Godot MCP

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. AI reads, writes, and manipulates your scenes, scripts, nodes, and project settings directly.

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

Inside the Godot editor, click the AssetLib tab at the top → search "mcp" → find "Godot AI Assistant tools MCP" → Install.

Then go to Project → Project Settings → Plugins and enable the Godot MCP plugin.

2. Add the server config to your AI client

Claude Desktop — Settings → Developer → Edit Config → open the config file and paste:

Mac / Linux:

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

Windows:

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

Cursor — Settings → MCP → Add Server:

Mac / Linux:

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

Windows:

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

Claude Code — run in terminal:

claude mcp add godot -- npx -y godot-mcp-server

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

3. Restart your AI client

Close and reopen Claude Desktop / Cursor / your client so it picks up the new config.

4. Restart your Godot project

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

What Can It Do?

Interactive Visualizer

Run map_project and get a browser-based 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 <img width="1710" height="1107" alt="image" src="https://github.com/user-attachments/assets/a9faf163-8b8b-43da-93ec-c7a651e8ac60" />

Limitations

AI cannot create 100% of a game by itself — it struggles with complex UI layouts, compositing scenes, and some node property manipulation. It's still in active development, so feedback is very welcome!

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 is still limited in Godot knowledge — it can't create 100% of the game alone, but it can help debug, write scripts, and tag along for the journey

Development

To build from source instead of using npm:

cd mcp-server
npm install
npm run build

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

Release notes

Narrative write-ups of each release live in release-notes/ (starting with v0.5.0). For the full change history, see CHANGELOG.md.
