Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| get_businessA | Look up a business on Vitta by its booking link or slug. Returns the services it offers (with service_id, duration and price in BRL), opening hours, address, contact and whether it's taking online bookings. Call this first: the other tools need a service_id from here. |
| find_available_slotsA | List the start times a business would offer for one service on its own booking page, grouped by day, in the business's time zone. Only these exact times can be booked: don't invent, round or shift them, and pass starts_at to book_appointment unchanged. Times change as other people book, so look again if the person takes a while to decide. |
| book_appointmentA | Book a service for the customer account configured on this server. Only call this after the person has explicitly confirmed the business, service, day, time and price. starts_at must be copied exactly from find_available_slots. If no customer account is configured, this returns a booking link to hand to the person instead. |
| list_my_appointmentsA | List the appointments of the customer account configured on this server, across every Vitta business, soonest first. By default only upcoming pending or scheduled ones. Use it to answer "when is my appointment?" and to get the appointment_id for cancel_appointment. |
| cancel_appointmentA | Cancel one of the configured customer's upcoming appointments. The time goes back to other people and this can't be undone, so confirm with the person first. Get appointment_id from list_my_appointments. |

Each tool targets a distinct step of the booking lifecycle: business lookup, availability discovery, booking, listing the user's appointments, and cancellation. There is no overlap or risk of misselection, and descriptions explicitly state prerequisites (service_id, appointment_id, starts_at).
All names follow a consistent verb_noun snake_case pattern (get_business, list_my_appointments, find_available_slots, book_appointment, cancel_appointment). Verbs are distinct and predictable throughout.
Five tools map cleanly onto the minimal end-to-end booking flow, with each tool earning its place. Nothing feels padded or thin for a single-purpose booking server.
The core lifecycle (discover business → check availability → book → list → cancel) is fully covered with no dead ends. Minor gaps remain: no reschedule/update appointment and no business search by name or location, though agents can work around these.
