HotelOne

For travellers

Book with your AI assistant

Ask ChatGPT, Claude, Grok or any AI assistant to find you a room at a HotelOne hotel. It checks live prices and hands you a booking link with everything filled in — you just confirm.

Your assistant link

https://hotelone.site/api/mcp

Free to use. No account or sign-in needed to search and get booking links.

Add it once

Paste the link into your assistant’s connector settings. It takes about a minute.

  • Claude

    1. Step 1: Open Settings → Connectors.
    2. Step 2: Choose Add custom connector, name it HotelOne and paste the link.
    3. Step 3: In a chat, switch HotelOne on from the tools menu.

  • ChatGPT

    1. Step 1: Open Settings → Apps & Connectors → Advanced and turn on Developer mode.
    2. Step 2: Choose Create, name it HotelOne, paste the link and pick No authentication.
    3. Step 3: In a chat, add HotelOne from the + menu.

  • Grok

    1. Step 1: Where Grok offers connectors or MCP servers, add a new one and paste the link.
    2. Step 2: Building with the xAI API? Add the link as a remote MCP tool — no key needed.
    3. Step 3: Then ask Grok to find or book a room.

  • Le Chat (Mistral)

    1. Step 1: Open Intelligence → Connectors.
    2. Step 2: Choose Add connector → Custom MCP connector and paste the link.
    3. Step 3: No sign-in needed. Turn it on in a chat.

  • Any other assistant

    1. Step 1: Look for Add MCP server, custom connector or remote tool.
    2. Step 2: Paste the link. If asked, choose Streamable HTTP and no sign-in.
    3. Step 3: Then just ask for a room.

  • Can’t find the setting?

    Menus move around. Search your assistant’s help for “custom connector” or “MCP”. Some plans don’t include connectors yet.

Then just ask

  • Find me a room in Santa Cruz next weekend for two and book it.
  • Is parking free at The Saltwater Inn?
  • Somewhere in Monterey for 3 nights from November 12, under $250 a night.
  • Find my booking ABC123 — the last name is Smith.

How booking works

  1. 1. It finds rooms

    Live availability and prices, straight from the hotel — not guesses.

  2. 2. You confirm

    You get a link to the hotel’s own checkout with your room and dates filled in. Check it and confirm in one tap.

  3. 3. No screen? No problem

    On a voice chat, your assistant can send your request to the hotel. The team confirms by email or phone.

Nothing is booked without your OK. Free cancellation until 3 PM the day before you arrive.

For developers

Building your own agent — on Muse, Grok, OpenAI, Anthropic or anything else? Connect over MCP or plain REST.

MCP server
https://hotelone.site/api/mcp — Streamable HTTP, stateless. One hotel only: /api/mcp/hotels/{hotel id}
REST API
The same operations with an OpenAPI 3.1 description — import it as a GPT Action or any tool-calling setup.
For models
llms.txt, llms-full.txt and an agent card.
Confirmed bookings
Search, booking links and requests need no key. To book directly (paid at the hotel), ask the hotel for an API key and send it as Authorization: Bearer.

Run a hotel? Give guests your own assistant link — it’s in your console under AI assistants.
