UL.la, the classifieds marketplace of Laos, now works directly inside AI assistants such as Claude. Connect your UL.la account once, and you can ask your assistant to find a car in Vientiane, post your apartment for rent, or answer a buyer, without opening the website.

What your assistant can do on UL.la

Without connecting an account, any assistant can:

  • search ads by category, place, price and details (for example "3-bedroom houses for rent in Sisattanak under 800 USD");
  • read an ad in full, with its pictures and details;
  • find similar ads;
  • read UL.la's guides on buying, selling and living in Laos.

Once you connect your account and allow it, your assistant can also:

  • post new ads for you, add pictures, change the price or the text, and take an ad offline;
  • read your conversations and send messages to sellers about their ads;
  • save ads to your favorites.

How to connect UL.la to Claude

  1. Open Claude and go to Settings → Customize → Connectors.
  2. Click + Add and choose to add a custom connector.
  3. Enter the name UL.la and the address https://api.ul.la/mcp, then add it. UL.la now appears in your connectors, with its red tag logo.

  1. Click Connect. A UL.la page opens: sign in as usual, check what Claude asks to do, untick anything you don't want, and click Allow.

Allowing Claude to use a UL.la account

That's it: you're back in Claude, and UL.la is ready to use. In the connector's settings you can also choose, tool by tool, whether Claude may use it freely, must ask you first, or may not use it at all.

Other assistants that support MCP connectors (the standard way assistants connect to services) connect with the same address.

Examples of what to ask

  • "Find me a Toyota Vios from 2018 or newer in Vientiane, under 15,000 USD."
  • "Post an ad for my Honda Click 2021, 25,000 km, 1,800 USD, in Xaysetha. Here are the photos."
  • "Lower the price of my apartment ad to 650 USD a month."
  • "Do I have new messages on UL.la? Reply to the person asking about the sofa that it's still available."
  • "Take my laptop ad offline, it's sold."

Your assistant shows you what it is about to post or send and asks before doing it.

Safe by design

  • Your password stays with you. You sign in on UL.la's own page; the assistant never sees your password.
  • You choose what it may do. Each permission (posting ads, messages, favorites) is shown and can be unticked.
  • You can disconnect at any time. Your account page lists your connected assistants; Remove cuts access immediately.
  • Sellers' phone numbers stay private. Assistants never receive anyone's phone number, WhatsApp or email. They contact sellers through UL.la messages, which show "Sent with an AI assistant".
  • Daily limits protect everyone. An assistant can post up to 5 new ads a day for you. The first ads posted through a newly connected assistant are checked by the UL.la team before they appear, usually within a day.

A few common questions

Is it free to use UL.la with an AI assistant?
Yes. Searching and posting on UL.la is free, with or without an assistant. Your AI assistant may have its own subscription.

Which AI assistants work with UL.la?
Claude works today through custom connectors: it is the assistant we have tested. Other assistants, such as Grok and OpenAI dots, can use the same address, https://api.ul.la/mcp, if they support MCP connectors. Assistants that browse websites for you, such as Meta's Muse, can also use www.ul.la directly.

Can an assistant post ads for me automatically?
Yes. Once connected with the "post, edit and close your ads" permission, ask it to post an ad and give it the details and photos. It can post up to 5 new ads a day, and your first ones are checked by UL.la before they appear.

Will the assistant see my password or my phone number?
No. You sign in on UL.la's own page, and the assistant only gets the permissions you allow. It never receives your password, and it never receives sellers' phone numbers.

How do I disconnect an assistant?
Open your account page on UL.la and click Remove next to the assistant under "Connected assistants". Its access stops immediately.

Can I search UL.la with an assistant without an account?
Yes. Searching and reading ads works without connecting an account. You only need to connect to post, message or save favorites.
