Find a seat by seat number in an office
AI agents call find_seat_by_number to retrieve information from MCP Seat Reservation Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

No data is created, modified, deleted, or executed. The blast radius of misuse is minimal — worst case, an agent could enumerate seat numbers to understand office layout, which is low sensitivity information in a reservation system.
