Callstay is a hotel reservation service, operated by Spotbo, Inc. (Delaware, US), that books hotel rooms online or by phone: a guest describes the stay in plain language and Callstay finds the room, arranges details with the property and completes the booking on the guest's behalf. It targets group room blocks, extended weekly or monthly stays, constrained requests (adjoining rooms, accessibility, pets, parking) and company-invoiced bookings, and publishes a public Model Context Protocol server at https://callstay.com/api/mcp for AI agents to search stays, get properties and price rooms.
