Why list_inventory_categories is rated Low

It is a pure query operation that returns information based on optional parameters (parent category, query string). The highest impact would be information disclosure if categories contain sensitive data, but that is a Read-category risk.
From the tool's definition Tool description states 'List inventory categories' with filtering and sorting capabilities. The verb 'list' combined with 'omit parentCategory to search' and 'query filters' indicates data retrieval with no modification.
