Cursor Desktop

Use Cursor Desktop with NeoStack AI through MCP.

Cursor Desktop connects to NeoStack AI through the NeoStack bridge, a small stdio MCP binary. Requires NeoStack AI plugin 3.1.8 or newer.

Step 1: download the bridge

On macOS/Linux, run chmod +x on it once.

Step 2: configure

Create .cursor/mcp.json in your Unreal project folder:

{
  "mcpServers": {
    "unreal": {
      "command": "/path/to/neostack-bridge-macos-arm64"
    }
  }
}

Use the path to the binary you downloaded. For global access, use ~/.cursor/mcp.json instead.

There are no ports, tokens, or URLs to configure. The bridge finds the running editor and follows restarts.

Verify

1. Start Unreal Editor with NeoStack AI enabled.
2. Restart Cursor or reload the window.
3. Open Cursor chat and check that Unreal Editor tools are available.

Notes

• Cursor may ask you to approve the MCP server before tools appear.
• If several editors are open, ask the agent to “list unreal projects” and “select” one, or set the NEOSTACK_PROJECT_DIR env var in the server config.
