Unity Biome MCP server

This is a helper that connects an AI assistant to the Unity Editor, the program where you build games. You can ask your AI in plain words to inspect a scene, add a component, or run a playtest, and it will do it inside Unity. It is handy for game developers and anyone who works in Unity and wants to skip a lot of clicking.

What this MCP server does

You type a request in your AI app, like asking it to check your scene or add an object. The AI sends that request to this helper program. The helper talks to a small add-on inside Unity, which is the part that actually reads or changes your project. Then the result comes back to you in the chat as a list, a summary, or a note about what changed.

What you can do with it

• Inspect your active scene and list the objects in it
• Create GameObjects and add components like Rigidbody or BoxCollider
• Change properties such as position, mass, or material settings
• Work with materials, shaders, and Shader Graph
• Run playtests and check that things behave as expected
• Capture the Game View and compare it with a saved baseline
• Summarize what changed in the scene since a checkpoint

Try asking your AI

• “Read the active Unity scene hierarchy at depth 2 and summarize its root objects.”
• “Create a player object, add a Rigidbody, and place it at the scene origin.”
• “Find enemies without colliders and add a BoxCollider to each.”
• “Run a playtest that moves the player to the door and verifies that the score increases.”

What it gives back to you

You get answers in your chat, like a list of scene objects, a summary of what the AI found, or a report of the changes it made. For playtests, you get the results of the checks and any captured images. If something fails, you get an error message you can act on.
