Model Context Protocol (MCP) plugin to connect with Unity Editor — designed for Cursor, Claude Code, Codex, Windsurf and other IDEs
MCP Unity is a bridge between the Unity Editor and AI coding assistants through the Model Context Protocol, allowing agents to query and manipulate Unity scenes and GameObjects. Unity developers use it with assistants such as Cursor, Windsurf, Claude Code, Codex, and Copilot, and the catalogue entries provide instructions for working with it.
