Manage bookings without opening your dashboard

Appointment booking MCP server for AI

Connect Calendesk to ChatGPT or Claude. Your AI checks the calendar, books clients, sends reminders, and reports revenue. Type a message - the rest happens on its own.

Book, move, or cancel - one sentence

"Schedule Anna for Friday at 2 pm." Your AI checks the entire team, spots any conflict, and confirms the appointment. No forms. No clicking around.
