What you can do with the app

Our app works inside ChatGPT, Claude and other artificial intelligence assistants that support MCP, the open standard for connecting assistants to services. You ask the assistant as usual and, when needed, it looks up our data without you leaving the conversation:

• Search cars (buscar_coches): listings of cars for sale in Germany and the rest of Europe that we have already reviewed, with the final price delivered in Spain (car, transport, taxes and registration) and a link to each one on autojung.es. You can filter by make, model, year, mileage, fuel, gearbox and price. They are cars reviewed in recent days, not live listings: if none match, it tells you so and you can ask us to find one for you.
• Estimate what it costs to import a car (calcular_coste): what a car bought in another European country would cost in Spain, with transport, registration tax based on its CO₂ and the Spanish tax tables, VAT when it applies, the inspection (ITV), the traffic office fee and the plates. It uses the same calculation as our website.
• AUTO JUNG information (info_autojung): how we work, timescales, contact details, opening hours and our guides.
• Ask for a quote (pedir_presupuesto): sends your request to our team. First, the assistant shows you the data it will send and asks you to confirm. We reply within 24 working hours, Monday to Friday, 9:00 to 19:00 (Spanish time).

The app is free and needs no account. It does not charge for or sell anything: we always give you the closed price in writing before you buy.

How to add it in Claude

If AUTO JUNG already appears in Claude's connector directory, find it there and connect it. If not, add it as a custom connector (any plan works, including the free one):

1. On claude.ai or in the desktop app, open Customize › Connectors, press + and choose Add custom connector.
2. Name: AUTO JUNG. URL: https://autojung.es/ia/mcp, exactly as written, with no trailing slash. No sign-in is needed.
3. In a chat, press + › Connectors, turn on AUTO JUNG and ask away. Claude may ask for your permission before using a tool; before sending a quote request it always asks.

This link opens Claude's form already filled in (you only need to confirm it):

Add to Claude

On Team and Enterprise plans, connectors are added by an owner of the organisation. On mobile, the app appears if you added it before on the web or on desktop.

How to add it in ChatGPT

If AUTO JUNG already appears in the ChatGPT directory, find it there and add it. If not, it can be added as your own server, depending on your ChatGPT plan (some plans only allow looking things up, without sending requests):

1. Go to chatgpt.com/plugins, press + and choose Add custom MCP server.
2. Name: AUTO JUNG. URL: https://autojung.es/ia/mcp. Authentication: none. Accept the notice, create it as a plugin and install it.
3. In a new chat, type @, choose AUTO JUNG and ask away.

Other assistants

Any assistant or program that supports MCP can use it with the same address, https://autojung.es/ia/mcp, with no key and no sign-in.

Examples to get started

• “Find automatic cars from 2020 or newer under €45,000 delivered in Spain.”
• “Show me automatic plug-in hybrid cars under €45,000 I could import to Spain.”
• “How much would it cost to bring to Madrid a €31,000 diesel SUV from Germany, first registered in June 2023, with 135 g/km of CO₂?”
• “How does importing a car with AUTO JUNG work? Do I need to travel to Girona?”
• “Ask AUTO JUNG to find me a Volvo XC60 T8. My name is… and my email is…”

If the assistant does not use the app, mention it in your question (“With AUTO JUNG, …”) or check that it is turned on in that chat.

What data reaches us

• We never receive the conversation: only what the assistant sends us with each query.
• For searches and estimates, the details of the car and, if you give it, the province of delivery (never your address). We do not keep them: we only count how many times each tool is used and from which assistant.
• If you ask for a quote: your name, your phone number or your email, the car you are looking for and, if you wish, a comment, the link to the listing, your budget and how you would like us to reply. Nothing is sent without your confirmation; if you give us your email, you get a confirmation.
• We do not keep the IP address of these queries.
• The assistant is a service run by another company (for example, OpenAI or Anthropic), which handles your conversation under its own terms and privacy policy.

Full details in section 3.11 of our Privacy policy (in Spanish).

Prices and terms

The prices and costs the app gives are estimates. We always give you the closed price in writing before you buy, and asking for it commits you to nothing. The cost estimate does not include our fee (it goes into that closed price) and does not cover the Canary Islands, Ceuta or Melilla. Our Terms and conditions (in Spanish) apply.

Technical details

• Server address: https://autojung.es/ia/mcp (Streamable HTTP, stateless, no authentication).
• MCP protocol versions: 2026-07-28 and 2025-11-25 (and earlier).
• Four tools: three read-only and one that sends data (pedir_presupuesto), marked so that the assistant asks for confirmation.
• Search results can be shown as car cards (MCP Apps) in the assistants that support it.
• It has daily usage limits to prevent abuse: if they are reached, the search answers with results already calculated and says so.
