For complex input (multi-line strings, code), save the JSON to a file and use:
unity-mcp-cli run-tool assets-find-built-in --input-file args.json
Or pipe via stdin (recommended):
unity-mcp-cli run-tool assets-find-built-in --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
`name`	`string`	No	The name of the asset to filter by.
`type`	`any`	No	The type of the asset to filter by.
`maxResults`	`integer`	No	Maximum number of assets to return. If the number of found assets exceeds this limit, the result will be truncated.
