Research direction

Start by comparing the working implementation in the linked fork, based on Codex 0.144.6, and read FastMCP's official progress-reporting behavior. Trace MCP client handling in the Codex CLI/TUI and App, then verify that progress/report updates are surfaced dynamically in both interfaces.

Description

app CLI enhancement mcp TUI

What variant of Codex are you using?

CLI

What feature would you like to see?

I would like to request a feature for the Codex TUI(CLI) and the Codex App feature,
Currently, when Codex invokes MCP tool that takes a long time to execute, the UI provides minial feedback and less information.
We should impletmet support standard MCP progress feature on client-side(Codex App/cli).
For implement reference, highly recommend looking into the FastMCP official report progress function to update the UI dynamically (e.g., displaying a percentage loader or step-by-step progress bar).

Additional information

I have created a working implementation of this feature based on version 0.144.6
