Install the plugin

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

Recommended

CLI

Install via the unity-mcp-cli tool. Nothing to download by hand — run the commands in your terminal.

1Install the CLI

Install unity-mcp-cli globally from npm.

npm install -g unity-mcp-cli
2Install Unity (optional)

Install the Unity Editor using the CLI. Skip if already installed.

unity-mcp-cli install-unity 6000.3.9f1
3Create Unity project (optional)

Create a new Unity project, or use an existing one.

unity-mcp-cli create-project ./MyUnityProject
4Install plugin

Install the Unity MCP package into your project.

unity-mcp-cli install-plugin ./MyUnityProject
5Open Unity project

Open the project in the Unity Editor.

unity-mcp-cli open ./MyUnityProject

Installer

Download the .unitypackage installer and import it directly into your Unity project — a one-time drop-in install.

Download .unitypackage
1Install Unity (optional)

Download Unity Hub and install any Unity 2022.3 LTS or newer Editor. Skip if already installed.

2Create Unity project (optional)

Create a new Unity project with Unity Hub, or use an existing one.

3Download installer

Use the Download .unitypackage button above to grab AI-Game-Dev-Installer.unitypackage.

4Import the package

In Unity: Assets → Import Package → Custom Package… and pick the downloaded file.

Prefer a package registry? Add it via OpenUPM instead: openupm add com.ivanmurzak.unity.mcp. See the Unity plugin setup guide for the full deep dive.

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 project in the Unity Editor, then go to Window → AI Game Developer.
  2. In the panel, choose Cloud and click Authorize to complete the device-code flow.
  3. Wait for the status pill to read Ready (green), then connect your AI client.
  4. Try a prompt like the one below from your AI client and watch it act in the Editor.
Example prompt
Create a new scene with a directional light and a rotating cube, then enter Play mode.
