Cheap Flights Alert in ChatGPT, Claude and other AI assistants
Ask your AI assistant for today's cheapest flights from your airport. The Cheap Flights Alert connector looks up the round-trip fares we track and tells you which ones are far below the usual price, with travel dates and a booking link.
Connector address
https://cheapflightsalert.com/api/mcp
It is a remote MCP server. When you connect it, you sign in with your free Cheap Flights Alert account (we email you a sign-in link) and allow the assistant to use it. The tools read fare data and never book or charge anything.
ChatGPT

Your data
When you connect it, you sign in with your Cheap Flights Alert account, so requests are linked to that account. The connector receives what the assistant sends with each request (airports, destinations, price limits), never your chat history, and it cannot book or pay for anything. Prices can change; the booking site always has the final price. Booking links are partner links and we may earn a commission at no extra cost to you.
