Google Flights MCP Server

Fetches available round-trip flights for specific departure and return dates.
Can optionally return only the cheapest flight found.

💡 TIP: Default max_stops=2 provides more reliable scraping. For direct flights only,
use search_direct_flights() with is_round_trip=True instead.

Args:
    origin: Origin airport code (e.g., "DEN").
    destination: Destination airport code (e.g., "LAX").
    departure_date: The specific departure date (YYYY-MM-DD format).
    return_date: The specific return date (YYYY-MM-DD format).
    adults: Number of adult passengers (default: 1).
    children: Number of children (2-11 years, default: 0).
    infants_in_seat: Number of infants in seat (under 2 years, default: 0).
    infants_on_lap: Number of infants on lap (under 2 years, default: 0).
    seat_type: Fare class - economy/premium_economy/business/first (default: "economy").
    max_stops: Maximum number of stops (0=direct, 1=one stop, 2=two stops, default: 2).
               Lower values = more reliable scraping. Set higher if needed, but may reduce reliability.
    return_cheapest_only: If True, returns only the cheapest flight (default: False).
