How do I install Godot Forge?

Copy the stdio config for Cursor, Claude Desktop, Claude Code, or VS Code on this page. It uses the publisher's install, not a PlugMCP proxy.

Does Godot Forge need an API key?

The publisher lists these environment variables: GODOT_PATH.

What transport does Godot Forge use?

Godot Forge runs locally over stdio.

When was Godot Forge last checked?

Last checked 2026-11-09. Godot 4 MCP server — test runner, API docs, script analysis, scene parsing, LSP.

FAQ

Questions

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.

Add to your IDE

claude mcp add godot-forge -- npx -y godot-forge

Add to .cursor/mcp.json:

{
  "mcpServers": {
    "godot-forge": {
      "command": "npx",
      "args": ["-y", "godot-forge"]
    }
  }
}

Add to .vscode/mcp.json:

{
  "servers": {
    "godot-forge": {
      "command": "npx",
      "args": ["-y", "godot-forge"]
    }
  }
}

Add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "godot-forge": {
      "command": "npx",
      "args": ["-y", "godot-forge"]
    }
  }
}

Add to settings.json:

{
  "context_servers": {
    "godot-forge": {
      "command": {
        "path": "npx",
        "args": ["-y", "godot-forge"]
      }
    }
  }
}

Add to ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%/Claude/claude_desktop_config.json (Windows):

{
  "mcpServers": {
    "godot-forge": {
      "command": "npx",
      "args": ["-y", "godot-forge"]
    }
  }
}

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.
