01

Install the plugin

Two ways to get the plugin into your project — pick whichever fits your workflow.

Recommended

CLI

Install via the unreal-mcp-cli tool on npm. Works today against any UE 5.5+ C++ project.

1Install the CLI

Install unreal-mcp-cli globally from npm.

npm install -g unreal-mcp-cli
2Install the plugin

Install the Unreal-MCP plugin into your project.

unreal-mcp-cli install-plugin ./YourProject
3Authorize

Log in so the plugin can connect through ai-game.dev.

unreal-mcp-cli login ./YourProject
4Open the project

Open the project in the Unreal Editor.

unreal-mcp-cli open ./YourProject
Coming soon

Fab / Epic Marketplace

Install Unreal-MCP from Fab via the Epic Games Launcher — precompiled, zero build. Not yet live on Fab; until it lands, use the CLI option, which works today.

1Install from Fab

Install Unreal-MCP from Fab via the Epic Games Launcher.

2Enable the plugin

In the editor: Edit → Plugins, find Unreal-MCP and enable it.

3Open the project

Reopen your project — the plugin is precompiled, so there is nothing to build.

02

Connect

Run through the hosted cloud endpoint, or point at your own server.

Cloud

Default

Connect through ai-game.dev using the device-code OAuth flow — no tokens to copy by hand. From the AI Game Developer window choose Cloud, click Authorize, and approve the device code in your browser. Works across firewalls and gives you usage analytics. This is the default and what we recommend for most users.

Custom

Prefer to run everything locally? Point the plugin at your own gamedev-mcp-server instance instead of the hosted endpoint. Your AI client then talks straight to your machine. Client-by-client config snippets live on the MCP endpoint page.

Need client config snippets (Claude, Cursor, Copilot, Gemini and more)? See the MCP endpoint page →

03

First run

Open the window, authorize, and try your first prompt.

  1. Open the AI Game Developer window from the editor Tools menu.
  2. Choose Cloud and click Authorize to complete the device-code flow.
  3. Wait for the connection to go green, then connect your AI client.
  4. Try a prompt like the one below and watch it act in the editor.
Example prompt
Create a new Actor blueprint with a static mesh cube and place three of them in the level.
