What is the Guesty MCP server?

MCP server for Guesty property management — 43 production tools + 7 addressable resource templates covering reservations, guests, messaging, pricing, revenue, tasks, webhooks, and IoT/property-health Enterprise tier. Exposed over MCP by the guesty mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

What it actually does

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.

Its toolset

Everything the assistant can do here goes through one of these:

  • Messaging — The Messaging tool exposed by this server
  • Operations — The Operations tool exposed by this server

Adding it to your client

Installation goes through your MCP client rather than a global install: point it at guesty-mcp-server on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Configuration

You will need 4 environment variables: GUESTY_CLIENT_ID, GUESTY_CLIENT_SECRET, GUESTY_MCP_LICENSE_KEY, IOT_WEBHOOK_SECRET. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

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

When to reach for it

Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Guesty's toolset — Messaging, Operations — is a fair guide to whether it matches your workflow. It is maintained by dljrealty; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Guesty's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the guesty mcp server does with a few real requests.

Frequently asked questions

It connects Guesty to MCP-compatible AI assistants such as Claude and Cursor, exposing 2 tools (Messaging, Operations) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Guesty directly.
