Gerty for Unity lets Claude Code control your Unity Editor. Nearly anything you can do in Unity, Gerty lets Claude do directly. It's the missing piece to make Unity + Claude magical.Meet Gerty, your assistant's...assistant.Claude Code is brilliant at writing code, but when it comes to actually making things happen inside Unity, you're left doing all the work. Gerty is the friendly helper on the inside that provides the missing link so Claude + Unity feels like magic.The ProblemYou ask Claude to "set up a player prefab with a collider," but Claude is stuck. It can't see your scene. It can't click buttons. Best case, it makes a README file telling you how to do it. But that's a lot of busy work and slows down the whole process. You need an assistant on the inside of Unity for your coding agent.The SolutionGerty lives in your Unity Editor, ready to do Claude's bidding. Claude says "find all objects missing colliders," and Gerty finds them. Claude says "set up the lighting for a night scene," and Gerty handles it. Simple as that.What Gerty Does• Sees your whole scene: Every object, every component, every material. Gerty knows what's in your project and can describe it to Claude.• Takes action directly: Create objects, move things around, change colors, add components; Gerty does it right in your Editor.• Sets itself up: No config files to edit. No tokens to copy. Install Gerty, open your project, and you're ready to go.If you've ever thought, "Why can't Claude just do this for me in Unity instead of me having to do it myself?" then this is the tool you need!Ready in a Snap1. Import Gerty from the Asset Store2. Open your Unity project, Gerty starts automatically3. Run `claude` in your project folder4. Start making your game!Things You Can Just... Ask• "Find all the lights in my scene and make them 50% brighter"• "Create a simple enemy that follows the player"• "What objects have a Rigidbody but no collider?"• "Organize my hierarchy — group all the environment objects"• "Make a simple day/night cycle for this scene"• "Write a PlayerController with WASD movement and jumping"• "Create a level layout using grayboxes for my FPS shooter"FAQHow does it work?Gerty uses several features supported by Claude Code including an MCP Server, an Agent, and a Skill to accomplish its goals. It also features a system which helps index the objects in your Scene and Assets in your project to help Claude better understand them, so it can reason about the entire project and make smart choices.Do I need an API key or separate subscription?Nope! Gerty works with your existing Claude Code subscription. No extra LLM usage, no API keys to manage, no per-token billing. You're just using Claude Code like you already were, but now it has a helper to let it do even more directly without your intervention.What can Gerty actually do in Unity?Anything you can do in the Unity Editor. Create GameObjects, layout scenes, create prefabs, setup Animators, add components, write scripts, set up lighting, configure physics — all of it. You can literally code entire games without touching Unity yourself.Is it safe?Gerty includes safeguards to prevent dangerous operations, but we always recommend using version control. Claude can make mistakes just like any assistant: having a backup means you can always roll back.RequirementsUnity 2023.1 or newerClaude Code CLI (https://docs.anthropic.com/en/docs/claude-code) with an active Claude subscription or API key setupHas been tested to work on Windows and Mac. Should work on Linux as well but untested.SupportQuestions? Email us at team@gerty.devClaude Code was used to help create this tool. In addition, the Sample Scene that is included in the package was completely created by Claude Code using Gerty.
