Assets / Find (Built-in)

How to Call

unity-mcp-cli run-tool assets-find-built-in --input '{
  "name": "string_value",
  "type": "string_value",
  "maxResults": 0
}'

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
