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.

Now on the Godot Asset Store as Godlink MCP. If it helps you, please leave a review there. It's the main way other Godot developers find it.

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

Godot 4.7 and newer: inside the Godot editor, click the Asset Store tab at the top → search "Godlink" → find "Godlink MCP" → Install. (Store page)

Godot 4.6 and older: click the AssetLib tab instead → search "mcp" → find "Godot AI Assistant tools MCP" → Install.

Manual install: copy the addons/godot_mcp/ folder from this repo into your project's addons/ folder.

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 — once your AI client is running you should see MCP: Agent Active in green. You're ready to go.

If it shows MCP: No Agent in orange, Godot found the server but no AI client is using it yet. Restart your AI client. MCP: Disconnected in red means the server isn't running. Check that Node.js is installed and the config from step 2 is saved.

What Can It Do?

69 Tools Across 7 Categories

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

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
• One Godot editor at a time — multiple AI clients can connect concurrently, but they all share a single Godot instance
• Ctrl+Z does not reach AI changes — the plugin writes to disk rather than the editor's live tree, so Godot's native undo has nothing to revert. Use the mcp_undo tool instead (ask the agent to undo).
• 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.
