Cursor Filesystem create_directory

Add Filesystem to Cursor

1. 01

   Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "server-filesystem": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-filesystem"
      ]
    }
  }
}

2. 02

   Save the file and restart Cursor.

3. 03

   Ask for something create_directory does. Cursor lists the server's tools on connect and calls create_directory itself — you do not invoke it by name.

4. 04

   If nothing happens, check the server is running and that Filesystem's identifier in your config matches the one above exactly.

Use .cursor/mcp.json in a project root instead to scope it to that project. Cursor merges both. Cursor docs
