The ChatGPT setup for the ancillary shelf

Ancilair is an MCP server for ChatGPT. One token reaches the travel extras on the shelf: insurance, eSIM, lounges, bags, fast track, transfers, hotels, visas, disruption, and seats and bags beside a ticket. Calls on Ancilair's account are metered at the supplier's rate, with 0% markup. The price is quoted on the call.

Your own supplier key is never metered. ChatGPT reads the price on the call, before anything is booked.

Install in ChatGPT

  1. 1

    In ChatGPT, send this in the chat: set up Ancilair — https://ancilair.com/llms.txt

  2. 2

    It reads https://ancilair.com/llms.txt and sets itself up. If it asks for a key, give it your team token (header X-Anc-Token, or Authorization: Bearer on https://mcp.ancilair.com).

  3. 3

    Ask for the job. The agent searches the catalog, tells you the price quoted on the call, and does not book, bind, order, purchase, add, or apply until you say yes. You do not hold a supplier key unless you registered one.

What ChatGPT can do now

By job. Where several suppliers do one job, they sit side by side and the choice is yours: the routed id, or a named supplier.

Sequences ChatGPT can run from one prompt

Several jobs, chained. Each step is quoted on the call. Nothing is booked until there is an explicit yes.

Insure a trip

A quote is not a policy. This is not insurance advice. Read the supplier's exclusions in the quote before you present it.

Try: “Using Ancilair, quote trip insurance for two travellers to Japan, departing 2026-11-02 and returning 2026-11-12. Read https://ancilair.com/llms.txt. Call anc.insurance.quote on https://api.ancilair.com. Show the quoted price and who answered in X-Anc-Served-By. Do not bind a policy until I say yes.”

Pick an eSIM

A plan list is not an activated eSIM. This is not telecom advice. Coverage on a plan is the supplier's description of that plan, quoted on the call.

Try: “Using Ancilair, list eSIM plans for France for 7 days. Read https://ancilair.com/llms.txt. Call anc.esim.plans on https://api.ancilair.com. Show the quoted price. Do not order until I say yes.”

celitech.esim.order The package the traveller accepted. Returns the activation code. Idempotency-Key required. Runs only after an explicit yes. Quoted on the call

Find a lounge

A search is not an entry pass. If the supplier has no slot at that terminal, the response says so and nothing is billed.

Try: “Using Ancilair, search lounges at CDG terminal 2E on 2026-10-14 for one adult. Read https://ancilair.com/llms.txt. Call anc.lounge.search on https://api.ancilair.com. Show the quoted price. Do not book until I say yes.”

gordian.lounge.book The lounge product the traveller accepted, added to that trip. Idempotency-Key required. Runs only after an explicit yes. Quoted on the call

Cover a delayed or lost bag

A quote is not a purchased guarantee. This is not insurance advice. This job is not an extra piece of airline baggage.

Try: “Using Ancilair, quote delayed-or-lost bag protection for this booking. Read https://ancilair.com/llms.txt. Call anc.bags.quote on https://api.ancilair.com. This is not an extra airline bag. Show the quoted price. Do not purchase until I say yes.”

Fast track and security

Book only where the supplier returns a slot. A search with no slot is an empty result, not a guess, and nothing is billed.

Try: “Using Ancilair, search fast track for the airport, date, and party I give you. Read https://ancilair.com/llms.txt. Call anc.fasttrack.search on https://api.ancilair.com. If there is no slot, say so. Do not book until I say yes.”

holidayextras.fasttrack.book That code, with the same party and time. Idempotency-Key required. Runs only after an explicit yes. Quoted on the call

Airport to address

A quote is not a car on the way. Private and shared rides are different products. Do not swap them after the quote.

Try: “Using Ancilair, quote an airport transfer for the pickup, drop-off, time, and party I give you. Read https://ancilair.com/llms.txt. Call anc.transfer.quote on https://api.ancilair.com. Show the quoted price. Do not book until I say yes. Do not swap a private ride for a shared one after the quote.”

Find a hotel

A search is a quote. It is not a reservation. If the confirmed price differs from the search, stop and show the new price. That price still needs a yes.

Try: “Using Ancilair, search hotels for the dates, place, and guests I give you. Read https://ancilair.com/llms.txt. Call anc.hotel.search on https://api.ancilair.com. A search is not a reservation. If the confirmed price differs, stop and show it. Do not book until I say yes. Do not shop flights.”

Supplier Tool What the call needs Price

nuitee.hotel.book The offer from that search, then the guest's name and email. Prebook runs first. If the confirmed price differs, the call returns that price and does not reserve the room. Idempotency-Key required. Runs only after an explicit yes. Quoted on the call
RateHawk ratehawk.hotel.search Check-in, check-out, guests per room, residency as passport country, and a place. For one chosen hotel, pass that hotel so the rooms are the hotel-page rates. Quoted on the call

Visas and entry rules

A requirements result is not a visa. Eligibility is not an approval. This is not legal or immigration advice. Rules change; the supplier response is the record for that call.

Try: “Using Ancilair, check entry rules for the nationality, origin, destination, and dates I give you. Read https://ancilair.com/llms.txt. Call anc.entry.rules on https://api.ancilair.com. A requirements result is not a visa. Do not call anc.visa.apply until I say yes to a specific product. This is not legal or immigration advice.”

CIBT (Entriva) cibt.visa.check Nationality, residency, destination, purpose of travel, entry date, exit date. Not an application. Quoted on the call

Disruption and delay

A quote is not cover. Compensation eligibility is not a promise that an airline or a regulator will pay. This is not legal or insurance advice.

Try: “Using Ancilair, quote disruption cover for the flight I give you. Read https://ancilair.com/llms.txt. Call anc.disruption.quote on https://api.ancilair.com. A quote is not cover, and an eligibility check is not a filed claim. Do not bind or open a claim until I say yes.”

collinson.smartdelay.register The flight the traveller accepted. Idempotency-Key required. Runs only after an explicit yes. Quoted on the call

Seat or bag beside the ticket

A map or a bag list is not a confirmed extra. Adding it runs only after an explicit yes, and the payment has to include the service price the supplier just returned.

Try: “Using Ancilair, show the seat map and extra bags beside this ticket. Read https://ancilair.com/llms.txt. Call anc.seat.map and anc.extrabag.list on https://api.ancilair.com. Do not search for flights. A Duffel call needs a Duffel offer or order id. Do not add a seat or bag until I say yes, and include the service price in the payment.”

Questions

Do I need a key from each supplier?

No. Ancilair makes the upstream request and relays the answer, so ChatGPT does not hold a supplier credential. If your team already pays a supplier, register that key and those calls are never metered.

What does a call cost?

The supplier's own rate, with 0% markup. The price is quoted on the call, in X-Anc-Cost-Micro. This page does not publish a rate card.

Does Ancilair pick the supplier?

A routed id uses the team's own contract first, then the cheapest quote that fits, and names who answered in X-Anc-Served-By. A named id runs that supplier and no one else.

Is a quote a booking?

No. Book, bind, order, purchase, add, or apply only after an explicit yes, with an Idempotency-Key. This is not legal, immigration, telecom, or insurance advice. Flights stay with the air API.
