unity-scene-management

unity-scene-management is a skill for Claude Code, Codex from akiojin/unity-mcp-server. It costs 0 tokens per session (3,654 once invoked), scanned A, original, MIT.

Tools and procedures for creating, editing, loading, and inspecting Unity scenes and GameObjects. Unity is a game development environment, and a GameObject is an object in a Unity scene, such as a player, camera, or light.

In plain words
What is it for?
Use them to create scenes and objects, add components, set properties, inspect hierarchies, and manage scene loading.
Why use it?
They make scene changes and hierarchy checks repeatable instead of requiring manual editor work for every operation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

unity-scene-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Unity Scene & GameObject Management

A guide for creating, managing, and analyzing Unity scenes, GameObjects, and components.

Quick Start

1. Check Current Scene State

// List loaded scenes
mcp__unity-mcp-server__list_scenes({ includeLoadedOnly: true })

// Current scene info
mcp__unity-mcp-server__get_scene_info({ includeGameObjects: true })

// Get hierarchy (lightweight)
mcp__unity-mcp-server__get_hierarchy({
  nameOnly: true,
  maxObjects: 100
})

2. Create GameObject

// Empty GameObject
mcp__unity-mcp-server__create_gameobject({
  name: "GameManager"
})

// Primitive
mcp__unity-mcp-server__create_gameobject({
  name: "Floor",
  primitiveType: "plane",
  position: { x: 0, y: 0, z: 0 },
  scale: { x: 10, y: 1, z: 10 }
})

3. Add Component

// Add Rigidbody
mcp__unity-mcp-server__add_component({
  gameObjectPath: "/Player",
  componentType: "Rigidbody",
  properties: { mass: 1.5, useGravity: true }
})

Scene Operations

Create Scene

// Create and load new scene
mcp__unity-mcp-server__create_scene({
  sceneName: "Level01",
  path: "Assets/Scenes/",
  loadScene: true,
  addToBuildSettings: true
})

Load Scene

// Single scene load (replaces current scene)
mcp__unity-mcp-server__load_scene({
  scenePath: "Assets/Scenes/MainMenu.unity",
  loadMode: "Single"
})

// Additive load (adds to current scene)
mcp__unity-mcp-server__load_scene({
  scenePath: "Assets/Scenes/UI.unity",
  loadMode: "Additive"
})

Save Scene

// Save current scene
mcp__unity-mcp-server__save_scene()

// Save as new file
mcp__unity-mcp-server__save_scene({
  scenePath: "Assets/Scenes/Level01_backup.unity",
  saveAs: true
})

List & Info

// All scenes in project
mcp__unity-mcp-server__list_scenes()

// Only scenes in build settings
mcp__unity-mcp-server__list_scenes({ includeBuildScenesOnly: true })

// Specific scene details
mcp__unity-mcp-server__get_scene_info({
  scenePath: "Assets/Scenes/Main.unity",
  includeGameObjects: true
})

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
