View your upcoming reservations.
AI agents call list_reservations to retrieve information from Restaurant Reservation MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and displays existing reservation data belonging to the user. It does not modify, delete, execute code, or create financial obligations. While the server context includes write operations (booking) and snipe functionality, this specific tool only retrieves information. The blast radius is minimal—misuse by an AI would only expose the user's own reservation schedule.
From the tool's definition Tool name 'list_reservations' and description 'View your upcoming reservations' indicate a retrieval operation with no side effects. The verb 'view' and the passive data retrieval nature confirm this is a read-only action.
