version: "1.0.0" name: assets-material-create description: Create a new Material asset with default parameters at a given 'Assets/'-rooted path ending in '.mat'. Creates intermediate folders if missing. Use 'assets-shader-list-all' to find a valid shaderName. metadata: generated-by: mcp-plugin-dotnet

Assets / Create Material

Create new material asset with default parameters. Creates folders recursively if they do not exist. Provide proper 'shaderName' - use 'assets-shader-list-all' tool to find available shaders.

Inputs

assetPath — must start with Assets/ and end with .mat.
shaderName — name resolvable via UnityEngine.Shader.Find.

Behavior

Throws if the path is empty, malformed, or the shader cannot be resolved. Creates a default Material from the resolved shader, saves it, refreshes the AssetDatabase, and returns an AssetObjectRef pointing at the new asset.

How to Call

bash

unity-mcp-cli run-tool assets-material-create --input '{
  "assetPath": "string_value",
  "shaderName": "string_value"
}'

For complex input (multi-line strings, code), save the JSON to a file and use:
```bash
unity-mcp-cli run-tool assets-material-create --input-file args.json
```
Or pipe via stdin (recommended):
```bash
unity-mcp-cli run-tool assets-material-create --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
`assetPath`	`string`	Yes	Asset path. Starts with 'Assets/'. Ends with '.mat'.
`shaderName`	`string`	Yes	Name of the shader that need to be used to create the material.
