Guesty MCP Server

The first MCP (Model Context Protocol) server for Guesty property management. Connect any MCP-compatible AI client (Claude, ChatGPT, Copilot, Cline) to your Guesty account — manage reservations, communicate with guests, track finances, update pricing.

Just shipped v0.9.5: 23 free read-only tools — reservations, listings, guests, calendars, financial reports, operations, reviews, and webhook reads — live now. The full 43-tool surface (write/destructive ops + webhook management) ships behind a paid tier in v1.0 next week.

Why MCP: Guesty is one of the larger PMS platforms in the short-term-rental space and no MCP integration existed. Every major PMS will need one — we built the first.

Built in production on 10 of our own short-term rentals. Node.js + MCP SDK + Express, MIT licensed. Things we learned: Guesty's /reservations endpoint only returns future data (we use the calendar endpoint for historical), and the SSE transport doesn't run on Vercel serverless (expected). The first and only MCP server for Guesty — 23 free read-only tools live now.

Full tool surface: 43 tools total — 23 free read-only tools live now; the full 39-tool Pro tier (adds 16 write/guest-messaging tools) and a 4-tool Enterprise IoT add-on (get_readiness_score, get_property_health, submit_checkout_photos, get_maintenance_alerts) unlock at v1.0.

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.
