A Model Context Protocol (MCP) server for interacting with the Godot game engine.

Godot MCP enables AI assistants to launch the Godot editor, run projects, capture debug output, and control project execution - all through a standardized interface.

This direct feedback loop helps AI assistants like Claude understand what works and what doesn't in real Godot projects, leading to better code generation and debugging assistance.

• Launch Godot Editor: Open the Godot editor for a specific project
• Run Godot Projects: Execute Godot projects in debug mode
• Capture Debug Output: Retrieve console output and error messages
• Control Execution: Start and stop Godot projects programmatically
• Get Godot Version: Retrieve the installed Godot version
• List Godot Projects: Find Godot projects in a specified directory
• Project Analysis: Get detailed information about project structure
• Scene Management:
  • Create new scenes with specified root node types
  • Add nodes to existing scenes with customizable properties
  • Load sprites and textures into Sprite2D nodes
  • Export 3D scenes as MeshLibrary resources for GridMap
  • Save scenes with options for creating variants
• Input Simulation:
  • Send mouse clicks, drags, and movement to running games
  • Simulate keyboard input and key combinations
  • Trigger input actions defined in project settings
  • Type text character by character
  • Take screenshots of the running game
• UID Management (for Godot 4.4+):
  • Get UID for specific files
  • Update UID references by resaving resources

• Godot Engine installed on your system
• Node.js and npm
• An AI assistant that supports MCP (Cline, Cursor, etc.)

First, clone the repository and build the MCP server:

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

Add to your Cline MCP settings file (~/Library/Application Support/Code/User/globalStorage/saoudrizwan.claude-dev/settings/cline_mcp_settings.json):

{
  "mcpServers": {
    "godot": {
      "command": "node",
      "args": ["/absolute/path/to/godot-mcp/build/index.js"],
      "env": {
        "DEBUG": "true"                  // Optional: Enable detailed logging
      },
      "disabled": false,
      "autoApprove": [
        "launch_editor",
        "run_project",
        "get_debug_output",
        "stop_project",
        "get_godot_version",
        "list_projects",
        "get_project_info",
        "create_scene",
        "add_node",
        "load_sprite",
        "export_mesh_library",
        "save_scene",
        "get_uid",
        "update_project_uids",
        "simulate_input",
        "setup_input_simulation"
      ]
    }
  }
}

Using the Cursor UI:

1. Go to Cursor Settings > Features > MCP
2. Click on the + Add New MCP Server button
3. Fill out the form:
   • Name: godot (or any name you prefer)
   • Type: command
   • Command: node /absolute/path/to/godot-mcp/build/index.js
4. Click "Add"
5. You may need to press the refresh button in the top right corner of the MCP server card to populate the tool list

Using Project-Specific Configuration:

Create a file at .cursor/mcp.json in your project directory with the following content:

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

You can customize the server behavior with these environment variables:

• GODOT_PATH: Path to the Godot executable (overrides automatic detection)
• DEBUG: Set to "true" to enable detailed server-side debug logging

Once configured, your AI assistant will automatically run the MCP server when needed. You can use prompts like:

"Launch the Godot editor for my project at /path/to/project"

"Run my Godot project and show me any errors"

"Get information about my Godot project structure"

"Analyze my Godot project structure and suggest improvements"

"Help me debug this error in my Godot project: [paste error]"

"Write a GDScript for a character controller with double jump and wall sliding"

"Create a new scene with a Player node in my Godot project"

"Add a Sprite2D node to my player scene and load the character texture"

"Export my 3D models as a MeshLibrary for use with GridMap"

"Create a UI scene with buttons and labels for my game's main menu"

"Get the UID for a specific script file in my Godot 4.4 project"

"Update UID references in my Godot project after upgrading to 4.4"

The Godot MCP server uses a bundled GDScript approach for complex operations:

1. Direct Commands: Simple operations like launching the editor or getting project info use Godot's built-in CLI commands directly.
2. Bundled Operations Script: Complex operations like creating scenes or adding nodes use a single, comprehensive GDScript file (godot_operations.gd) that handles all operations.

This architecture provides several benefits:

• No Temporary Files: Eliminates the need for temporary script files, keeping your system clean
• Simplified Codebase: Centralizes all Godot operations in one (somewhat) organized file
• Better Maintainability: Makes it easier to add new operations or modify existing ones
• Improved Error Handling: Provides consistent error reporting across all operations
• Reduced Overhead: Minimizes file I/O operations for better performance

The bundled script accepts operation type and parameters as JSON, allowing for flexible and dynamic operation execution without generating temporary files for each operation.

Input simulation allows AI assistants to interact with your running Godot game by sending mouse clicks, keyboard input, and action triggers. This requires a small autoload script in your project.

1. Install the addon to your Godot project:

   Use the setup_input_simulation tool with your project path
   

   This copies the GodotMCPInput addon to your project's addons/ folder.

2. Enable the autoload in Godot Editor:

   • Go to Project > Project Settings > Autoload
   • Click the folder icon and select: res://addons/godot_mcp_input/godot_mcp_input.gd
   • Set Node Name to: GodotMCPInput
   • Click Add

3. Run your game - you should see in the console:

   GodotMCPInput: Listening on 127.0.0.1:7070
   

The addon runs a TCP server inside your game on port 7070. When you use simulate_input, the MCP server connects to this port and sends input commands. The game executes them and returns results.

• Game must be running: The simulate_input tool only works when your game is running with the autoload enabled. Use run_project first.
• Port 7070: The addon listens on 127.0.0.1:7070. If this port is in use, you'll need to modify the PORT constant in the addon script.
• Coordinates are viewport-relative: Mouse positions are in viewport pixels, not screen pixels. (0,0) is top-left of the game window.
• Actions must exist: When using action or action_pulse, the action name must be defined in your project's Input Map.
• Runs even when paused: The addon uses PROCESS_MODE_ALWAYS so it can receive commands even when the game tree is paused.

• Godot Not Found: Set the GODOT_PATH environment variable to your Godot executable
• Connection Issues: Ensure the server is running and restart your AI assistant
• Invalid Project Path: Ensure the path points to a directory containing a project.godot file
• Build Issues: Make sure all dependencies are installed by running npm install
• For Cursor Specifically:
• Ensure the MCP server shows up and is enabled in Cursor settings (Settings > MCP)
• MCP tools can only be run using the Agent chat profile (Cursor Pro or Business subscription)
• Use "Yolo Mode" to automatically run MCP tool requests
