How to Set Up and Use Unity MCP Server
Unity MCP Server provides over 268 tools that connect AI assistants (Claude, Cursor, Codex, VS Code, and local LLMs) directly to the Unity Editor and Unity Hub for AI-assisted game development. It enables managing scenes, GameObjects, components, scripts, assets, builds, terrain, physics, NavMesh, animations, Shader Graph, profiling, and more — all through natural-language commands from your AI client. Game developers use it to automate repetitive Unity workflows, generate boilerplate code, and iterate on scenes without switching windows.
Prerequisites
- Unity Editor installed (2021 LTS or newer recommended)
- Python 3.10+ installed on your system
- Claude Desktop, Cursor, VS Code, or another MCP-compatible AI client
- Git or Unity Package Manager access to install the package
Install the Unity package via Package Manager
Open Unity, go to Window > Package Manager, click the + button, choose 'Add package from git URL', and paste the repository URL.
https://github.com/CoplayDev/unity-mcp.git?path=/MCPForUnity#mainConfigure detected AI clients from Unity
After installation, open Window > MCP for Unity > Configure All Detected Clients. The tool auto-detects installed AI clients and writes the necessary config entries.
Add the MCP server to your AI client manually (if needed)
If auto-detection does not configure your client, add the server block manually to your Claude Desktop or Cursor config.
{
"mcpServers": {
"unity-mcp-server": {
"command": "npx",
"args": ["-y", "unity-mcp-server"]
}
}
}Verify the connection in Unity
With both Unity Editor and your AI client running, check the MCP for Unity panel (Window > MCP for Unity) to confirm the client connection is active.
Enable beta features (optional)
For access to beta tools including advanced VFX, animation, and UI tool groups, change the package URL to use the #beta branch instead of #main.

}Prompts to try
Use these prompts in Claude or Cursor with the Unity MCP Server connected and Unity Editor open.
- "Create a red, blue, and yellow cube in the current scene"
- "Add a Rigidbody component to the Player GameObject"
- "Create a new C# script called PlayerMovement and attach it to the Player"
- "Build the project for Windows x64 and save to the Builds folder"
- "List all GameObjects in the current scene"Troubleshooting Unity MCP Server
Package Manager fails to fetch the git URL
Ensure Git is installed and accessible on your PATH (git --version). Unity Package Manager uses the system Git binary. Also check that your firewall allows connections to github.com.
AI client shows the server as disconnected
Ensure Unity Editor is open and the MCP for Unity package is loaded — the server only runs while Unity is active. Restart both Unity and your AI client and re-check the MCP for Unity panel for connection status.
Python 3.10+ not found error during server startup
Install Python 3.10 or newer and ensure it is on your PATH (python3 --version). On macOS, install via Homebrew: brew install [email protected]. The server requires Python to bridge the Unity Editor communication.
