Q: How do we verify final ticket pricing before booking?

Your agent executes priceoffer against a specific offer ID. This checks live carrier inventory to confirm the final fare and available services before you call the booking tools.

Team-wide flight integrations in VS Code Copilot

The Duffel MCP server provides your engineering team with direct access to global flight inventories inside VS Code Copilot. Developers use `create_offer_request` to pull real-time flight schedules and prices directly into the chat interface. By committing the configuration, your entire team can run `list_offers` to inspect carrier payloads. This ensures everyone develops against identical live travel data structures.

Validate accommodation flows during development

This MCP Server enables your development team to test hotel search logic within their shared workspace. The agent runs `search_stays` and `fetch_stay_rates` to verify room availability and pricing against live lodging databases. Developers can test reservation pipelines by triggering `quote_stay` and `book_stay` in sandbox mode. This lets your team debug booking states without leaving their primary editor.

Verify order state transitions and payments

This integration lets you debug complex payment and order states directly in your workspace. Your agent runs `create_payment` to settle held orders and calls `get_payment` to verify the transaction status. If you need to test cancellation or modification paths, the agent executes `change_order` or `cancel_order` directly. You can inspect the API responses in real-time to ensure your payment flows are working.
