One free add-on gives Cloud Code and Codex 79 game production skills for 12 engines, from Godo and Unity to Roblox. You describe the game, and it loads the right 2 or 3 skills before the agent writes any code.
It's #1 on the list of 10 free GitHub projects for building games with AI, selected by AI educator Brendan Jowett. The list has more than 3,600 bookmarks in X.
The other AI choices:.
1. Unity MCP allows your agent to create scenes, add objects and run tests within the Unity editor.
2. Godo MCP allows it to run Godo, run your project and read the errors. Adding it to Claude's code requires one command.
3. TripoSR turns a single image into a 3D model.
The remaining six are free code libraries for 3D web games: physics, visual effects, character behavior, and online multiplayer.
