Cli spawns windows temporarily for each mcp server

[grantborthwick]

Describe the bug

When I startup the github copilot cli with mcp servers, I get a terminal window briefly for every mcp server that starts. It only shows up for a split second for each, but it takes away my cursor focus so my typing doesn't go into the cli window. This is annoying, and Claude's cli doesn't do this.

Affected version

No response

Steps to reproduce the behavior

GitHub Copilot CLI 0.0.402

Expected behavior

I start the copilot cli, and it silently launches mcp servers without starting new windows.

Additional context

This is on Windows 11. I haven't tried elsewhere.
