## Overview

MCP for Unity (CoplayDev/unity-mcp) bridges AI assistants such as Claude, Codex, VS Code and local LLMs with the Unity Editor through the Model Context Protocol.

From plain-language prompts, an agent can create scenes and GameObjects, edit C# scripts, manage assets, run tests, profile and build. It exposes about 50 focused tool entrypoints and supports Unity 2021.3 LTS through 6.x.

## Key features

- Create scenes and GameObjects from prompts
- Edit C# scripts in your project
- Manage assets
- Run tests, profile and build
- Auto-configure detected MCP clients

## Use it for

- Have a coding agent set up a Unity scene
- Automate repetitive editor work
- Let an agent fix scripts and rerun tests

## Pricing

MCP for Unity is free and open source under MIT. Your AI client or model is billed separately.

In Unity's Package Manager, add the package from the GitHub git URL, then use Window > MCP for Unity > Configure All Detected Clients.
