WHAT IT DOES

What reservationTool does on Genkit MCP

AI agents use reservationTool to commit financial operations through Genkit MCP, usually the final step of a payment, billing, or trading workflow. A call moves real money.

RISK

Why reservationTool is rated Critical

Booking a reservation typically commits a financial obligation (e.g., hotel, restaurant, travel reservation) and may involve payment or cancellation penalties. The word 'book' implies a binding commitment. Classified as Financial due to the potential monetary obligation, though confidence is moderate since the description lacks specifics about payment involvement.
