Install

openupm add com.coplaydev.unity-mcp

OpenUPM alternative, run in the Unity project folder.

This is third-party code. Review the repository files before installing.

What it does

MCP for Unity links the Unity Editor to an agent: a package inside Unity receives commands and a Python server exposes them to the client as MCP tools. The agent can create scenes and game objects, add components, edit C# scripts, manage assets, run tests, profile and build the project. Tools are grouped, for example for VFX, animation and UI. It supports several open Unity instances and a remote server with auth.

Who it is for. For Unity game and interactive app developers who want an agent to handle routine editor work.

Good fit when

  • You want to prototype a scene from a text description quickly
  • You need bulk changes to objects, components or assets
  • The agent should run tests and builds itself after editing scripts

Not a fit when

  • The project uses Unreal, Godot or another engine
  • Your Unity version is older than 2021.3 LTS

Example request

Create a cube at the origin and add a Rigidbody to it

Limitations

Requires Unity 2021.3 LTS through 6.x and Python 3.10+ via uv. The editor must be open. The project is not affiliated with Unity Technologies. The agent changes scenes and scripts directly, so work under version control.

How to disable. Remove the MCP for Unity package in Package Manager and delete the server from the client's MCP config.

README in short

The README briefly lists capabilities and gives three steps: add the package to Unity via git URL or OpenUPM, configure clients from the menu and send a first prompt. The full tool catalog, tool groups, multi-instance routing and remote server are in the docs. MIT licensed.

FAQ

Do I have to add the server to the client by hand?

Usually not: the package menu has an item that configures detected clients automatically.

Is it paid?

No, it is free under MIT. The paid Aura assistant from the same team is a separate product.
