This is a starter guide. A full walkthrough is coming.
Codex is OpenAI’s coding agent. You can give it KERNEL know-how with the KERNEL plugin, and KERNEL browsers as tools with the KERNEL MCP server. Use either or both.

​
Install the KERNEL plugin

The plugin adds Agent Skills for the KERNEL CLI and SDKs, so Codex knows how to create and drive browsers.
You can also find the KERNEL plugins under Plugins in the ChatGPT desktop app after adding the marketplace.

​
Connect the MCP server

The KERNEL MCP server gives Codex tools to create browsers, run Playwright code, take screenshots, and more.
codex mcp login opens your browser so you can authorize access to your KERNEL account. To use an API key instead, see MCP authentication. Start a Codex session and run /mcp to confirm the KERNEL tools are available.
