AI agents call booking_get_reservations to retrieve information from MCP Booking without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves reservation information from the user's Booking.com account without creating, modifying, or deleting anything. It is a pure query operation. Severity is medium rather than low because reservations contain personally identifiable information (dates, property details, guest names) and financial details (pricing), so unauthorized access could enable identity fraud or financial exploitation.
From the tool's definition Tool name 'booking_get_reservations' and description 'Get all current and upcoming reservations' indicate retrieval of existing reservation data with no modification or deletion. The 'Get' verb and 'get' action are characteristic of Read operations.
