For AI assistants

Ask an AI when your MOT is due, no app required.

Motorbook has no accounts, so its MOT and tax data was already free to look up by registration number. Now it's also available to AI assistants directly, an MCP server for Claude, and an OpenAPI schema for a ChatGPT Custom GPT, so something like Claude or ChatGPT can answer instead of sending you off to look it up yourself.

https://motorbook.uk/mcp

Add it in Claude

  1. Open Settings → Connectors → Add custom connector in Claude.
  2. Paste in https://motorbook.uk/mcp as the server URL. There's no sign-in step, because there's nothing to sign in to.
  3. Ask something like “what's the MOT and tax status on AB12 CDE?” or “find fuel stations near me”, and Claude will call it directly.

Add it to ChatGPT

As a Custom GPT action, using the same data over a plain REST API.

  1. In ChatGPT, go to My GPTs → Create (or edit an existing GPT), then open the Configure tab.
  2. Scroll to Actions and choose Create new action.
  3. Under Import from URL, paste in https://motorbook.uk/openapi.json.
  4. Set Authentication to None. There's nothing to authenticate, because there's no account.
  5. Save, then ask your GPT the same kind of question, it'll call lookupVehicle, findFuelPrices, findEvCharging or findGarages as needed.

What it can answer.

Four read-only capabilities, all backed by the same official DVLA and DVSA data the app uses. Same four, on both integrations, just named to each platform's convention.

lookup_vehicle · lookupVehicle

MOT and tax status, due dates, and MOT history for a UK registration number.

find_fuel_prices · findFuelPrices

Nearby petrol and diesel prices by brand and forecourt.

find_ev_charging · findEvCharging

Nearby EV charging points within about 25km.

find_garages · findGarages

Nearby garages, mechanics and tyre shops.

Claude uses https://motorbook.uk/mcp (stateless Streamable HTTP over JSON-RPC). ChatGPT uses the OpenAPI schema at https://motorbook.uk/openapi.json (plain REST, the same endpoints the app calls). No session, no API key, and nothing you ask is stored, because Motorbook doesn't store anything tied to who's asking.

Why the app still matters

An AI assistant can answer a question the moment you ask it, but it won't nudge you a month before your MOT is due if you never ask. That's what the app is for: it watches your dates for you and reminds you before they matter, keeps a Wallet pass and home screen widget, and holds your service history and photos in one place across as many vehicles as you own. Asking Claude or ChatGPT is the quick lookup. The app is the thing that remembers so you don't have to.

Want it to remind you automatically?

Motorbook reads your car's MOT and tax straight from official UK records, then reminds you in good time. Two cars free, forever.
