Features

• 17 composite mega-tools -- scene, node, script, shader, animation, tilemap, physics, audio, navigation, UI, and more
• Full scene control -- create, parse, and modify .tscn files directly without Godot running
• GDScript CRUD -- create, read, write, and attach scripts in a single call
• Tiered token optimization -- compressed descriptions + on-demand help tool

Install

Runs over stdio by default. No credentials, no account, no relay -- the server reads and writes your local Godot project files directly. Godot 4.x is optional (only run/stop/export and editor actions need the binary).

Via npx (recommended)

npx -y @n24q02m/better-godot-mcp@latest

MCP client config

Add to your client's MCP config (Claude Code, Cursor, Windsurf, Codex, mcp.json):

{
  "mcpServers": {
    "better-godot-mcp": {
      "command": "npx",
      "args": ["-y", "@n24q02m/better-godot-mcp"],
      "env": {
        "GODOT_PROJECT_PATH": "/path/to/your/godot/project"
      }
    }
  }
}

GODOT_PROJECT_PATH is optional -- every tool also accepts a project_path argument per call.

Via Docker

docker run -i --rm -v /path/to/your/godot/project:/project n24q02m/better-godot-mcp

The image is published for amd64 and arm64. Mount your project directory so the server can read and write scene, script, and resource files.

Configuration

The Godot binary is auto-detected from common install locations and PATH. No environment variables are required for basic usage. Optionally set GODOT_PROJECT_PATH and GODOT_PATH to override the defaults.

Variable	Required	Default	Description
GODOT_PROJECT_PATH	No	-	Default project path (tools also accept a project_path param)
GODOT_PATH	No	Auto-detected	Path to the Godot binary

HTTP transport

The server runs over stdio by default. To serve over Streamable HTTP instead, pass --http or set MCP_TRANSPORT=http (TRANSPORT_MODE=http is also accepted). HTTP mode exposes an unauthenticated /mcp endpoint -- there are no credentials to protect, so it is meant for trusted local or self-hosted use.

Variable	Required	Default	Description
MCP_TRANSPORT	No	stdio	Set to http for Streamable HTTP transport
PORT	No	0 (auto-assign)	HTTP port (HTTP mode only)
HOST	No	Server default	HTTP host (HTTP mode only)

Limitations

• Requires Godot 4.x project structure
• Scene files (.tscn) are parsed/modified via text manipulation, not Godot's internal API
• run/stop/export actions require Godot binary to be installed
• Docker mode has limited filesystem access (mount your project directory)

Security

• Binary detection -- Multi-path Godot detection (env, PATH, common locations)
• Project validation -- Verifies project.godot exists before operations
• Cross-platform -- Windows, macOS, Linux path handling

Build from source

git clone https://github.com/n24q02m/better-godot-mcp.git
cd better-godot-mcp
bun install
bun run dev          # stdio mode (default)
bun run dev:http     # Streamable HTTP mode

Trust model

This plugin implements TC-Local (no auth required -- no credentials stored). See the trust model reference for full classification.

Mode	Storage	Encryption	Who can read your data?
stdio (default)	N/A (no credentials)	N/A	N/A
HTTP self-host	N/A (no credentials)	N/A	N/A
