Free travel-data tools
Real results before we ask you for anything. Two of these we give away whole: the search engine, and an MCP server your assistant can use with no API key at all.

FlightPowers Search

Free MCP Server
“Live fares inside your own assistant”
Paste one URL into Claude or ChatGPT, sign in with Google, and it can search live Google Flights fares and Booking.com room rates for you, in the chat you are already in. Free because it is ad-supported.

No API key
Connect the free MCP server in two steps
Paste the address, sign in with Google, and your assistant has four live travel tools. There is no API key to find and nothing to configure.
Settings → Connectors → Add custom connector. Paste the URL and save, then click Sign in and sign in with Google. The four tools appear in a new chat. No key anywhere.
https://free-trial.flightpowers.com/mcpHow it stays free
It is ad-supported. Plainly.
You do not pay for this server, so an advertiser does. Every successful result comes back with one sponsored card, always labelled Sponsored, served through our ad partner Lulu. It renders as a card in clients that support MCP UI panels and as a plain bordered block in terminal clients, so you will see it either way. We would rather you read that here than discover it in your chat window.
Two things it never does: attach an ad to an error or to a search that found nothing, and pass Lulu your identity.
The keyed servers at /mcp carry no ads at all. Same data, your own RapidAPI key, billed to your own plan.
The four tools you get
Flights and hotels, both, on the free server. These names and shapes were read from a live tools/list against the address above.
search_oneway_flightsLive one-way fares with Google’s price band and a low | typical | high verdict, plus a bookable buy_link. Takes a date range and a list of destination airports in one call.
search_roundtrip_flightsRound trips priced as paired legs, not two stapled one-ways. Takes a departure range and a nights value to compare trip lengths in one call.
search_hotelsLive Booking.com results for a destination and a stay: price, review score, room type, and a working booking link. One stay per call.
find_hotel_by_nameAvailability and price for one named property. Takes the name a person would type; no internal property ID needed.
What the free server will not do
Worth knowing before you point anything at it. These are the free server's own limits, not the API's.
- One call searches at most 15 date × destination combinations
- Ask for a wider range and the request is not rejected: the server samples the range evenly, returns
truncated: true, and lists exactly which dates it searched insearch_coverage.departure_dates_searched. A date missing from that list was never searched, which is not the same as having no flights. The keyed servers go to 30 combinations per call, with amax_searchesargument to cap the spend, and each combination is one billed request on your own plan. - 50 searches a day, 250 a month, per person
- The caps run against the Google account you signed in with, and one call spends one search per date × destination combination, so a wide search costs more than one. Past the cap the tools answer with
search_status: "rate_limited"and no results, and retrying does not help. On top of that, everyone shares one daily backend budget, and when it runs low the server narrows its search rather than failing. That is why this is for trying it and for personal use rather than for anything you ship. - The hotel tools take one stay per call
- No date range and no destination list on
search_hotelsorfind_hotel_by_name: price several dates or properties with one call each. Two controls are keyed-server only, and the free server does not expose them at all: the per-country pricing that rate-parity monitoring is built on (price_as_seen_from) and the documented Booking.comfilters.

All 6 run real searches on our key, so they're capped per visitor per day; the pages say exactly how.
Every route and city page
180 pages, one per question worth asking
Each of these is one of the tools above, pre-filled and with the facts of that route or destination beside it. The routes are the city pairs in the published tables of the world's busiest air routes, plus three New York to Europe routes we scan for fares ourselves; the cities are the top 30 by international visitors. We build a page where there is a real question behind it, and nowhere else.
