Godot Catalyst

Godot Catalyst gives AI agents real control of the Godot 4 editor. 240+ MCP tools covering scenes, nodes, scripts, resources, animation, physics, audio, shaders, particles, tilemaps, debugging, profiling, and asset search. Works with Claude Code, Cursor, Windsurf, Copilot, Cline, and any MCP client.

What this looks like in practice

Ask Claude to add a double-jump and it opens your PlayerController, reads the existing logic, writes the change, connects the signals, and plays the scene to verify. Ask it to find a CC0 stone texture that matches your mossy wall and it searches Poly Haven, AmbientCG, and Kenney, downloads the match, and sets up the material. Ask why your dungeon drops to 30 fps and it runs the profiler, identifies the bottleneck node, and tells you the fix.

What's in it

Full editor surface: scene tree, node CRUD, script attach/edit, resources, signals, undo/redo, selection. 2D and 3D helpers for collision, lighting, environment, cameras, parallax. Animation tracks and AnimationTree. Physics, navigation baking, raycasts. Shaders with live parameters. Themes, particles, tilemaps with bulk fill.

Past the editor: LSP for diagnostics, completion, hover, rename, and format. DAP for breakpoint debugging. Offline TSCN/TRES parsing so agents can reason about your project without Godot running. Offline class reference search. Input simulation (keyboard, mouse, touch, gamepad, record and replay). Performance profiling with bottleneck detection. Visual testing with pixel-diff screenshots. AI 3D model generation via Meshy and Tripo. Convention enforcement with auto-fix. Architecture analysis and dead code detection.

Install

Node 18+ and Godot 4.x required.

npx godot-catalyst --install-addon /path/to/your/project

Enable the plugin in Project Settings > Plugins. Point your MCP client at npx godot-catalyst with GODOT_PROJECT_PATH set to your project.

Trial and activation

First install starts a 7-day free trial. No account. After purchase, copy your download key from your itch library and run:

npx godot-catalyst --activate-itch <your-download-key>

One license, three machines. Buy once, own it.

Tool modes

Copilot Chat and some clients choke on 240+ tools. Set GODOT_TOOL_MODE=lite (80 tools) or minimal (30 tools) to fit. cli mode runs offline with no Godot needed.

Limitations

Godot 4.x only, not 3.x. LSP and DAP need Language Server and Debug Adapter enabled in Editor Settings. You still write the prompts — this is a tool for agents, not a game generator.
