Unity-MCP connects AI coding agents to the Unity game engine through MCP, letting them work with the Unity Editor and running games. It is used by game developers to generate code, automate development and testing, debug projects, and add AI-driven behavior to games. The catalogue entries provide skills, instructions, an MCP integration, and settings for operating this workflow.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00057 | $0.00873 |
| Opus 5 | $0.00028 | $0.00436 |
| Sonnet 5 | $0.00011 | $0.00175 |
| Haiku 4.5 | $0.00006 | $0.00087 |
Grade A, and why
gameobject-component-list-all 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 8d 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.
How it starts
The opening of the file, as written. The whole thing — 132 lines — stays where its author put it; the contents beside it link to each section on GitHub.
GameObject / Component / List All
List C# class names extended from UnityEngine.Component. Use this to find component type names for 'gameobject-component-add' tool. Results are paginated to avoid overwhelming responses.
Inputs
search(optional) — case-insensitive substring filter on type names.page(default 0, 0-based) — page index.pageSize(default 5, range 1..500) — items per page.
Behavior
Enumerates AllComponentTypes (every non-abstract subclass of UnityEngine.Component), filters by search if supplied, then returns a ComponentListResult containing the requested page plus TotalCount / TotalPages so the caller can iterate.
How to Call
unity-mcp-cli run-tool gameobject-component-list-all --input '{
"search": "string_value",
"page": 0,
"pageSize": 0
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool gameobject-component-list-all --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool gameobject-component-list-all --input-file - <<'EOF' {"param": "value"} EOF
Troubleshooting
If unity-mcp-cli is not found, either install it globally (npm install -g unity-mcp-cli) or use npx unity-mcp-cli instead.
Read the /unity-initial-setup skill for detailed installation instructions.

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.

gameobject-component-list-all is a skill published in the GitHub repository IvanMurzak/Unity-MCP (4,198 stars, last pushed 3d ago), licensed Apache-2.0. It adds 57 tokens to every session and 873 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
