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.

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 | $0.00050 | $0.01830 |
| Opus 5 | $0.00025 | $0.00915 |
| Sonnet 5 | $0.00010 | $0.00366 |
| Haiku 4.5 | $0.00005 | $0.00183 |
Grade A, and why
assets-get-data 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.
How it starts
The opening of the file, as written. The whole thing — 195 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Assets / Get Data
Get asset data from the asset file in the Unity project. It includes all serializable fields and properties of the asset. Use 'assets-find' tool to find asset before using this tool.
Path-scoped reads (token-saving)
Supply paths (a list of paths) to read only the listed fields/elements via Reflector.TryReadAt, or viewQuery (a ViewQuery) to navigate to a subtree and/or filter by name regex / max depth / type via Reflector.View. These two parameters are mutually exclusive — supply at most one. When neither is supplied the full asset is serialized (backwards compatible).
Path syntax
fieldName, nested/field, arrayField/[i], dictField/[key]. Leading #/ is stripped.
How to Call
unity-mcp-cli run-tool assets-get-data --input '{
"assetRef": "string_value",
"paths": "string_value",
"viewQuery": "string_value"
}'
For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool assets-get-data --input-file args.jsonOr pipe via stdin (recommended):
unity-mcp-cli run-tool assets-get-data --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.
Input
| Name | Type | Required | Description |
|---|---|---|---|
assetRef |
any |
Yes | Reference to UnityEngine.Object asset instance. It could be Material, ScriptableObject, Prefab, and any other Asset. Anything located in the Assets and Packages folders. |
paths |
any |
No | Optional. List of paths to read individually via Reflector.TryReadAt. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'. |
viewQuery |
any |
No | Optional. View-query filter routed through Reflector.View — combines a starting Path, a case-insensitive NamePattern regex, MaxDepth, and an optional TypeFilter. Mutually exclusive with 'paths'. |
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.

assets-get-data is a skill published in the GitHub repository IvanMurzak/Unity-MCP (4,079 stars, last pushed 10d ago), licensed Apache-2.0. It adds 50 tokens to every session and 1,830 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.
