Guesty MCP Server

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.

Live now: 23 free read-only tools — reservations, listings, guests, calendars, financial reports, operations, reviews, and webhook reads. The full 43-tool surface (write/destructive ops + webhook management) is planned behind a paid tier; availability will be announced in the release notes.

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 registered — 23 free read-only Guesty tools live now, plus get_license_info, which reports this server's own licensing state and makes no Guesty API call. A Pro tier would add 15 gated tools: 14 write/guest-messaging operations plus get_conversations, which is read-only but is gated because it returns message content. An Enterprise IoT add-on (get_readiness_score, get_property_health, submit_checkout_photos, get_maintenance_alerts) sits above that. Paid tiers are not yet available and no release date is set.

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.

Paid tiers are not yet available. 23 free read-only tools are live now: reservations, listings, guests, calendars, financial reports, operations, reviews, and webhook reads. There is no license key to buy or enter yet, and the free tier needs none. Paid-tier license keys are recognized but refused with a message saying paid tiers are not yet available — set or omit GUESTY_MCP_LICENSE_KEY and you get the free tier either way.

Server & Licensing

This tool is available on the free tier. It is counted in the 43 registered tools but not in the "23 free read-only Guesty tools" figure, because it reports our licensing state rather than doing anything with your Guesty account: 23 Guesty tools + this one = the 24 tools the free tier can call.

Enterprise Tier

These four tools are gated to the Enterprise tier. Paid tiers are not yet available, so they cannot be unlocked today — they are documented here for completeness. Availability will be announced in the release notes.

Use Cases

• Guest Communication: guest-messaging tools draft and send replies grounded in real reservation data
• Revenue Management: Pull financial reports, analyze occupancy, optimize pricing
• Operations: Track check-ins/outs, coordinate cleaning schedules, manage availability
• Marketing: Identify low-occupancy periods, create targeted promotions
• Connected Tools: give every MCP-compatible client in your stack access to the same property data

Requirements

• Node.js 18+
• Guesty account with API access (Professional plan or higher)
• MCP-compatible AI client (Claude Code, Cursor, Windsurf, etc.)

Environment Variables
