assets-material-create

name	assets-material-create
description	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.

Assets / Create Material

How to Call

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:

unity-mcp-cli run-tool assets-material-create --input-file args.json

Or pipe via stdin (recommended):

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'.
