Overview
What is Unity MCP Integration?
Unity MCP Integration is a package that connects the Model Context Protocol (MCP) to the Unity Editor, enabling AI assistants to access real-time information about project scenes, execute C# code directly in the Editor, monitor logs, and control play mode. It is built for Unity developers who want to leverage AI within their Unity workflow.
How to use Unity MCP Integration?
Install the Unity package via the Package Manager using the Git URL or import the custom package. Then, navigate to the mcpServer directory, run npm install and node build/index.js to start the MCP server, or add the server configuration to your MCP Host. Use the MCP Debug window (Window > MCP Debug) to monitor the connection and test features.
