Agent skill

assets-shader-get-data

Get detailed data about a shader asset in the Unity project. Returns shader properties, subshaders, passes, compilation errors, and supported status. Use 'assets-find' tool with filter 't:Shader' to find shaders, or 'assets-shader-list-all' tool to list all shader names.

Assets / Shader / Get Data

How to Call

bash
unity-mcp-cli run-tool assets-shader-get-data --input '{
  "assetRef": "string_value",
  "includeMessages": "string_value",
  "includeProperties": "string_value",
  "includeSubshaders": "string_value",
  "includeSourceCode": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:

bash
unity-mcp-cli run-tool assets-shader-get-data --input-file args.json

Or pipe via stdin (recommended):

bash
unity-mcp-cli run-tool assets-shader-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.
includeMessages any No Include compilation error and warning messages. Default: true
includeProperties any No Include shader properties (uniforms) list. Default: false
includeSubshaders any No Include subshader and pass structure. Default: false
includeSourceCode any No Include pass source code in subshader data. Requires 'includeSubshaders' to be true. Can produce very large responses. Default: false
