You connect OwnerRez to your AI assistant with a small MCP server: a local program that wraps the OwnerRez v2 API and exposes it as tools. Once connected, Claude, the Gemini CLI, or ChatGPT (via a hosted connector) can read your bookings, properties, guests, and payments and answer questions in plain English.
The setup paths
It's free, takes about 10 minutes, and is read-only by default, so the assistant can look but not change anything. The three steps are the same whichever assistant you use:
- Create a Personal Access Token. In OwnerRez, open Settings and create a new Personal Access Token. The v2 API authenticates with Basic Auth, your account email plus the token, so there's no OAuth flow and no partner approval.
- Run the MCP server. A small Node.js file wraps the API and exposes read-only tools for bookings, properties, guests, and payments.
- Ask in plain English. Point Claude, Gemini, or ChatGPT at the server and ask things like "who checks in on Friday?" or "what payments landed this week?"
The hosted API route
For a tool that has to keep running unattended, you call the OwnerRez API directly rather than going through an assistant. Our OwnerRez API guide covers the auth model and the limits to design around.
