Duffel Flights & Stays MCP server for AI agents.

actionlake is an MCP gateway: one remote MCP server that connects Claude and other MCP clients to Duffel Flights & Stays and the rest of your systems. It gives your agent 103 Duffel Flights & Stays actions (63 reads, 26 writes and 14 that wait for a confirmation) and holds the Duffel Flights & Stays credential itself, so the agent never does. It paces Duffel Flights & Stays's limits and records every call.

100,000 free calls a month. No card, no email, no password: press Start a free sandbox on the next screen and keep the key it shows you.

Questions

The Duffel Flights & Stays MCP server, answered.

Is there a Duffel Flights & Stays MCP server for Claude?

Yes. actionlake is an MCP gateway: a remote MCP server that gives Claude, or another MCP client, 103 Duffel Flights & Stays actions across orders, customer user groups, offers and stay bookings, through the same eight tools it uses for every other connector. actionlake is independent; it is not made or endorsed by Duffel Flights & Stays.

What do I need to connect Duffel Flights & Stays?

Duffel access token. The free call account { op: "connections.requirements", service: "duffel" } lists exactly what to paste.

Can an AI agent delete or change things in Duffel Flights & Stays?

Only if its key allows it, and only with an explicit confirmation. 14 Duffel Flights & Stays actions are destructive, including delete a webhook, create an order and create a payment. Each runs only with confirm: true. Under the human confirm policy, or an approval rule on the key, the run waits until a named person approves it.

Will an AI agent use up my Duffel Flights & Stays API limit?

actionlake paces every call to the limits in the Duffel Flights & Stays service file: 120 calls a minute per connection. Repeated reads are answered from cache (56 Duffel Flights & Stays actions can be), which never reaches Duffel Flights & Stays.

What does a Duffel Flights & Stays action cost?

One upstream call, the only unit actionlake bills. A list that pages bills one call per page (20 Duffel Flights & Stays actions page). Cache hits, searches, dry runs and calls Duffel Flights & Stays refused with 401, 403, 429 or a 5xx are free. The Free plan includes 100,000 calls a month with no card. Paid plans start at US$49 a month for 250,000 calls, with overage from US$0.30 down to US$0.18 per 1,000.

Which Duffel Flights & Stays API does it cover?

The Duffel (flight search, offers, orders, changes, cancellations, payments, stays, cars, customers, webhooks) API v2 (Duffel-Version: v2) at api.duffel.com. It is built from Duffel Flights & Stays's documentation as read on 23 October 2026. 103 actions in 41 areas, each one in the signed service file (version 1.0.0).

Does actionlake keep my Duffel Flights & Stays data, and where?

actionlake processes and stores data in Sydney, Australia; there is no US region yet. Reads may be cached for up to 5 minutes, and a write clears the reads it affects. Each run's request and response is kept, sealed, for your plan's trace window: 1 day on Free, 3 days on Starter, 7 days on Pro, 14 days on Team, 30 days on Business and 30 days on Enterprise. Your Duffel Flights & Stays credential is sealed under your tenant's key, never logged and never returned. Your traffic is not used to train models.

Which AI clients can use it?

Claude Code, tested by us end to end, and the Claude app as a custom connector, tested by us with an existing key. Other MCP clients that support remote servers over Streamable HTTP (MCP revisions 2025-06-18 and 2025-11-25) and OAuth dynamic client registration, or a bearer header, should connect the same way; we have not tested them. Or plain REST, under the same action names.
