Jaunt inside ChatGPT & Claude

Ask ChatGPT or Claude to plan your trip with Jaunt’s live flights and hotels.

Connect Jaunt once and your assistant can search live fares, plan around your dates and book — checking with you first. Two steps to set up, then what to say.

Step 1: Have a Jaunt account

Your assistant connects to your own Jaunt account, so you’ll need one. New to Jaunt? Enter your email and we’ll create your account — no password.

Sign in or create an account

We’ll email you a sign-in link, then bring you straight back here.

Step 2: Pick your assistant

Before you start

  • Use a laptop or desktop browser — Jaunt can’t be added from the ChatGPT phone app.
  • You’ll need a paid ChatGPT plan. Availability varies by plan.

Jaunt server URL

https://api.usejaunt.com/mcp
  1. Open chatgpt.com in the same browser you’re signed in to Jaunt on.

  2. Open Settings and turn on Developer mode. It’s under Security and login — or Apps → Advanced settings on some accounts.

  3. Go to chatgpt.com/plugins and click +. A box called New Plugin opens.

  4. Type Jaunt in Name. Description is optional — “Live flights and hotels” is plenty.

  5. Leave Connection set to Server URL (not Tunnel), and paste https://api.usejaunt.com/mcp into the box underneath it.

  6. Set Authentication to OAuth. Leave Advanced OAuth settings closed — Jaunt needs nothing changed in there.

  7. Tick I understand and want to continue under the orange warning, then click Create. ChatGPT shows that warning for every custom server OpenAI hasn’t reviewed; being listed in their directory is what removes it, and we’re working on that.

  8. A Jaunt window opens — approve it.

  9. In a new chat, click + → Developer mode and pick Jaunt, or type @Jaunt.

  10. When ChatGPT asks permission to use Jaunt, choose Always allow.

Step 3: Start every chat with this

ChatGPT only uses Jaunt when you point it at Jaunt — until Jaunt is listed in its directory. These are the words that do the pointing.

Paste this at the start of a chat

The @Jaunt at the front is what selects the connector — leave it out and ChatGPT won’t use Jaunt at all. Mention @Jaunt again if a later question needs a fresh search.

Or set it once

Put this in Settings → Personalization → Custom instructions and ChatGPT carries it into every chat. It can’t switch Jaunt on for you — what it does is make ChatGPT say when Jaunt isn’t there, instead of quietly answering from memory.

Ask it like this

A deadline plus a bit of flexibility is what makes Jaunt better than a search box. Tell it when you have to be somewhere, and the window you could travel in.

Ask the same trip as one fixed date and Jaunt behaves like any other search box. Ask it with a deadline and a window and Jaunt searches every date in the window, and leans towards nonstops — a connection is what makes you miss a 10am.

Step 4: Try it

Start a new chat with Jaunt switched on and paste one of these. Tap one to copy it.

How much of your chat does Jaunt use?

Assistants read in tokens — small pieces of words — and each chat can only hold so many. Jaunt uses some of them, so here is roughly how many.

When Jaunt is switched on
About 10,000 tokens
Your assistant reads Jaunt’s list of tools, so it knows what Jaunt can do.
Each search
About 700–1,800 tokens
The flights, plan or hotels that come back. A full page of hotels is the most.

To keep your chats light

  • Switch Jaunt on only in chats about travel.
  • Ask for one trip at a time.
  • Start a new chat for a new trip.

How much this counts toward your limits depends on your assistant and your plan. Claude’s help centre suggests turning off connectors a chat doesn’t need, and starting a new chat when a long one gets close to your usage limit.

Our own estimates, measured on 14 September 2026 for Jaunt’s slimmer tool list. Your assistant may count differently.
