file

    "cursor-db-mcp": {
      "command": "<fully qualified path to >/uv",
      "args": [
        "run",
        "--with",
        "mcp[cli]",
        "mcp",
        "run",
        "<fully qualified path to >/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

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.
This was written on a Mac. YMMV with other OS
