Can ChatGPT access my OwnerRez data?
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.
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 full guide shows how to build the read-only server and exactly which tools it exposes.
