## Why TRELLO_GET_LISTS_CARDS_BY_ID_LIST is rated Low

This tool retrieves existing card data from a Trello list. It has no capability to create, modify, delete, or execute actions. The worst case misuse is unauthorized viewing of cards the user may not have access to, which is a low-severity information disclosure risk within the context of Trello board visibility.

From the tool's own definition: "Tool name contains 'GET' and description states it 'Fetches cards' with 'options to filter and customize the returned card data' — purely a retrieval operation with no modification, deletion, or execution of side effects."
