Better Godot Mcp

ARCHIVED 2026-09-13 — This repository is no longer maintained. Use the Godot editor + GDScript CLI toolchain instead of this MCP server. Existing installations keep working but receive no updates or support.

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 for file operations; only run/stop/export and editor actions need a Godot binary. The detector accepts Godot >=4.1. Live engine compatibility is currently verified with Godot 4.7.1 stable; this does not claim that every future minor release has been verified.

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.

Smithery

better-godot-mcp ships a smithery.yaml so it can be discovered and deployed through Smithery. Smithery launches the server over stdio via npx -y @n24q02m/better-godot-mcp, and no configuration is required to start -- the server has no credentials and reads your local Godot project files directly.

Tools

Comparison

How better-godot-mcp stacks up against direct competitors in each pillar:

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.

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.

Limitations

• Requires a Godot 4.x project structure; a Godot binary is optional for file operations
• 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)

CLI

The better-godot-mcp binary runs the MCP server by default (stdio; add --http for Streamable HTTP). It also exposes two diagnostic subcommands for checking your Godot environment before wiring up an MCP client.

# Detect the Godot binary (JSON output)npx -y @n24q02m/better-godot-mcp detect

{  "found": true,  "path": "/path/to/godot",  "version": {    "major": 4,    "minor": 7,    "patch": 1,    "label": "stable.official",    "raw": "4.7.1.stable.official"  },  "source": "system"}

# Health-check the Godot binary and projectnpx -y @n24q02m/better-godot-mcp doctor

[ok] godot binary: /path/to/godot (source: system)[ok] godot version: 4.7.1.stable.official[warn] project: no project.godot found at /path/to/cwd (set GODOT_PROJECT_PATH)

detect exits 1 when no Godot binary is found; doctor exits 1 when the binary is missing (a missing project.godot is only a warning).

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
