Your AI builds the game.
You direct.

240+ MCP tools that let AI agents create scenes, write scripts, place assets, debug code, and run your Godot 4.x project. Not a plugin that does one thing. The whole editor, programmable.

What your AI can do

Build Scenes

Create nodes, set properties, arrange hierarchies, instance sub-scenes. Full scene tree manipulation through 26 scene and node tools. Every change goes through UndoRedo so you can always revert.

Write Code

Create and edit GDScript files, attach scripts to nodes, search across your codebase. LSP integration gives the AI autocomplete, diagnostics, hover info, and go-to-definition. DAP integration for breakpoints and stepping.

Place Everything

2D sprites, collision shapes, tilemaps. 3D meshes, materials, lights, CSG. Audio players, particle systems, navigation meshes. Shaders, themes, physics bodies. If the editor can create it, the AI can create it.

Find Assets

Search CC0 asset libraries (Poly Haven, AmbientCG, Kenney) directly from the AI. Generate 3D models and textures with AI. Manage imports and configure the asset pipeline without leaving the conversation.
