godot-ai
Godot AI connects MCP clients such as Claude Code, Codex and Antigravity directly to a running Godot editor. The README says more than 120 operations across about 39 MCP tools let an assistant build scenes, edit nodes, search the project and run the scene test suite; the full list is in docs/TOOLS.md. Example prompts include showing the scene hierarchy, creating a Camera3D under a node and building a voxel block-world game, and the README shows a UI demo built in about two hours with no hand-written code.
It has three layers: an editor plugin that uses Godot's EditorInterface and SceneTree APIs, a Python FastMCP server on port 8000 and a WebSocket link on port 9500. Requirements are Godot 4.3 or newer (4.4+ recommended), uv for the Python server and an MCP client. Install by copying `addons/godot_ai` into your project or from the Godot Asset Library (which may lag behind GitHub), enable the plugin, then use the editor's dock to auto-configure a client; many clients are supported and manual snippets are provided for the rest. The server URL is `http://127.0.0.1:8000/mcp`. It is MIT licensed.
