Hello! I'm using the new Xcode 26.3 RC and it's new MCP server:

However, I am repeatedly prompted to give access to Codex (both the new macOS app and the CLI).

And I'm seeing duplicates in the Xcode dropdown:

It's pretty blocking in my workflow as I have to keep Allowing over and over again.

The Codex app seems to drop the connection if you click on anything (away, other parts of the app). The Codex CLI should hold onto a single connection for the entire session. I recommend giving the CLI another go.

Although I do think Xcode could be a lot better here.
