description: "Get detailed data about a shader asset — properties, subshaders, passes, compilation messages, and supported status. Supports token-saving path-scoped reads via `paths` or `viewQuery`. Use 'assets-find' with `t:Shader` or 'assets-shader-list-all' to locate the shader first."

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.

Toggles (most default off to keep responses small)

• `includeMessages` (default `true`) — shader compilation messages.
• `includeProperties` (default `false`) — uniforms list.
• `includeSubshaders` (default `false`) — subshader and pass structure.
• `includeSourceCode` (default `false`) — pass source code. Implies `includeSubshaders` and can produce very large responses.

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`. The result populates `View` on the returned `ShaderData`. These two parameters are mutually exclusive.

Path syntax

`fieldName`, `nested/field`, `arrayField/[i]`, `dictField/[key]`. Leading `#/` is stripped.

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",
  "paths": "string_value",
  "viewQuery": "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 | | `paths` | `any` | No | Optional. List of paths to read individually via Reflector.TryReadAt against the underlying Shader asset. Path syntax: 'fieldName', 'nested/field', 'arrayField/[i]', 'dictField/[key]'. Mutually exclusive with 'viewQuery'. | | `viewQuery` | `any` | No | Optional. View-query filter routed through Reflector.View against the underlying Shader asset. Mutually exclusive with 'paths'. |
