개요
Open-source Godot MCP server that lets AI assistants (Claude Code, Cursor, Codex, and more) control the Godot 4 editor directly through the Model Context Protocol (MCP). - — node add/remove/edit and property changes go through the editor undo stack - — strings like Vector2(100, 200), #ff0000, Color(1,0,0) are converted automatically - — exponential backoff on the plugin side (1s → 60s) - — bidirectional ping/pong to keep the WebSocket alive - — standard protocol between the Godot plugin and the Node.

Godot MCP
Language: English | 简体中文
Open-source Godot MCP server that lets AI assistants (Claude Code, Cursor, Codex, and more) control the Godot 4 editor directly through the Model Context Protocol (MCP).
AI client ←—stdio/MCP—→ Node.js server ←—WebSocket:6505—→ Godot editor plugin
Overview
| Component | Role |
|---|---|
| Godot plugin | WebSocket client that receives JSON-RPC requests and executes commands via editor APIs |
| Node.js MCP server | Speaks stdio to AI clients; runs a WebSocket server (default port 6505) to forward tool calls |
| Command router | command_router.gd aggregates 24 command modules with 173 handlers |
| Runtime services | 3 autoloads (MCPRuntimeBridge / MCPInputBridge / MCPScreenshotBridge) use user:// IPC for in-game inspection, input simulation, and screenshots |
Core features
- UndoRedo integration — node add/remove/edit and property changes go through the editor undo stack
- Smart type parsing — strings like
Vector2(100, 200),#ff0000,Color(1,0,0)are converted automatically - Reconnect with backoff — exponential backoff on the plugin side (1s → 60s)
- Heartbeat — bidirectional ping/pong to keep the WebSocket alive
- JSON-RPC 2.0 — standard protocol between the Godot plugin and the Node.js server
