Not directly, today. ChatGPT adds a remote MCP server from a URL and authenticates with OAuth or not at all. WP Visibility’s endpoint authenticates with a WordPress Application Password sent as a header, and ChatGPT’s form has nowhere to put one. This page says what that means so you do not spend an afternoon on it.
What ChatGPT’s connector needs
In ChatGPT, developer mode under Settings lets you add a connector by server URL. The server must be reachable from OpenAI’s servers over HTTPS, and the documented authentication is OAuth (client registration through client ID metadata documents) or none. There is no field for a username and password, and no custom header. Checked September 21, 2026 against OpenAI’s MCP documentation.
Why the plugin does not fit that form
The endpoint at /wp-json/wp-visibility/mcp uses ordinary WordPress REST authentication, which for a remote client means an Application Password. That is deliberate: the credential is a WordPress user with a role you chose, revocable from the user’s profile, and every call is logged under it. The plugin does not act as an OAuth provider.
The two workarounds, and why we do not recommend them
A public relay with no authentication. You could host a small service that accepts ChatGPT’s requests and forwards them to your site with the Application Password added. Registering it as a no-authentication connector means anyone who learns the relay’s URL has the assistant’s authority on your site. Do not do this.
A relay that speaks OAuth. The same relay, fronted by an OAuth server you run. This is a real piece of infrastructure to build and keep secure, for one client. If you run it, the plugin’s side is unchanged: the relay is just another client sending Basic authentication.
What to use instead
Claude Desktop and Claude Code connect today, in one config block or one command. Other clients that accept a URL plus a custom header, or that can run a local command, connect through the general doc.
If ChatGPT adds header or password authentication for connectors, or if the plugin gains an OAuth provider, this page will change. Until then, treat “ChatGPT connected to WP Visibility” claims elsewhere with care.
