}🔴book_meeting(meeting_type, start, name, email, notes, ...)
Book a call with Jan Linketscher on behalf of your user. The start must be a slot returned by get_availability. If your client supports elicitation (form mode, MCP 2026-07-28), the server itself asks the user to confirm time, name and email – name and email are then prefilled from your arguments and can be corrected by the user. Otherwise: show the user meeting type, date and time (with time zone), name and email, get their explicit approval, then pass name, email and confirmed: true. Use the user's real name and email; never invent them. Cal.com sends the confirmation with a calendar invite and links to reschedule or cancel to that email address.
