Flights MCP Server

Give your AI agent live flight data. This is an MCP server: connect it once in Claude, Cursor, ChatGPT or any MCP client, and the agent can search fares, compare two sources, find the cheapest dates and the cheapest destinations — on its own, mid-conversation.

$0.03 per tool call. Nothing else — no run fee, no subscription, no fee for the rows behind the answer.

The four tools

Tool	What the agent can finally answer
search_flights	"How much is DPS–SIN on 15 March, business class, nonstop?" — live fares with airline, flight numbers, times, stops and Google's low/typical/high verdict
compare_flight_prices	"Find me the cheapest" — the same search on Google Flights and KAYAK, with which source won and by how much
cheapest_dates	"When is it cheapest to fly there?" — lowest fare for every day over up to a year, cheapest days first
cheap_destinations	"Where can I go from Bali for under $200?" — destinations with price, airline, stops and dates

Connect it

Claude Desktop / Claude Code / Cursor — add to your MCP config:

{
  "mcpServers": {
    "flights": {
      "url": "https://lergassy--flights-mcp-server.apify.actor/mcp",
      "headers": { "Authorization": "Bearer <YOUR_APIFY_TOKEN>" }
    }
  }
}

Any other MCP client — endpoint https://lergassy--flights-mcp-server.apify.actor/mcp, transport streamable HTTP, auth a Bearer token (your Apify API token from Settings → Integrations).

That is the whole setup. There is no server to host, no key to rotate, nothing to start by hand — the server wakes on the first call and sleeps when the conversation ends.

What it costs

$0.03 per tool call. A normal planning conversation makes three to six calls, so it lands around ten to twenty cents. There is no charge for how many flights come back: compare_flight_prices running two sources and returning sixty itineraries is the same $0.03 as a single-source lookup.

Failed calls are still calls — but a tool that cannot answer returns a short error to the agent instead of burning the conversation, and the underlying data has no separate bill.

Why an MCP server and not an API

An agent with an API needs you to write the glue: build the request, parse the response, handle the retries. An agent with this server just has four tools with self-describing arguments, so it picks the right one and fills the fields itself. The difference shows up in prompts like "we have a week in March and $400 — where should we go and when do we book?", which needs three of these tools in sequence and no code at all.

Example prompts once connected

• "Cheapest nonstop from Bali to Singapore in March, in USD — and is that a good price?"
• "Compare Google Flights and KAYAK for JFK–LHR on 15 March and tell me where to book."
• "When is the cheapest week to fly DPS–BKK in the next six months?"
• "Where can I fly from London for under £150 next month?"
• "Plan a two-week trip from Bali in March under $600 of flights — pick the destination and the dates."

Notes and limits

Prices are live and move during the day, so a quote is a quote for right now. Round-trip prices are the total for both directions. Tools read publicly displayed fares without logging in or collecting personal data; the sites' terms restrict automated access, and the legality of scraping public data depends on your jurisdiction and use.
