Scheduleonce

Scheduleonce MCP integration

Checks which slots are genuinely free, books one with the guest's details attached, creates the contact behind it, and handles cancellations and no-shows.

Three actions you can hand over today

Every action runs live through MCP. Nothing to build, nothing to maintain.

  • Book time slot

    Lyro creates a booking on a calendar for a customer. Agents schedule meetings or appointments on behalf of clients without the customer visiting a booking page.

  • Cancel booking

    Lyro removes a scheduled booking from the calendar. Agents instantly cancel customer appointments when plans change.

  • Mark booking as no-show

    Lyro records that a customer missed their scheduled appointment. Agents track attendance for follow-ups and prevent overbooking repeat customers.

How businesses use Scheduleonce + Lyro

Each card is one request a support team gets, and the Scheduleonce actions Lyro runs to close it.

  • Book the meeting inside the conversation

    Lyro pulls the slots genuinely free on a booking calendar, books the one the customer chose with their guest details attached, and creates the contact record the booking belongs to.

  • Answer what a booking says and when it is

    Lyro retrieves a booking in full - timing, location, status, and the form the customer submitted - and lists what else sits on the calendar over the range in question.

  • Handle a cancellation or a no-show cleanly

    Lyro cancels the booking with a reason attached and control over whether the cancellation email goes out, marks a completed booking as a no-show when nobody arrived, and pulls the contact behind it for follow-up.

  • Keep the team's availability honest

    Lyro reads a host's weekly schedule, working hours, and date-specific overrides, and writes back a holiday or a changed working day so the slots being offered stop being wrong.

How it works

Get started in 3 steps

Connect once, then just ask. There is no workflow builder to learn and nothing to maintain — Lyro reads the Scheduleonce actions it has and picks the ones a request needs.

  1. 01

    Connect Scheduleonce

    Authorize the Scheduleonce account your team already uses — one consent screen, no API keys, no mapping tables. Lyro can only do what you granted that account, and you can disconnect it at any time.

  2. 02

    Tell your agent what you need

    Describe the job the way you would hand it to a teammate. Lyro maps it to the Scheduleonce actions that close it and chains as many as the request needs.

  3. 03

    Watch it work

    The agent runs the actions inside the conversation the customer is already in, so nobody copies data between tabs and your team can take over at any point.

Everything else about Scheduleonce

Setup, permissions, and the limits of what Lyro can do inside Scheduleonce.

  • Thirty days per query. Get Available Time Slots takes a date range capped at 30 days and returns real-time availability computed against the booking rules and the participants' own calendars, so a request further out is checked in a second window rather than one long lookup.
