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

,

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
