You connect Guesty to your AI assistant through MCP, and Guesty now makes that official: it ships a first-party MCP server, in early beta as of July 2026. Once connected, Claude, the Gemini CLI, or ChatGPT (via the hosted endpoint) can read your listings, reservations, calendar, and guests and answer questions in plain English.
The setup paths
The official server is read-only during beta, so the assistant can look but not change anything. The three steps:
- Create an OAuth application. In Guesty, open Integrations, then OAuth applications, create a new application, and copy the client ID and secret. Open API access is self-serve on plans that include it.
- Connect the server. Locally, run npx -y @guestyorg/sdk mcp with your credentials and register it in Claude or the Gemini CLI; for ChatGPT, use the hosted endpoint https://mcp.guesty.com/v1. Prefer to control the exact tool surface? Build the small read-only server from our guide instead.
- Ask in plain English. Point Claude, Gemini, or ChatGPT at the server and ask things like "what checks out tomorrow?" or "which listings are open this weekend?"
The hosted API route
For a tool that has to keep running unattended, there is also a hosted path: the RapidEye API exposes Guesty as a hosted connector, so the auth model and its limits are handled centrally and your code calls one consistent surface. The catalogue is machine-readable, so an AI agent can discover it mid-task and surface the next step itself.
