Recipe · Flights API
Price-insights check with Cursor
The recipe that only this API can run: the agent compares a quoted fare against Google’s own price band for the route and dates. Below the band’s low end → take it; above the high end → wait. The verdict field gives the agent a defensible recommendation with a source.
Free tier on RapidAPI. No card to try.
Step 1 · Connect
Add to .cursor/mcp.json
Restart Cursor. It hits the 401, registers itself, and offers you the sign-in: Add the URL, click Sign in, sign in with Google, and paste your RapidAPI key once on the page that opens. One URL, whichever way you connect. The same shape works in any mcp.json-style client. For scripts, CI and clients without a sign-in button, keep the same URL and add a header instead: { "mcpServers": { "flights": { "url": "https://flights.flightpowers.com/mcp", "headers": { "x-rapidapi-key": "YOUR_RAPIDAPI_KEY" } } } }
{
"mcpServers": {
"flights": { "url": "https://flights.flightpowers.com/mcp" }
}
}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.
“I was quoted $129 for JFK→Cancún on January 1. Should I take it?”
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.
// search_oneway_flights
{
"from_airport": "JFK",
"to_airport": "CUN",
"departure_date": "2027-01-01",
"limit": 3
}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.
price_insights_lownumber | nullThe 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 | nullThe 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" | nullGoogle’s verdict on the current fare against that band, the single field alerting, ranking, and “book now” logic branch on.
Questions, answered plainly
- Is my key billed to me?
- Yes. The MCP server is bring-your-own-key: Cursor 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 Cursor, 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.
