Unity MCP is a package that connects the Unity Editor to an AI agent through the Model Context Protocol. Once installed, an agent can read the current scene, add objects and read the errors shown in the Console, so a developer can ask for changes in plain language instead of clicking through the editor. It is documented as working with Claude Code, Claude Desktop, Cursor, Codex, the Gemini CLI and VS Code.
There are two installation routes. The first needs no command line: the package is added in Unity through the Package Manager using a Git URL, then Claude Desktop is connected using its extension format, which is distributed for Windows and macOS. The second installs a command line tool so the Editor can be driven from Claude Code, Cursor, Codex and similar clients, and it is the route for Linux. Projects managed with the VRChat Creator Companion or ALCOM can add the package from a VPM repository, which avoids needing Git.
Requirements are Unity Editor 2022.3 or newer and Git for the standard Package Manager route. The project has to stay open in the Editor while the agent is used. A Preferences panel shows when the server is listening, and the server starts automatically when the project opens. The documentation is available in English, Japanese and Vietnamese.
It is aimed at Unity developers who want an AI assistant working inside their live project. The site publishes no pricing and the package is installed directly from its public repository.
