MCP Unity is an implementation of the Model Context Protocol for Unity Editor, allowing AI assistants to interact with your Unity projects. This package provides a bridge between Unity and a Node.js server that implements the MCP protocol, enabling AI agents like Cursor, Windsurf, Claude Code, Codex CLI, GitHub Copilot, Google Antigravity, and OpenCode to execute operations within the Unity Editor.
Features
IDE Integration - Package Cache Access
MCP Unity provides automatic integration with VSCode-like IDEs (Visual Studio Code, Cursor, Windsurf, Google Antigravity) by adding the Unity Library/PackedCache folder to your workspace. This feature:
- Improves code intelligence for Unity packages
- Enables better autocompletion and type information for Unity packages
- Helps AI coding assistants understand your project's dependencies
MCP Server Tools
The following tools are available for manipulating and querying Unity scenes and GameObjects via MCP:
