Workaround

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

Preflight Checklist

  • I have searched existing issues and this hasn't been reported yet
  • This is a single bug report (please file separate reports for different bugs)
  • I am using the latest version of Claude Code

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

Claude Model

Sonnet (default)

Is this a regression?

I don't know

Last Working Version

No response

Claude Code Version

2.1.119 (Claude Code)

Platform

Anthropic API

Operating System

Windows

Terminal/Shell

WSL (Windows Subsystem for Linux)

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

extent analysis

TL;DR

The issue with the /mcp menu being unresponsive to keyboard input when resuming a Claude Code session with the --resume flag may be related to the session resume functionality or terminal compatibility.

Guidance

  • Verify that the issue is specific to resuming sessions by testing with different projects and sessions to confirm the pattern.
  • Check if there are any known issues or updates related to the --resume flag in the Claude Code documentation or release notes.
  • Test the --resume functionality in a different terminal or shell environment to see if the issue is specific to WSL (Windows Subsystem for Linux).
  • Consider reaching out to the Claude Code support or community to report the issue and gather more information about potential workarounds or fixes.

Notes

The provided workaround using TERM=xterm-256color claude --resume does not resolve the issue, suggesting that the problem may be more complex. The fact that fresh sessions work fine and the issue only occurs when resuming a session points towards a potential issue with session management or compatibility.

Recommendation

Apply workaround: None currently available; further investigation and reporting to the Claude Code support or community are recommended to find a suitable solution.
