Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "godot-forge": {
      "command": "npx",
      "args": [
        "-y",
        "godot-forge"
      ],
      "env": {
        "GODOT_PATH": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add godot-forge --env GODOT_PATH=your-value -- npx -y godot-forge

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Common questions

Is Godot Forge safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

README from the maker

Open the README

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

Godot Forge The MCP server for Godot 4. Test runner, API docs, script analysis, and more.

AI coding assistants are structurally bad at GDScript. Models trained on data skewed towards Godot 3 hallucinate deprecated APIs (yield instead of await, KinematicBody instead of CharacterBody3D, export var instead of @export var). Godot Forge fixes this.

8 tools. Zero config. Works with every MCP-compatible IDE.

Install

npx -y godot-forge

That's it. Godot Forge auto-detects your Godot binary (Steam, Homebrew, direct download) and finds your project.godot automatically.

Tools

Tool	Description	Needs Godot	Needs Editor
`godot_run_tests`	Run GUT/GdUnit4 tests, get structured pass/fail results	Yes	No
`godot_search_docs`	Search Godot 4 API docs with 3→4 migration mapping	No	No
`godot_analyze_script`	Detect 10 GDScript pitfalls (deprecated API, coupling, re-entrancy)	No	No
`godot_analyze_scene`	Parse .tscn/.tres, detect antipatterns and format errors	No	No
`godot_get_project_info`	Project structure overview with progressive disclosure	No	No
`godot_get_diagnostics`	LSP diagnostics from Godot's language server	No	Yes
`godot_run_project`	Launch/stop project, capture debug output	Yes	No
`godot_screenshot`	Capture viewport screenshot as base64 PNG	Yes	No

[!TIP]

6 of 8 tools work without Godot installed. Only test running, project launching, and screenshots need the binary.

Features

Test Runner

Auto-detects GUT and GdUnit4. Returns structured JSON with pass/fail counts, failure details with file paths and line numbers. Supports filtering by script, method, or inner class.

Ask your AI: "Run the water profile tests"

→ { total: 5, passed: 5, failed: 0, duration_ms: 462 }

Godot 3→4 Migration Mapping

The #1 reason AI writes broken GDScript. When your AI queries a deprecated API, it gets the correct Godot 4 equivalent instantly (30+ mappings covering classes, methods, syntax, and constants).

Query: "KinematicBody"  →  "Renamed to CharacterBody3D in Godot 4"

Query: "yield" → "yield(obj, 'signal') → await obj.signal" Query: "instance()" → "instance() → instantiate()"

Script Analysis: 10 Pitfalls

Every pitfall detected from real game development:

#	Pitfall	What It Catches
1	Godot 3→4 API	`yield`, `connect("signal")`, `export var`, `instance()`
2	Giant scripts	Over 300 lines. Should be split
3	`:=` on Variant	Type inference on `Dictionary.get()` causes parse errors
4	Tight coupling	Excessive `get_node("../../...")` references
5	Signal re-entrancy	Signal emitted between state changes
6	Autoload misuse	Too many autoloads, `static func` on autoloads
7	Missing disconnect	`connect()` without `_exit_tree()` cleanup
8	`_init()` timing	Node tree access before node is in tree
9	Python-isms	List comprehensions, `len()`, Python imports
10	.tres type field	Custom class name instead of `type="Resource"`

Scene Analysis

Parses .tscn and .tres files. Detects deep nesting (>8 levels), oversized scenes (>100 nodes), missing script references, preload() in .tres, integer resource IDs, and more.

LSP Diagnostics

Connects to Godot's built-in language server (runs automatically when the editor is open). Returns real compiler errors and warnings (no guesswork).

[!NOTE]

Requires the Godot editor to be running with your project open. All other tools work without the editor.

Screenshot Capture

Captures the game viewport as a PNG image. Loads the project's main scene (or a specified scene), waits for rendering, and returns the screenshot as base64 for the AI to see.

Configuration

Godot Binary

Auto-detected in this order:

GODOT_PATH environment variable
godot / godot4 in PATH
Steam installation (macOS, Windows, Linux)
Platform defaults (/Applications/Godot.app, Homebrew, Scoop, Flatpak, Snap, etc.)

Override manually:

export GODOT_PATH="/path/to/godot"

See Godot Detection for the full list of searched paths.

Project Directory

Auto-detected by walking up from the current directory to find project.godot. Override:

npx godot-forge --project /path/to/godot/project

Requirements

Node.js 18+: for npx execution
Godot 4.x: auto-detected (optional for 6 of 8 tools)
Any MCP-compatible IDE: Claude Code, Cursor, VS Code, Windsurf, Zed, and more

Design Principles

Outcomes, not operations: Each tool delivers a complete result, not raw API wrapping
8 curated tools: No 93-tool context bloat (why this matters)
Progressive disclosure: Summaries first, details on demand
`spawn()` not `exec()`: No command injection, no Windows quoting bugs
Actionable errors: Every error includes a suggestion the AI can act on
Cross-platform: macOS, Windows, Linux. Steam and non-Steam installs.
