# MCP for Unity by Coplay — guide skill for 3D scenes

> **For AI agents:** find the right skill in one call — `curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>"` returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add `.md` to its path. Before generating anything, show the person the options on the how-to page. From a terminal: `curl -fsSL https://varg.ai/install | sh` installs the vargai CLI (https://varg.ai/how-to/cli.md): `vargai search` and `vargai install <slug>` with no key, every varg model after `vargai login`.

Open-source bridge from Claude, Codex, Cursor and other MCP clients to the Unity Editor: scenes, scripts, assets, tests.

## What it does

MCP for Unity connects AI assistants to a running Unity Editor (2021.3 LTS to 6.x) through a Unity package and a Python server run with uv. About 50 tool entry points create scenes and GameObjects, edit C# scripts, manage assets, packages, VFX, animation and UI, run tests, profile and build, and its `unity-mcp-orchestrator` skill teaches the agent a resource-first workflow. One menu item in Unity configures every detected client (or install with `openupm add com.coplaydev.unity-mcp`). Free and MIT, maintained by Coplay (Aura); not affiliated with Unity Technologies, whose own Claude Code plugin is under the Unity Companion License.

## Use when

- drive the Unity Editor from Claude Code, Codex, Cursor or VS Code
- create scenes, GameObjects and C# scripts by prompt
- run Unity tests, profiling and builds from an agent
- build a Unity scene to capture for a game trailer

## Not for

- Unreal, Godot or Roblox: see unreal-engine-mcp, godot-mcp or roblox-studio-mcp
- Projects without a backup: the tools edit live assets

## Install

- Any MCP client: `Unity → Package Manager → Add from git URL: https://github.com/CoplayDev/unity-mcp.git?path=/MCPForUnity#main && Window → MCP for Unity → Configure All Detected Clients`
- Any agent, with the vargai CLI: `vargai install unity-mcp`
