Godot AI
hi-godot/godot-ai
MCP server and editor plugin that lets AI agents like Hermes Agent build and edit Godot projects
Godot AI is an MCP server and Godot editor plugin that connects MCP clients, including Hermes Agent, to a live Godot editor. It gives assistants 46 tools and 120+ operations for building scenes, editing nodes and scripts, and configuring UI, materials, animation and more.
What Godot AI does
Godot AI runs as an add-on inside the Godot editor. When the plugin is enabled in Project Settings, it starts an MCP server and shows connection status in a Godot AI dock. MCP clients such as Claude Code, Claude Desktop, Codex, Cursor, VS Code and Hermes Agent can then drive the open editor through 46 tools and more than 120 operations, covering scenes, nodes, scripts, signals, UI, materials, animation, particles, cameras and environments.
GDScript is fully supported: scripts written through the tools are parse-validated, hot-reloaded, attached and outlined. C# is text-only, meaning the tools write .cs files and outline symbols but do not build .NET or report compiler errors. The dock has a Configure button for each detected client and a Configure all option, and version 4 connects clients with godot-ai attach over stdio instead of a bare HTTP endpoint. Updates are offered from the dock, with a one-click migration from the final v3 release.
