Codex?

Yes! Because the Codex CLI supports the Model Context Protocol (MCP) and lifecycle hooks, it actually worksperfectly out of the box.

In fact, your comment just inspired me to push a quick update a few minutes ago: if you pull the latest version, running engrim setup will now auto-detect your ~/.codex folder and completely wire up the MCP server and hooks (SessionStart, UserPromptSubmit, etc.) natively. Give it a try!

Thanks for being responsive. I'll try it.
