unity-mcp is an open-source ai agents project by CoplayDev (CoplayDev/unity-mcp on GitHub). It has 14,772 GitHub stars and 1,537 forks, is released under the MIT license, and was last updated on GitHub on 7 October 2026.
Make sure you are on Unity 2021.3 LTS or newer (up to 6.x) and have Python 3.10+ available via uv.
In Unity's Package Manager, add the package from its Git URL (or via OpenUPM), which installs the MCP for Unity bridge into your project.
Open Window, then MCP for Unity, then Configure All Detected Clients so your AI tools can connect to the editor.
Ask your assistant something concrete - the README's example is 'Create a cube at the origin and add a Rigidbody' - and watch it appear in the editor.
A focused tool catalog covering scenes, GameObjects, assets, scripts, tests, profiling and builds, browsable in the project's tool documentation.
Claude Desktop and Code, Cursor, VS Code, Windsurf, Cline, Gemini CLI, local LLMs and more - any client that speaks MCP.
Create scenes and GameObjects, edit C# scripts and automate game-dev workflows by describing what you want.
Organize tools into groups such as vfx, animation, ui and testing to give an assistant exactly the capabilities a task needs.
Multi-instance routing supports working across more than one open Unity project.
Script edits can be validated with Roslyn, and a remote-hosted server option with authentication is available for advanced setups.
Clone the Unity MCP source if you want to develop on it; most users install the package inside Unity instead.
git clone https://github.com/CoplayDev/unity-mcp.git
cd unity-mcpIn Unity: Package Manager, Add package from git URL, using the package path from the README.
https://github.com/CoplayDev/unity-mcp.git?path=/MCPForUnity#mainAlternatively add the package with the OpenUPM CLI, then configure your clients from Window, MCP for Unity.
openupm add com.coplaydev.unity-mcpIt is a CoplayDev open-source project, sponsored and maintained by Aura; it is not affiliated with Unity Technologies.
Yes. MCP for Unity is free and MIT-licensed. Aura also offers a separate premium assistant product, which is optional.
The bridge itself needs no key; the AI assistant you connect (such as Claude or a local LLM) uses whatever account or model you already have.
Unity MCP connects external assistants you already use to the editor through the open MCP standard, rather than being a single built-in assistant tied to one provider.
Add the package in Unity's Package Manager from the git URL, run Configure All Detected Clients, and send your first prompt from your MCP client.
