Quick Start (3 Minutes)

Requirements

• Godot 4.x
• Node.js 18+
• MCP-compatible client (Claude Desktop, Cursor, Cline, OpenCode, etc.)

1) Run GoPeak

npx -y gopeak

or install globally:

npm install -g gopeak
gopeak

2) Add MCP client config

{
  "mcpServers": {
    "godot": {
      "command": "npx",
      "args": ["-y", "gopeak"],
      "env": {
        "GODOT_PATH": "/path/to/godot",
        "GOPEAK_TOOL_PROFILE": "compact"
      }
    }
  }
}

GOPEAK_TOOL_PROFILE=compact is the default. It exposes 33 core tools with 22 dynamic tool groups (78 additional tools) that activate on demand — keeping token usage low while preserving full capability.

3) First prompts to try

• "List Godot projects in /your/projects and show project info."
• "Create scenes/Player.tscn with CharacterBody2D root and add a movement script."
• "Run project, get debug output, then fix top error."

---

Why GoPeak

• Real project feedback loop: run the game, inspect logs, and fix in-context.
• 110+ tools available across scene/script/resource/runtime/LSP/DAP/input/assets.
• Token-efficient by default: compact tool surface (33 tools) + dynamic tool groups. Only activate what you need — no more 110-tool context bombs.
• Dynamic tool groups: search with tool.catalog and matching groups auto-activate. Or manually activate with tool.groups.
• Deep Godot integration: ClassDB queries, runtime inspection, debugger hooks, bridge-based scene/resource edits.

Best For

• Solo/indie developers moving quickly with AI assistance
• Teams that need AI grounded in actual project/runtime state
• Debug-heavy workflows (breakpoints, stack traces, live runtime checks)

---

Tool Surface Model (Important)

GoPeak supports three exposure profiles:

• compact (default): 33 core tools + 22 dynamic tool groups (78 additional tools activated on demand)
• full: exposes full legacy tool list (110+)
• legacy: same exposed behavior as full

Configure with either:

• GOPEAK_TOOL_PROFILE
• MCP_TOOL_PROFILE (fallback alias)

Dynamic Tool Groups (compact mode)

In compact mode, 78 additional tools are organized into 22 groups that activate automatically when needed:

Group	Tools	Description
scene_advanced	3	Duplicate, reparent nodes, load sprites
uid	2	UID management for resources
import_export	5	Import pipeline, reimport, validate project
autoload	4	Autoload singletons, main scene
signal	2	Disconnect signals, list connections
runtime	4	Live scene inspection, runtime properties, metrics
resource	4	Create/modify materials, shaders, resources
animation	5	Animations, tracks, animation tree, state machine
plugin	3	Enable/disable/list editor plugins
input	1	Input action mapping
tilemap	2	TileSet and TileMap cell painting
audio	4	Audio buses, effects, volume
navigation	2	Navigation regions and agents
theme_ui	3	Theme colors, font sizes, shaders
asset_store	3	Search/download CC0 assets
testing	6	Screenshots, viewport capture, input injection
dx_tools	4	Error log, project health, find usages, scaffold
intent_tracking	9	Intent capture, decision logs, handoff briefs
class_advanced	1	Class inheritance inspection
lsp	3	GDScript completions, hover, symbols
dap	6	Breakpoints, stepping, stack traces
version_gate	2	Version validation, patch verification

How it works:

1. Auto-activation via catalog: Search with tool.catalog and matching groups activate automatically.

   "Use tool.catalog with query animation and show relevant tools."

2. Manual activation: Directly activate a group with tool.groups.

   "Use tool.groups to activate the dap group for debugging."

3. Deactivation: Remove groups when done to reduce context.

   "Use tool.groups to reset all active groups."

The server sends notifications/tools/list_changed so MCP clients (Claude Code, Claude Desktop) automatically refresh the tool list.

Don't worry about tokens

GoPeak uses cursor-based pagination for tools/list — even in full profile, tools are delivered in pages (default 33) instead of dumping all 110+ definitions at once. Your AI client fetches the next page only when it needs more.

Set page size with GOPEAK_TOOLS_PAGE_SIZE:

{
  "env": {
    "GOPEAK_TOOLS_PAGE_SIZE": "25"
  }
}

Installation Options

A) Recommended: npx

npx -y gopeak

B) Global install

npm install -g gopeak
gopeak

C) From source

git clone https://github.com/HaD0Yun/Gopeak-godot-mcp.git
cd godot-mcp
npm install
npm run build
node build/index.js

GoPeak also exposes two CLI bin names:

• gopeak
• godot-mcp

• Platform Roadmap
• Unity-MCP Benchmark Plan
• Release Process

CI

GitHub Actions runs on push/PR and executes:

1. npm run build
2. npx tsc --noEmit
3. npm run smoke

Run the same checks locally:

npm run ci

---

Versioning & Release

Use the built-in bump script to keep package.json and server.json in sync:

node scripts/bump-version.mjs patch
node scripts/bump-version.mjs minor --dry-run

Full release checklist: docs/release-process.md.

---

Addons (Recommended)

Auto Reload + Editor Bridge + Runtime Addon installer

Install in your Godot project folder:

curl -sL https://raw.githubusercontent.com/HaD0Yun/Gopeak-godot-mcp/main/install-addon.sh | bash

PowerShell:

iwr https://raw.githubusercontent.com/HaD0Yun/Gopeak-godot-mcp/main/install-addon.ps1 -UseBasicParsing | iex

Then enable plugins in Project Settings → Plugins (especially godot_mcp_editor for bridge-backed scene/resource tools).

---

Project Visualizer

Visualize your entire project architecture with visualizer.map (map_project legacy). Scripts are grouped by folder structure into color-coded categories.

Quick Prompt Examples

Build

• "Create a Player scene with CharacterBody2D, Sprite2D, CollisionShape2D, and a basic movement script."
• "Add an enemy spawner scene and wire spawn signals to GameManager."

Debug

• "Run the project, collect errors, and fix the top 3 issues automatically."
• "Set a breakpoint at scripts/player.gd:42, continue execution, and show stack trace when hit."

Runtime testing

• "Press ui_accept, move mouse to (400, 300), click, then capture a screenshot."
• "Inspect live scene tree and report nodes with missing scripts or invalid references."

Discovery & dynamic groups

• "Use tool.catalog with query tilemap and list the most relevant tools."
• "Activate the dap tool group for breakpoint debugging with tool.groups."
• "Find import pipeline tools with tool.catalog query import and run the best one for texture settings."
• "Reset all active tool groups with tool.groups to reduce context."

Troubleshooting

• Godot not found → set GODOT_PATH
• No MCP tools visible → restart your MCP client
• Project path invalid → confirm project.godot exists
• Runtime tools not working → install/enable runtime addon plugin
• Need a tool that is not visible → run tool.catalog to search and auto-activate matching groups, or use tool.groups to activate a specific group
