check_availability_and_list_bookings
AI agents call check_availability_and_list_bookings to retrieve information from DiSH MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

The sibling tools 'book_room' (Write) and 'cancel_booking' (Destructive) are clearly more severe. Low severity because misuse of a read operation causes no harm to system state.
From the tool's definition Tool name 'check_availability_and_list_bookings' indicates retrieval operations: 'check_availability' and 'list_bookings' are query/read operations with no modification. Server description confirms it 'search[es] availability' as a core function.
