Acts, when you ask

These change something in SimplyBook.me. The model is told to use them only when you ask for exactly that, and each one is granted by name: per team on a shared connection, by the owner on a personal one.

• simplybook_create_bookingBooks an appointment in SimplyBook.me for a client with a provider and service at a start time (company time zone, from simplybook_availability).
• simplybook_cancel_bookingCancels a SimplyBook.me booking (its status becomes canceled and the slot is freed); it cannot be un-cancelled…
• simplybook_approve_bookingApproves a SimplyBook.me booking that is waiting for approval (Approve booking feature), confirming it; SimplyBook.me may notify the client.
• simplybook_decline_bookingDeclines a SimplyBook.me booking that is waiting for approval, so it does not go ahead; SimplyBook.me may notify the client.

• simplybook_add_calendar_noteAdds a note to the SimplyBook.me calendar for a time span, for a provider, a service or everyone (mode), and can block that time so nobody books it.
• simplybook_delete_calendar_notePermanently deletes a SimplyBook.me calendar note; any time it blocked opens for booking again.

• simplybook_send_payment_linkSends the client of a SimplyBook.me order or invoice a link to pay it online, by email or SMS (someone outside the company; SMS may use SMS credits).

Connect it

First connect SimplyBook.me on Dashboard → Connections, then add Memtro to your client once. The SimplyBook.me tools appear alongside the tools of everything else you have connected; nothing is configured per connector.

Who may use it

The key identifies the person, and the server offers that person the tools they may use everywhere else in Memtro. A shared SimplyBook.me connection is used by the teams an administrator granted it to, tool by tool, on the Permissions page; a personal connection is used by its owner alone, and its tools that act stay off until the owner allows them. See Teams and permissions and Connectors.

Ask it like this

• › What is booked tomorrow?
• › When is the next free massage slot?
• › Which invoices are still outstanding this month?
• › Which bookings were cancelled last week?
• › Add a calendar note blocking Friday afternoon for staff training.

Questions

Is this an official SimplyBook.me MCP server?

No. It is Memtro's MCP server with Memtro's SimplyBook.me connector behind it: the connector reads SimplyBook.me through its API with the credentials you connect on Dashboard → Connections, and SimplyBook.me publishes nothing here. The same endpoint carries every other system you connect and Memtro's memory tools.

What does it cost?

Nothing on top of Memtro. One price per organisation by its number of users, from $50 a month for up to 10 users after a 7-day free trial, with every connector, the MCP server, jobs and memory included. You bring your own model keys.

Can it change anything in SimplyBook.me?

Only when you ask, and only what it has been granted: book an appointment for a client (the client is notified); cancel a booking; approve a booking waiting for approval; decline a booking waiting for approval; set a booking's comment; create a client; update a client's name or contact details; delete a client; block or unblock a client from logging in; add a calendar note or time block; delete a calendar note; mark an invoice as paid; send a client a payment link by email or SMS. Every other tool reads, searches or lists. An administrator grants each acting tool by name per team, and a personal connection acts only after its owner allows it.

Which clients work?

Any MCP client that speaks Streamable HTTP: Claude Code, Cursor, Claude Desktop, OpenCode, Codex, Zed, Windsurf, Cline and the Anthropic and OpenAI SDKs. There is no local process to run; the server is remote and authenticated with your key.
