python skills/flightclaw/scripts/search-flights.py LHR JFK 2025-07-01
python skills/flightclaw/scripts/search-flights.py LHR JFK 2025-07-01 --cabin BUSINESS
python skills/flightclaw/scripts/search-flights.py LHR JFK 2025-07-01 --return-date 2025-07-08
python skills/flightclaw/scripts/search-flights.py LHR JFK 2025-07-01 --stops NON_STOP --results 10
# Multiple airports (searches all combinations)
python skills/flightclaw/scripts/search-flights.py LHR,MAN JFK,EWR 2025-07-01
# Date range (searches each day)
python skills/flightclaw/scripts/search-flights.py LHR JFK 2025-07-01 --date-to 2025-07-05
# Both
python skills/flightclaw/scripts/search-flights.py LHR,MAN JFK,EWR 2025-07-01 --date-to 2025-07-03

Arguments:

  • origin - IATA airport code(s), comma-separated (e.g. LHR or LHR,MAN)
  • destination - IATA airport code(s), comma-separated (e.g. JFK or JFK,EWR)
  • date - Departure date (YYYY-MM-DD)
  • --date-to - End of date range (YYYY-MM-DD). Searches each day from date to date-to inclusive.
  • --return-date - Return date for round trips (YYYY-MM-DD)
  • --cabin - ECONOMY (default), PREMIUM_ECONOMY, BUSINESS, FIRST
  • --stops - ANY (default), NON_STOP, ONE_STOP, TWO_STOPS
  • --results - Number of results (default: 5)

Track a Flight

Add a route to the price tracking list and record the current price. Supports multiple airports and date ranges (creates a separate tracking entry for each combination).

python skills/flightclaw/scripts/track-flight.py LHR JFK 2025-07-01
python skills/flightclaw/scripts/track-flight.py LHR JFK 2025-07-01 --target-price 400
python skills/flightclaw/scripts/track-flight.py LHR JFK 2025-07-01 --return-date 2025-07-08 --cabin BUSINESS
# Track multiple airports and dates
python skills/flightclaw/scripts/track-flight.py LHR,MAN JFK,EWR 2025-07-01 --date-to 2025-07-03 --target-price 400

Arguments:

  • Same as search-flights, plus:
  • --target-price - Alert when price drops below this amount

Check Prices

Check all tracked flights for price changes. Designed to run on a schedule (cron).

python skills/flightclaw/scripts/check-prices.py
python skills/flightclaw/scripts/check-prices.py --threshold 5

Arguments:

  • --threshold - Percentage drop to trigger alert (default: 10)

Output: Reports price changes for tracked flights. Highlights drops and alerts when target prices are reached.

List Tracked Flights

Show all flights being tracked with current vs original prices.

python skills/flightclaw/scripts/list-tracked.py

MCP Server

FlightClaw also runs as an MCP server with extended search capabilities:

pip install flights "mcp[cli]"
claude mcp add flightclaw -- python3 server.py

MCP tools: search_flights, search_dates, track_flight, check_prices, list_tracked, remove_tracked

Additional MCP filters: passengers (adults/children/infants), airline filter, price limit, max flight duration, departure/arrival time restrictions, layover duration, sort order, and cheapest-date calendar search.

Currency

Prices are returned in the user's local currency based on their IP location. The currency is auto-detected from the Google Flights API response and displayed with the correct symbol (e.g. $, £, ฿, €). Tracked flights store the currency code in tracked.json.

Data

Price history is stored in skills/flightclaw/data/tracked.json and persists via R2 backup.
