## MCP tools (4)

### `find_salons` (~214 tokens)

Find nail salons

Nail salons on Lacquer in a US city + state or ZIP code, optionally narrowed by salon name. Up to 20 per call; "total" says how many match, and "offset" pages through the rest. Salons that take online bookings ("books_online": true) come first; a salon with books_online false has no open times online and is listed with its phone number. Within that, Lacquer partner salons ("partner": true) come first; the rest rotate daily, and the order says nothing about quality.

Input parameters:

- `city` (string): City, e.g. "Santa Monica". Used together with state.
- `limit` (integer)
- `name` (string): Part of the salon's name.
- `offset` (integer): Number of results to skip; a result's next_offset gives the next page.
- `state` (string): US state, "CA" or "California".
- `zip` (string): 5-digit ZIP code. Used instead of city/state when given.

### `get_salon` (~41 tokens)

Salon details and menu

A salon's address, phone, weekly hours and full service menu (service_id, price, duration).

Input parameters:

- `slug` (string, required): The salon's slug.

### `check_availability` (~105 tokens)

Open appointment times

Open start times for one service with any technician, each as an ISO start_at and a local label. Searches from now when no date is given; up to 7 days.

Input parameters:

- `date` (string): YYYY-MM-DD in the salon's local time.
- `days` (integer): How many days from date. Default 1.
- `service_id` (string, required): The service's id on the salon's menu.
- `slug` (string, required): The salon's slug.

### `book_appointment` (~176 tokens)

Book an appointment

Books an appointment. Real and immediate: the salon holds the time and the customer gets a confirmation text. It can't be cancelled or changed online, only by calling the salon. Repeating the same call returns the same booking, never a second one.

Input parameters:

- `agent_name` (string): Name of the AI assistant making the booking, e.g. "Claude". The salon sees "Booked by <agent_name>".
- `customer_name` (string, required): The customer's name, as the salon should greet them.
- `customer_phone` (string, required): The customer's mobile number; the confirmation text goes here.
- `service_id` (string, required): The service's id on the salon's menu.
- `slug` (string, required): The salon's slug.
- `start_at` (string, required): ISO start time of an open slot for this salon and service.
