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.
