The MCP connector is the simpler route: one URL and a sign-in, and ChatGPT sees all the Train Badger tools. An Action uses the OpenAPI description with a personal API key, which suits custom GPTs.

Does ChatGPT need a paid plan?

Adding custom MCP connectors depends on your ChatGPT plan and settings, which OpenAI controls. If your plan does not offer connectors, the API-key route with Actions is the alternative.

Yes. The Train Badger API is in beta, open to every account, with no subscription tier.

Does my agent file the claim without asking me?

No. Your agent prepares the claim on the train operator's own website and shows it to you. It files only when you tell it to, then marks the journey as claimed so it is never claimed twice.

What does it need from my ticket?

Only the journey facts: stations, date, departure time, ticket type and, optionally, the fare. Train Badger never needs your booking reference, ticket number or name.

How long do I have to claim?

Delay Repay claims are due 28 days from the day of travel for nearly all operators. Train Badger can look up any journey from the last 35 days.

Which train companies are covered?

All National Rail operators that run Delay Repay, including season and flexi tickets.

Delay Repay with AI

Claim Delay Repay with ChatGPT

Connect ChatGPT to Train Badger once, then ask it in plain English whether your train was late and what you can claim.

Yes, ChatGPT can claim Delay Repay for you once it is connected to Train Badger. Add Train Badger's MCP server as a connector, sign in once, and ChatGPT can check whether a UK train was late, register your upcoming trains, and prepare the operator's claim form for you to approve before anything is filed.

What your agent does for you

Registers your trains from your ticket confirmation emails or your calendar, each leg before you travel.
Finds what you’re owed. Train Badger checks every registered journey against live rail data and tells your agent which ones qualify, with the operator’s claim link and, where a fare is known, the amount.
Prepares the claim and shows it to you. It fills in the operator’s own claim form, files only when you say so, and marks it filed so it is never claimed twice.
Answers “was my train late?” for any journey in the last 35 days.

How to connect ChatGPT

Create a free Train Badger account and verify your email.
In ChatGPT, add an MCP connector with the URL https://api.trainbadger.app/mcp. ChatGPT opens a Train Badger page: sign in if asked, then approve.
Give ChatGPT this instruction:

“Connect to Train Badger's MCP server at https://api.trainbadger.app/mcp — sign me in when it asks. Each morning, pre-register the trains I'll take today. Whenever a journey becomes claimable, prepare the Delay Repay claim and show it to me before you file it.”

Prefer Actions? ChatGPT can also use the OpenAPI description at https://trainbadger.app/api-docs/openapi.json with a personal API key from your account.

Try asking

“Was my 08:15 from Paddington to Reading last Tuesday late, and can I claim?”
“Register tomorrow's 07:32 Berkhamsted to Euston for me — off-peak return, £24.60.”
“Which of my journeys can I claim Delay Repay for? Prepare the claims and show me before you file anything.”
