Free Flight Search + Hotel Search MCP — Google Flights & Booking.com, no API key

FlightPowers is a travel data API for developers and AI agents: live Google Flights fares with Google's own low / typical / high price band and a round trip priced as one request, plus live Booking.com hotel rates. This is its free MCP server: no API key, sign in with Google and you get 50 searches a day and 250 a month, paid for by one clearly-labeled sponsored card. The same tools run ad-free on your own RapidAPI key, where PRO is $10 for 2,500 flight searches, about a sixth of SerpApi's price per search (their cheapest plan is $25 for 1,000). Best for price tracking, date scans and AI agents; it does not book.

Google Flights fares and Booking.com hotel prices in one server: cheap-flight discovery across flexible dates, hotel availability by city or by name, review scores and booking links.

Funded by a single, clearly-labeled sponsored card inside the result widget.

Ask for flights and hotels in the same conversation. Four tools, one server, nothing to configure.

✈️ Flights — Google Flights

Every result carries Google's own price band (price_insights_low / price_insights_high) and a low / typical / high verdict — so the answer is "$71 is typical for this route", not just "$71".

🏨 Hotels — Booking.com

All four tools are annotated read-only. They search and read; they cannot book, hold, pay for or cancel anything.

What the free tier costs you

Nothing in money. Two limits in behaviour:

A date missing from departure_dates_searched was never searched — which is not the same as having no flights. Check that list before concluding a date is empty.

Upgrading — what you actually get

→ ✈️ Flights: mrabi/google-flights → 🏨 Hotels: mrabi/booking

Free tiers available on both — subscribe at rapidapi.com/mtnrabi.
