The same listing reaches ChatGPT on the web, desktop, and mobile, Codex in the ChatGPT desktop app, the Codex IDE extension (it shows up under Codex settings → Plugins, installed and enabled), and Codex CLI through its
/plugins browser. See OpenAI Codex.Prerequisites

- Select the orgs you want ChatGPT to access.
- Click Authorize.
4
Use it
Start a new chat. Describe what you want and ChatGPT picks the plugin up on its own, or type
@ to invoke Control Plane explicitly. Ask it to “list GVCs in org <your-org>” (using one of the orgs you authorized) to confirm.The listing is fixed on the default
core toolset profile and takes no query parameter of its own. For mk8s or full, register the MCP server directly in Codex or another MCP client. See toolset profiles.For the latest directory behavior, see OpenAI’s Plugins documentation.
