Build a Booking Backend Your AI App Can Actually Use

In the previous article, we connected an agent to FavCRM and discovered its 165 typed tools. Now we build something real: a booking flow that takes actual bookings - services, open slots, a confirmed booking, and a customer record that persists. No mock arrays. Every call in this walkthrough writes a row. The flow we are building create_service → get_available_slots → create_booking → confirm_booking customer record persisted The examples use the favcrm CLI because it is reproducible. An agent in Cursor or Claude makes the exact same MCP calls - it just decides the arguments itself.
