I have built this mini demo-game with an MCP tool for godot i am developing, just one prompt and about 15 minutes of running.

I'm working (actually i have alredy implemented 35 tools) in this MCP server which allows to connects coding agents to godot, and enables the agent to do real things, it can, such as a human de, run the game, test it, take screenshots, move the camera, interact with the ui, and a lot of things, i am testing this with many project and many test, and i think it works really well, also for diagnostic case, to take an alredy built in game, and it can understand quickly the entire game loop, the scenes, etc.
