Is my key billed to me?

Yes. The MCP servers are bring-your-own-key: ChatGPT sends your RapidAPI key with each call and usage meters against your own subscription. There is no FlightPowers account and no second bill.

Where does my key live?

On the connector URL, stored in your ChatGPT settings: it is configuration, not conversation. Treat the URL as a secret: anyone who has it can spend your quota.

Which plan do I need?

The free tier is 10 requests/month with a hard cap: enough to verify the connector works, not to use it. For day-to-day use, the $10 PRO plan (2,500 requests/month on flights) is the realistic floor. Every plan includes every endpoint.

Custom MCP connectors in ChatGPT are added through its developer-mode connector settings. Nothing about the server itself is experimental: the same URL serves Claude, Cursor, and any other MCP client.

Can I try it before adding a key?

Yes. The live demo on the homepage and the free tools on this site run real requests on our key, so you can see the exact responses ChatGPT will get before you subscribe.

Integrations

Live flight & hotel data in ChatGPT

ChatGPT’s developer-mode connectors speak MCP. One URL connects it to live Google Flights and Booking.com data, billed to your own key, judged by Google’s own price band.

Google's price band + a low | typical | high verdict on every fare
Bring your own key: usage bills to your own RapidAPI plan, never ours
Live Booking.com rates too, with proxy_country per-market pricing

Free tier: 10 requests/month. No card to try.

add as a connector (developer mode)

https://flights.flightpowers.com/mcp?rapidapi_key=YOUR_RAPIDAPI_KEY

Settings → Connectors (developer mode) → add the server URL. The key rides on the server URL; ChatGPT never sees it in chat.

Connect

Add the MCP server as a connector

1
Get a RapidAPI key
Subscribe on the listing’s pricing tab. The free tier needs no card. The key is the only credential this integration uses.
2
Add the connector in developer mode
Settings → Connectors, enable developer mode, and add the server URL above with your key in place of YOUR_RAPIDAPI_KEY. For hotels, add https://hotels.flightpowers.com/mcp the same way. One RapidAPI key covers both once you subscribe to each listing.
3
Use it in a chat
The flight and hotel tools become available in conversations. The key rides on the server URL in your settings. ChatGPT never sees it in the chat itself.

Ask it

Five things to say, verbatim

ChatGPT picks the tool and fills the parameters itself: these all work as written.

“Is $480 for LHR to JFK in mid-October a good price, or should I wait?”

“Find me the cheapest nonstop from Berlin to Paris in the second week of June.”

“Round trip JFK to London, out September 22, back September 29. Rank the options by value, not just price.”

“Find a hotel in Tokyo Shibuya for November 3 to 7, 2 adults, breakfast included.”

“Compare what the same room at the Kremlin Palace in Antalya costs when booked from Germany versus the US.”

Tool inventory

The four tools ChatGPT sees

Printed raw on purpose: this page is written to be read by an agent as much as by a person.

search_oneway_flightsflights server

One-way fares with Google’s price band, the low | typical | high verdict, and a buy_link on every result. Takes a single date or a date range, expanded server-side.

search_roundtrip_flightsflights server

Paired-leg round-trip itineraries: one object per option with both legs matched and a combined total_price.

search_hotelshotels server

Destination search over live Booking.com rates, with the site’s own filters: review_score_8, free_cancellation, and the rest.

find_hotel_by_namehotels server

One property by the name a human would type. proxy_country prices it from any market, the rate-parity tool.
