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 | $0.00068 | $0.00570 |
| Opus 5.5 | $0.00027 | $0.00228 |
| Sonnet 5.5 | $0.00014 | $0.00114 |
| Haiku 4.5 | $0.00007 | $0.00057 |
Grade A, and why
package-remove 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 2d 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 — 72 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Package Manager / Remove
Remove (uninstall) a package from the Unity project. This removes the package from the project's manifest.json and triggers package resolution. Note: Built-in packages and packages that are dependencies of other installed packages cannot be removed. Note: Package removal may trigger a domain reload. The result will be sent after the reload completes. Use 'package-list' tool to list installed packages first.
Inputs
packageId— package name (e.g.com.unity.textmeshpro). A trailing@<version>is stripped automatically before being passed toClient.Remove, so accidental versioned IDs still work.
Behavior
First verifies the package is installed via an offline Client.List — returns a clear PackageNotFound error if not. On removal failure, surfaces Unity's error message. On success, schedules a post-domain-reload notification so the response is delivered after Unity finishes the resolution.
How to Call
unity-mcp-cli run-tool package-remove --input '{
"packageId": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool package-remove --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool package-remove --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.

package-remove is a skill published in the GitHub repository IvanMurzak/Unity-MCP (4,491 stars, last pushed today), licensed Apache-2.0. It adds 68 tokens to every session and 570 once invoked, about $0.0003 per session on Opus 5.5. 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.
