## MCP tools (3)

### `search_flights` (~364 tokens)

Search flight prices and options on Google Flights.

Args:
    destination: Destination airport IATA code (e.g. "GRU"). If you only
        have a city name, call airport_search first.
    departure_date: Outbound date, YYYY-MM-DD.
    origin: Origin airport IATA code. Defaults to Lisbon (LIS) if omitted.
    return_date: Return date YYYY-MM-DD to search a round trip; omit for
        one-way. For round trips, each result's price is Google's
        estimated round-trip total for that outbound flight paired with
        its cheapest matching return — stops/duration/legs describe the
        outbound only. Open booking_link to pick the exact return flight.
    adults: Number of adult passengers (default 1).
    children: Number of child passengers (default 0).
    infants: Number of lap infants, under 2 with no own seat (default 0).
    cabin_class: "economy" | "premium" | "business" | "first".
    currency: ISO currency code. Defaults to EUR.
    max_stops: Maximum stops to allow (0 = nonstop only, 1 = up to one
        stop, etc.). Omit to allow any number of stops.
    sort_by: "price" (default, ascending) or "duration" (ascending).

Input parameters:

- `adults` (integer)
- `cabin_class` (string)
- `children` (integer)
- `currency` (string)
- `departure_date` (string, required)
- `destination` (string, required)
- `infants` (integer)
- `max_stops`
- `origin` (string)
- `return_date`
- `sort_by` (string)

### `cheapest_dates` (~308 tokens)

Find the cheapest day(s) to fly within a date window (price-calendar style).

Runs one search per candidate departure day in the window (capped at 21
days — neither of this server's data sources expose a real bulk
price-calendar endpoint) and returns each day's cheapest fare, sorted by
price ascending.

Args:
    destination: Destination airport IATA code.
    start_date: First candidate departure date, YYYY-MM-DD.
    end_date: Last candidate departure date, YYYY-MM-DD (inclusive; max
        21 days after start_date).
    origin: Origin airport IATA code. Defaults to Lisbon (LIS).
    trip_length: Nights for a round trip, applied to every departure day
        in the window. Omit to price one-way fares.
    adults, children, infants: Passenger counts (see search_flights).
    cabin_class: "economy" | "premium" | "business" | "first".
    currency: ISO currency code. Defaults to EUR.
    max_stops: Maximum stops to allow. Omit to allow any.

Input parameters:

- `adults` (integer)
- `cabin_class` (string)
- `children` (integer)
- `currency` (string)
- `destination` (string, required)
- `end_date` (string, required)
- `infants` (integer)
- `max_stops`
- `origin` (string)
- `start_date` (string, required)
- `trip_length`

### `airport_search` (~78 tokens)

Resolve a city or airport name to IATA code(s), e.g. "Lisbon" -> LIS.

Args:
    query: A city name, airport name, or 3-letter IATA code.
    limit: Maximum number of matches to return (default 5).

Input parameters:

- `limit` (integer)
- `query` (string, required)
