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

Start Claude Code normally: claude
Exit the session
Resume with: claude --resume
Type /mcp
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

Version: 2.1.119 (Claude Code)
System: Win10 - Native Client
Client: PowerShell 7.5.4 / Windows Terminal

Can confirm this on native Win 10 as well, not running on WSL2. /mcp and /resume are hard locked after messing with a few mcp settings but _even after reverting them_. Creating a brand new conversation suddenly it's okay again. This is a very frustrating one.

Also: Disabled additional MCP servers with ENABLE_CLAUDEAI_MCP_SERVERS=false in env settings, then set up a small toy mcp server and verified working in a new session. Upon resuming the old session with those same verified working settings then in place, /rewind and /mcp both still hard lock. It's some kind of session and/or settings poison.

Process gets stuck/frozen but at 0% CPU usage, ctrl+c won't kill it, have to taskkill.

Confirming /rewind and /mcp locking on WSL2 Windows 11. This is a regression.

I'm seeing this too on Debian: Debian 6.12.74-2 (2026-03-08) aarch64 GNU/Linux with Claude Code 2.1.119. Regular usage of Claude Code seems to work fine but the /mcp command freezes the TUI in an unrecoverable way.

Pretty minimal config on this VM, here's the MCP section, lemme know if more of the file would be useful:

 "projects": {
    "/home/claude": {
      "allowedTools": [],
      "mcpContextUris": [],
      "mcpServers": {
        "playwright": {
          "type": "stdio",
          "command": "npx",
          "args": [
            "@playwright/mcp@latest"
          ],
          "env": {}
        },
        "tidewave": {
          "type": "http",
          "url": "http://127.0.0.1:/tidewave/mcp"
        }
      },

❯ claude mcp list
playwright: npx @playwright/mcp@latest - ✓ Connected
tidewave: http://127.0.0.1:/tidewave/mcp (HTTP) - ✗ Failed to connect

Fix should be in v2.1.120.
