Godot MCP Server

Give your AI assistant full access to the Godot editor.

Build games faster with Claude, Cursor, or any MCP-compatible AI — no copy-pasting, no context switching. The AI reads, writes, and manipulates your scenes, scripts, nodes, and project settings directly inside the running Godot editor.

Quick Start

0. Install Node.js (one-time setup)

Download and run the installer from nodejs.org (LTS version). It's a standard installer — no terminal needed.

1. Install the Godot plugin

No cloning or building required — runs directly via npx.

Claude Desktop — edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "godot": {
      "command": "npx",
      "args": ["-y", "godot-mcp-server"]
    }
  }
}

Cursor — add to MCP settings (Settings → MCP → Add Server):

{
  "mcpServers": {
    "godot": {
      "command": "npx",
      "args": ["-y", "godot-mcp-server"]
    }
  }
}

Works with any MCP-compatible client (Claude Code, Cline, Windsurf, etc.)

2. Install the Godot plugin

Copy the addons/godot_mcp/ folder from the GitHub repo into your Godot project's addons/ directory. Then enable it: Project → Project Settings → Plugins → Godot MCP → Enable.

Or install directly from the Godot Asset Library: AssetLib → search "Godot MCP" → Install.

3. Connect

Restart your Godot project. Check the top-right corner of the editor — you should see MCP Connected in green. You're ready to go.

What Can It Do?

32 Tools Across 6 Categories

Category	Tools	Examples
File Operations	4	Browse directories, read files, search project, create scripts
Scene Operations	11	Create scenes, add/remove/move nodes, set properties, attach scripts, assign collision shapes and textures
Script Operations	6	Apply code edits, validate syntax, rename/move files with reference updates
Project Tools	9	Read project settings, input map, collision layers, console errors, scene tree dumps
Asset Generation	1	Generate 2D sprites from SVG
Visualization	1	Interactive browser-based project map

Interactive Visualizer

Run map_project and get a browser-based project explorer at localhost:6510:

• Force-directed graph of all scripts and their relationships
• Click any script to see variables, functions, signals, and connections
• Edit code directly in the visualizer — changes sync to Godot in real time
• Scene view with node property editing
• Find usages before refactoring

The MCP server connects to the Godot editor via WebSocket through the Godot plugin. The AI never guesses at your project structure — it reads live state directly from the running editor.

Current Limitations

• Local only — runs on localhost, no remote connections
• Single connection — one Godot instance at a time
• No undo — changes save directly (use version control)
• AI has limited Godot knowledge — it can help debug, write scripts, and build scenes, but can't create a complete game without guidance

Build From Source

git clone https://github.com/tomyud1/godot-mcp
cd godot-mcp/mcp-server
npm install
npm run build

Then point your AI client at mcp-server/dist/index.js instead of using npx.
