Parameters from the server's own tool schema.
This tool performs a read-only query of Square catalog data (items, categories, taxes, etc.). It retrieves and lists existing catalog objects without creating, modifying, deleting, or executing any side effects. The term 'list' is a classic Read operation indicator. Low severity because misuse would only expose catalog metadata, not enable financial transactions, deletions, or code execution.
