The read-only nature and lack of side effects place it in the Read category. Severity is low because exposing historical trade data, while sensitive for privacy, does not create direct financial risk or enable destructive actions by an AI agent.
From the tool's definition Tool name contains 'get_' prefix and description states 'Get user trade history' and 'Returns all trades executed by the user.' The description explicitly notes 'No authentication required,' confirming read-only access to historical data with no side effects.
