Google Flights Search (Real-Time Fares) MCP Server

FlightPowers one-way fare search: live prices read from Google Flights. Input: origin and destination IATA codes -- the destination may be several codes, as "BCN,LIS,ATH" or ["BCN","LIS","ATH"] -- plus either one departure date or a date range. Returns each flight's price, airline, duration, stops, a bookable buy_link, and Google's historical price range (price_insights_low / price_insights_high) so you can say whether a fare is actually a good deal. Use it for any one-way fare question, including open-ended ones. For a flexible search make ONE call with a date range and/or several destinations -- do NOT call it once per date. 'Cheapest flight to Sri Lanka anywhere in October' is one call, not thirty. Each date/destination combination is one billed request; the count and the plan's remaining quota come back in `api_usage`. `by_destination` carries one entry per destination you asked for -- empty ones included, each with a `reason` -- so read it before telling a user a destination has no flights. Requires the caller's own RapidAPI key for the Google Flights Live API. Get one (free tier available) at https://rapidapi.com/mtnrabi/api/google-flights-live-api, then pass it as an `x-rapidapi-key` header (preferred), a `?rapidapi_key=` query parameter on the server URL, or your client's own API key field -- first non-empty wins. Usage counts against the caller's own RapidAPI plan, not ours; every response reports what it spent and what is left in `api_usage`. No key? Sign in with Google and the first 10 searches each day are free on this server -- ad-free, nothing to paste.

FlightPowers round-trip fare search: live prices read from Google Flights, priced as paired legs rather than two separate one-ways. Input: origin and destination IATA codes -- the destination may be several codes, as "BCN,LIS,ATH" or ["BCN","LIS","ATH"] -- a departure date or range, and either a return date or a trip length in nights. Returns the total price for both legs, per-leg airline, stops and duration, and a single bookable buy_link for the trip. Use it for any return-trip fare question. For a flexible search make ONE call: pass departure_date_from / departure_date_to for the outbound range and `nights` instead of return_date to compare trip lengths -- '5 to 7 nights in Rome sometime in May' is one call. A WHOLE MONTH is one call too. departure_date_from "2026-10-01", departure_date_to "2026-10-31" and nights [3, 4, 5] prices every departure day in October at three trip lengths and tells you which combination is cheapest. That is 93 date/night combinations and the cap rises to cover them by itself -- do not narrow the question to make it fit, and do not split it into several calls. Each date/night/destination combination is ONE request billed to the caller's plan, so a month at three trip lengths costs 93 of them and the same month across two destinations costs 186. Say that number before running a search that large if the user has not asked for it in so many words. A search that fails with a server error is retried once and RapidAPI bills the retry, so the figure to quote back is `api_usage.hub_requests_billed` (what the plan was actually charged), not the combination count. Both come back in `api_usage`, with the plan's remaining quota. `by_destination` carries one entry per destination you asked for -- empty ones included, each with a `reason` -- so read it before telling a user a destination has no flights.
