One-way flight search with Claude

The agent searches live Google Flights data and answers with fares it can actually judge: every result carries Google’s historical price band and a low | typical | high verdict, so “is the price any good” is a field read, not a guess. The buy_link hands the user a working booking deep link.

Step 1 · Connect

Add the MCP server as a connector

Settings → Connectors → Add custom connector, paste the URL. If your client supports custom headers, prefer sending the key as x-rapidapi-key instead of in the URL.

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

Bring your own RapidAPI key: every request is billed to your own subscription, never ours.

Step 2 · Ask it

The prompt

Verbatim: paste it, or anything shaped like it. The agent maps it to the call below.

“Find me a nonstop JFK to Cancun flight on January 1 and tell me if the price is any good.”

Step 3 · Under the hood

What the agent calls

No glue code: the agent reads the tool schema, picks the tool, and fills these parameters from your prompt.

tool call
// search_oneway_flights
{
  "from_airport": "JFK",
  "to_airport": "CUN",
  "departure_date": "2027-01-01",
  "max_stops": 0,
  "limit": 5
}

Step 4 · Read the response

Fields your logic reads

The response is flat JSON. These are the fields this recipe branches on, with what each one means.

pricestring

The fare as Google Flights displays it: “$56”. The numeric twin price_as_number rides alongside for sorting and arithmetic.

price_insights_lownumber | null

The bottom of Google’s historical price band for this route and dates. Null when Google doesn’t publish a band: treat the fare as unjudged, not bad.

price_insights_highnumber | null

The top of the band. A fare above it is expensive for the route by Google’s own history.

price_range_in_relation_to_other_periods"low" | "typical" | "high" | null

Google’s verdict on the current fare against that band, the single field alerting, ranking, and “book now” logic branch on.

buy_linkstring (URL)

A Google Flights deep link that reopens this exact itinerary. Hand it to the user; it just works.

Questions, answered plainly

Is my key billed to me?
Yes. The MCP server is bring-your-own-key: Claude sends your RapidAPI key with each call and usage meters against your own subscription on RapidAPI. There is no FlightPowers account and no second bill.
Does this need a server of mine?
No. The MCP servers are hosted at flights.flightpowers.com and hotels.flightpowers.com: you add a URL to Claude, not a deployment.
What does it cost?
The Google Flights Live API's free tier is 10 requests/month with a hard cap: enough to verify your key works, not to evaluate. The PRO plan is $10/month for 2,500 requests, and every plan includes every endpoint.
