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

Variable	Description
GODOT_PATH	Path to the Godot executable (overrides auto-detection)
DEBUG	Set to "true" for detailed server-side logging

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

Path	Description
src/index.ts	MCP server, tool definitions, and all handlers
src/utils.ts	Pure utility functions (parameter mapping, validation, error helpers)
src/scripts/godot_operations.gd	Headless GDScript operations runner
src/scripts/mcp_interaction_server.gd	TCP interaction server autoload
tests/	Vitest test suite

Testing

The project uses Vitest with 390 tests across 3 files:

File	Tests	What it covers
tests/utils.test.ts	31	Parameter mappings, normalization, path validation, error responses, version detection
tests/tool-definitions.test.ts	157	All 149 tools defined, schemas valid, names unique, descriptions < 80 chars
tests/handlers.test.ts	202	Game command arg transforms, required-param validation, headless op path checks, source structure

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