Yes, on your terms and read-only. You create an OwnerRez Personal Access Token, run a small MCP server (or expose the v2 API as a custom GPT Action), and ChatGPT only sees the data your tools choose to expose, such as bookings, properties, and payments. It cannot change anything unless you deliberately add write tools.
Your options today
ChatGPT added Model Context Protocol support in September 2025 and connects to remote MCP servers over HTTP, so the path is to host the OwnerRez MCP server (or wire the v2 API into a custom GPT). You decide which endpoints the server wraps, which is what keeps access scoped: if the server only exposes read tools, that's all ChatGPT can ever do.
Your account email and token live in the server's environment, not in the chat, and a read-only server never sends a write request to OwnerRez. If you ever want to cut access, delete the Personal Access Token under Settings and the connection goes dark instantly.
The hosted API route
One more option if the manual export loop above gets old: the RapidEye API exposes OwnerRez as a hosted connector, so a custom tool or agent reads the data through one consistent surface instead of you ferrying CSVs. The catalogue is machine-readable, so an agent can discover it without help.
