Is there a free flights MCP?

Yes, free-trial.flightpowers.com/mcp: sign in with Google and you get the same flight and hotel tools with no key, 50 searches a day and 250 a month, with one labelled sponsored card on each result. It is the place to try the tools. For anything you ship, use the ad-free server on this page with your own RapidAPI key.

What does a search cost on my key?

One date and destination combination is one request on your RapidAPI plan. The run on this page covered 3 departure dates and 2 destinations, so it billed 6. PRO is $10 for 2,500 searches a month; BASIC is free with 10 a month, enough to check the setup works.

Can it search a whole month?

Yes, in one call. departure_date_from and departure_date_to set the range and nights takes a list of trip lengths, so a month at three trip lengths is one tool call that prices 93 combinations. The server says how many it searched in search_coverage.

Does it book flights?

No. Every fare carries a buy_link that opens Google Flights on that itinerary, and the booking happens there.

Flights MCP

Google Flights MCP server for Claude, Cursor and ChatGPT

FlightPowers' Google Flights MCP server gives Claude, Cursor and ChatGPT live Google Flights fares with Google's own low / typical / high price band, a date range and a list of destinations in one call, and a round trip priced as one request with one booking link. Free with ads at free-trial.flightpowers.com/mcp (Google sign-in, 50 searches a day); ad-free on your own RapidAPI key, where PRO is $10 for 2,500 searches. Best for fare tracking, date scans and AI agents; it does not book.

Also called a flights MCP, a flight search MCP or a flight MCP server. It is hosted: you add a URL, nothing runs on your machine.

Get a flights key →Connect it

add this URL to your MCP client

https://flights.flightpowers.com/mcp

Your client shows a Sign in button. Sign in with Google; your first 10 searches each day run free and ad-free with nothing pasted, and you paste your RapidAPI key once on the page that opens when you want more.

Is there an MCP for flights?

Yes. FlightPowers runs a hosted flights MCP server at flights.flightpowers.com/mcp: add the URL to Claude, Cursor, ChatGPT or any MCP client, sign in with Google, and the assistant can search live fares one-way or round trip.

Is there an MCP for Google Flights?

Google has offered no public flights API since QPX Express closed in 2018, so a Google Flights MCP reads the live public results. This one hands them to the assistant with a booking link on every fare and Google's own low / typical / high price band for the route.

What is an MCP server for?

An MCP (Model Context Protocol) server gives an AI assistant tools it can call. A flights MCP lets the assistant fetch real fares when you ask, instead of guessing from what it was trained on.

One real search

Six round trips priced in one tool call

New York to Lisbon or Barcelona, leaving any day from November 10 to 12, five nights. I sent this call to flights.flightpowers.com/mcp on 2026-10-06 at 19:54 UTC; it is the call an assistant makes for that question. It came back in about 4 seconds and billed 6 requests.

To	Out → back	Airlines	Total	Google's range	Verdict

Lisbon (LIS)	11-10 → 11-15	British Airways	$668	$425 to $700	typical

Each row is a whole round trip: both legs, one total, one buy_link. The cheapest was Barcelona (BCN) at $564, which Google marks typical for that route (its range $385 to $650). I asked for 5 rows; the server raised the limit to 6 so every date and destination it searched gets a row, and says so in search_coverage. Fares move by the minute, so read this as a captured run, not a price you can book today.

search_roundtrip_flights

use_fallback	Leave unset. Switches the search to a second, independent flight data source instead of the usual Google Flights page read.

idempotentHint is false on purpose: a fare search is a live lookup, and a client that caches it would hand you an old price.
