unity-mcp-orchestrator

unity-mcp-orchestrator is a skill for Claude Code, Codex from isaacsight/kernel. It costs 72 tokens per session (3,464 once invoked), scanned A, a copy of unity-mcp-orchestrator, MIT.

A guide for controlling the Unity Editor through MCP, a standard way for AI tools to work with other software. It covers changing game objects, scripts, scenes, tests, and editor resources.

In plain words
What is it for?
Use it when creating or editing Unity game objects, writing or changing scripts, managing scenes, running tests, checking console errors, or taking editor screenshots.
Why use it?
It reduces guesswork when automating Unity projects and helps keep actions aligned with the current editor and scene. It also highlights checking results for version- or project-specific differences.

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-mcp-orchestrator 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 3d 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-MCP Operator Guide

This skill helps you effectively use the Unity Editor with MCP tools and resources.

Template Notice

Examples in references/workflows.md and references/tools-reference.md are reusable templates. They may be inaccurate across Unity versions, package setups (UGUI/TMP/Input System), and project-specific conventions. Please check console, compilation errors, or use screenshot after implementation.

Before applying a template:

  • Validate targets/components first via resources and find_gameobjects.
  • Treat names, enum values, and property payloads as placeholders to adapt.

Quick Start: Resource-First Workflow

Always read relevant resources before using tools. This prevents errors and provides the necessary context.

1. Check editor state     → mcpforunity://editor/state
2. Understand the scene   → mcpforunity://scene/gameobject-api
3. Find what you need     → find_gameobjects or resources
4. Take action            → tools (manage_gameobject, create_script, script_apply_edits, apply_text_edits, validate_script, delete_script, get_sha, etc.)
5. Verify results         → read_console, manage_camera(action="screenshot"), resources

Critical Best Practices

1. After Writing/Editing Scripts: Wait for Compilation and Check Console

# After create_script or script_apply_edits:
# Both tools already trigger AssetDatabase.ImportAsset + RequestScriptCompilation automatically.
# No need to call refresh_unity — just wait for compilation to finish, then check console.

# 1. Poll editor state until compilation completes
# Read mcpforunity://editor/state → wait until is_compiling == false

# 2. Check for compilation errors
read_console(types=["error"], count=10, include_stacktrace=True)

Why: Unity must compile scripts before they're usable. create_script and script_apply_edits already trigger import and compilation automatically — calling refresh_unity afterward is redundant.

2. Use batch_execute for Multiple Operations

Changes

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.
