Connect FlightSweeper to ChatGPT
Use FlightSweeper as ChatGPT's owner-scoped flight search, quote, approval, and booking-state backend without exposing passenger or payment data.
OAuth setup supported
ChatGPT connects to FlightSweeper with OAuth authorization code, PKCE, rotating refresh tokens, and an owner-scoped access token. The client never receives passenger identity or payment data.
Travelers who want to plan and compare flights in ChatGPT, then approve and pay on FlightSweeper.
Use FlightSweeper to compare live flights for this trip. Show the all-in total, quote time, expiry, refund terms, and refresh state. Create a booking intent only after I choose.
Setup flow
Every client uses the same Streamable HTTP endpoint and the same nine public tools. Booking intents return canonical state; approval and payment stay hosted.
FlightSweeper publishes OAuth discovery and Dynamic Client Registration. OAuth access tokens expire after 10 minutes, refresh tokens rotate, and the connection can be revoked from FlightSweeper.
Open ChatGPT connector settings and add a custom MCP connector.
Enter https://flightsweeper.com/api/agent/mcp as the remote server URL.
Sign in to FlightSweeper and approve the requested OAuth access.
Confirm ChatGPT discovers exactly nine FlightSweeper tools before the first live search.
Keep passenger entry, quote approval, and payment on the FlightSweeper-hosted handoff.
Tool permissions
Every client should keep the same transaction boundary: search can happen in the agent, but booking happens after the traveler confirms a hosted checkout page.
