Unity-MCP 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.

How to Call

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:

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

Or pipe via stdin (recommended):

unity-mcp-cli run-tool assets-shader-get-data --input-file - <<'EOF'
{"param": "value"}
EOF

Troubleshooting

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
