millio for AI assistants

millio runs a public MCP server. An assistant that supports MCP connectors can search the places listed on millio, read their menus, prices and staff languages, explain how booking works, and hand you a booking link with your service and preferred times already filled in. The assistant cannot book or pay for you — you send the request yourself on millio.co.

How a booking happens

  1. 01The assistant finds and reads a place for you (search_salons, get_salon).
  2. 02It builds a booking link with start_booking and shows it to you.
  3. 03You open the link on millio.co, sign in with Google, LINE or email, and send the request with up to three times.
  4. 04The place confirms one of your times. Only then do you pay online, with PayPal or a card. Nothing is booked or paid inside the assistant.

Your data

The MCP server does not ask for your name, email, phone number or any account, and it does not save what your assistant sends. Tool calls carry only search filters (type, area or place name), a place id, a service id, up to three times and a language, and the answers come from the same public listings anyone can see on millio.co.

Links from the server carry two tags so we can count visits that came through an assistant: utm_source (the assistant app's software name, for example claude-ai) and utm_medium=mcp. Nothing about you is in them.

When you open a link and book on millio.co, millio's privacy policy applies to the details you give there.
