Godot游戏开发MCP服务

Godot MCP Pro

Premium MCP (Model Context Protocol) server for AI-powered Godot game development. Connects AI assistants like Claude directly to your Godot editor with 187 powerful tools.

Architecture

AI Assistant ←—stdio/MCP—→ Node.js Server ←—WebSocket:6505—→ Godot Editor Plugin

• Real-time: WebSocket connection means instant feedback, no file polling
• Editor Integration: Full access to Godot's editor API, UndoRedo system, and scene tree
• JSON-RPC 2.0: Standard protocol with proper error codes and suggestions

What's in this repo

⚠️ This public repo only contains the free Godot addon/plugin. The MCP server (Node.js, required to connect AI assistants) is distributed as part of the paid package — one-time purchase, lifetime updates:

• Buy Me a Coffee: https://buymeacoffee.com/y1uda/extras
• itch.io: https://y1uda.itch.io/godot-mcp-pro

The paid zip includes the addon, the server/ directory with pre-built JavaScript, INSTALL.md, and AI-client instructions. If you cloned this repo and don't see a server/ folder, that's expected — grab the full package from one of the links above.

Quick Start

1. Install the Godot Plugin

Copy the addons/godot_mcp/ folder into your Godot project's addons/ directory.

Enable the plugin: Project → Project Settings → Plugins → Godot MCP Pro → Enable

2. Install the MCP Server

The server/ directory is only included in the full paid package (see above). After downloading and extracting the zip, run:

cd server
npm install
npm run build

3. Configure Claude Code

Add to your .mcp.json:

{
  "mcpServers": {
    "godot-mcp-pro": {
      "command": "node",
      "args": ["/path/to/server/build/index.js"],
      "env": {
        "GODOT_MCP_PORT": "6505"
      }
    }
  }
}

4. Choose Your Mode

Godot MCP Pro offers four modes to fit any client's tool limit:

--3d includes the core tools plus physics, AnimationTree and navigation, but omits uid_to_project_path, project_path_to_uid, compare_screenshots, clear_output, close_script, reload_open_scripts, set_anchor_preset and click_button_by_text to stay within the 100-tool cap.

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

Replace --lite with --minimal for the smallest footprint.

• Lite includes: project, scene, node, script, editor, input, runtime, and input_map tools.
• Minimal includes: 35 essential tools — project info, scene management, node CRUD, script editing, editor errors, input simulation, and runtime inspection.

5. CLI Mode (Alternative to MCP)

For clients without MCP support, or when you want zero context overhead, use the CLI directly from a terminal/bash tool. The CLI requires the server to be built first (Step 2).

# Top-level help — shows all command groups
node /path/to/server/build/cli.js --help

# Group help — shows commands in a group
node /path/to/server/build/cli.js node --help

# Command help — shows options for a command
node /path/to/server/build/cli.js node add --help

# Execute
node /path/to/server/build/cli.js project info
node /path/to/server/build/cli.js scene play
node /path/to/server/build/cli.js node add --type CharacterBody3D --name Player

Replace /path/to/ with the actual path where you extracted the files.

The CLI connects directly to the Godot editor plugin via WebSocket. It requires:

• Godot editor running with the MCP plugin enabled
• Server built (node build/setup.js install)
• An available port in the 6510-6514 range

Advantage: LLMs discover capabilities progressively via --help instead of loading all tool definitions upfront. This works with any LLM client that has terminal access, regardless of tool count limits.

6. Client Compatibility

7. Use It

Open your Godot project with the plugin enabled, then use Claude Code to interact with the editor.
