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.

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.

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)

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.

Command	Description
better-godot-mcp	Start the MCP server (stdio default; --http for Streamable HTTP)
better-godot-mcp detect	Print the detected Godot binary as JSON (path, version, source); exits non-zero when none is found
better-godot-mcp doctor	Health-check the Godot binary and the current project (GODOT_PROJECT_PATH, else the working directory)

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

{
  "found": true,
  "path": "/path/to/godot",
  "version": {
    "major": 4,
    "minor": 6,
    "patch": 3,
    "label": "stable.official",
    "raw": "4.6.3.stable.official"
  },
  "source": "system"
}

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

[ok] godot binary: /path/to/godot (source: system)
[ok] godot version: 4.6.3.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

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
