Godot MCP - Full Control

A comprehensive Model Context Protocol (MCP) server that gives AI assistants full control over the Godot game engine. 149 tools spanning networking, 3D/2D rendering, UI controls, audio effects, animation trees, file I/O, runtime code execution, property inspection, scene manipulation, signal management, physics, project creation, and more.

Acknowledgments

This project is built upon and extends godot-mcp by Solomon Elias (Coding-Solo). The original project provided the foundational architecture including the TypeScript MCP server, headless GDScript operations system, and TCP-based runtime interaction server. Thank you for making this possible with your excellent open-source work!

Requirements

• Godot Engine (4.x recommended, 4.4+ for UID features)
• Node.js >= 18.0.0
• An AI assistant that supports MCP (Claude Code, Cline, Cursor, etc.)

Installation

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

Configuration

Claude Code

Add to your Claude Code MCP settings:

{
  "mcpServers": {
    "godot": {
      "command": "node",
      "args": ["/absolute/path/to/godot-mcp/build/index.js"],
      "env": {
        "GODOT_PATH": "/path/to/godot",
        "DEBUG": "true"
      }
    }
  }
}

Cline (VS Code)

Add to your Cline MCP settings (cline_mcp_settings.json):

{
  "mcpServers": {
    "godot": {
      "command": "node",
      "args": ["/absolute/path/to/godot-mcp/build/index.js"],
      "disabled": false
    }
  }
}

Cursor

Create .cursor/mcp.json in your project:

{
  "mcpServers": {
    "godot": {
      "command": "node",
      "args": ["/absolute/path/to/godot-mcp/build/index.js"]
    }
  }
}

Runtime Tools Setup

To use the game_* runtime tools, your Godot project needs the MCP interaction server autoload. Copy build/scripts/mcp_interaction_server.gd to your project and register it as an autoload:

1. Copy build/scripts/mcp_interaction_server.gd to your project's scripts folder
2. In Godot: Project > Project Settings > Autoload
3. Add the script with the name McpInteractionServer

The server listens on 127.0.0.1:9090 and accepts JSON commands over TCP when the game is running.

Environment Variables

Architecture

The server uses two communication channels:

1. Headless CLI - For operations that don't need a running game (scene reading, modification, resource creation). Runs Godot with --headless --script godot_operations.gd <operation> <json_params>.

2. TCP Socket - For runtime interaction with a running game. The mcp_interaction_server.gd autoload listens on port 9090 and processes JSON commands sent by the TypeScript MCP server.

Source layout

Testing

The project uses Vitest with 390 tests across 3 files:

npm test          # run once
npm run test:watch  # watch mode

Example Prompts

"Run my Godot project and check for errors"

"Eval this in my running game: return get_tree().current_scene.name"

"Get the player's position in the running game"

"Set the player's health to 100"

"Read the test_level.tscn scene and show me the node tree"

"Change the player's speed property in the player.tscn scene file"

"List all .gd files in my project"

"Connect the enemy's 'died' signal to the game manager's 'on_enemy_died' method"

"Tween the camera's position to (0, 10, -5) over 2 seconds with ease-out"

"Get performance metrics - what's my FPS and draw call count?"

"Pause the game and take a screenshot"

"Find all CharacterBody3D nodes in the scene"

"Create a new Godot project called 'MyGame' and write a player script"

"Hold down the W key for 2 seconds to test walking"

"Cast a ray from the player downward to check for ground"

"Get the camera position and move it to look at the player"

"Show me the latest error messages from the running game"
