What's Wrong?

When launching Claude Code with --resume flag, the /mcp menu opens but becomes completely unresponsive to keyboard input (arrow keys, Enter, Esc). The UI renders correctly but no input is processed.

What Should Happen?

/mcp menu should be navigable with arrow keys and respond to Enter/Esc normally.

Error Messages/Logs

nothing

Steps to Reproduce

1. Start Claude Code normally: claude
2. Exit the session
3. Resume with: claude --resume
4. Type /mcp
5. Menu opens but does not respond to any key presses

Additional Information

Actual Behavior

Menu renders but is completely frozen. No keyboard input is processed. The issue does not occur when starting a fresh session with claude (without --resume).

Workaround

Launching with TERM=xterm-256color claude --resume does not help.
Fresh claude sessions work fine — /mcp is responsive.

Additional Context

• MCP servers configured: claude.ai Gmail, Google Calendar, Google Drive (all disabled)
• Issue persists regardless of which project is resumed
• Tested with multiple projects — all exhibit the same behavior
