Guesty MCP Server

The first MCP (Model Context Protocol) server for Guesty property management. Connect AI agents directly to your Guesty account to manage reservations, communicate with guests, track finances, and update pricing -- all autonomously.

43 tools covering reservations, listings, guests, messaging, financials, tasks, calendars, webhooks, and pricing — plus 1 IoT tool (get_readiness_score) and 3 Enterprise-tier aggregators (get_property_health, submit_checkout_photos, get_maintenance_alerts) for property health aggregation, checkout photo intake, and portfolio maintenance alerts.

Want AI to handle your guest messages 24/7? Guesty Copilot -- AI guest management for Guesty hosts, built on this MCP server. Now in beta.
