Why get_subscription is rated Low
This tool retrieves subscription data for read-only purposes. While it may expose financial context (subscription tiers, billing cycles), it does not move money, execute commands, or modify data. The primary action is fetching/querying existing subscription information, which is characteristic of a Read operation. Even in a CRM handling financial records, retrieval alone is not a Financial category action.
From the tool's definition Tool name 'get_subscription' and description 'Fetch a single subscription' indicate a retrieval operation with no side effects. The description specifies it retrieves information ('customer, tier, billing cycle, and renewal info') without modification.

get_subscription is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
