SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires unity-mcp-cli.

What problem does it solve? Locating Unity's built-in assets (default materials, shaders, sprites, fonts) inside the Editor's internal resources is not possible through normal project asset searches, forcing developers to guess names or browse documentation manually. ## Core Features & Use Cases - Built-in Asset Search: Query the Unity Editor's internal Resources/unity_builtin_extra bundle by asset name and type. - Result Limiting: Control the maximum number of returned assets with the maxResults parameter to keep output manageable. - Structured References: Receive AssetObjectRef results containing instanceID, asset type, path, and GUID for use in other Unity MCP tools. - Use Case: You need the default UI sprite or a built-in shader for a script-generated material. Run the search with a name filter to retrieve its reference and assign it programmatically. ## Quick Start Ask the AI to find the built-in Unity asset named Default-Material using the assets-find-built-in tool.

FAQPage Schema
How do I find Unity built-in assets like default materials or shaders?▼

Use the assets-find-built-in tool through unity-mcp-cli with a name filter such as Default-Material. It searches the Editor's internal Resources/unity_builtin_extra bundle and returns matching asset references with instanceID and type.

How to search Unity built-in resources by asset type?▼

Pass the type parameter along with an optional name filter in the JSON input. The tool filters built-in assets by the specified System.Type and returns a list of matching AssetObjectRef entries.

Can I look up Unity built-in assets by GUID?▼

No, GUID-based lookup is not supported because Unity built-in assets do not have GUIDs. You must search by name and type, and the returned references are identified primarily by instanceID.

Why does unity-mcp-cli command not work or return not found?▼

The CLI may not be installed globally. Install it with npm install -g unity-mcp-cli or prefix commands with npx, and consult the unity-initial-setup skill for full installation instructions.

How do I limit the number of built-in asset search results?▼

Set the maxResults integer parameter in the input JSON. When the number of matching assets exceeds this limit, the returned result list is truncated to the specified count.
