What's Wrong?

Bug Description

On Linux Mint, interactive claude hangs indefinitely at startup. The process does
NOT exit — it stays alive and unresponsive until manually killed (Ctrl+C). The TUI never renders. claude doctor reports everything OK, including
active Max subscription auth.

The debug log shows startup proceeds normally up to fetching MCP servers, then goes
completely silent for ~29 seconds until the process is killed by timeout. The hang
is immediately after the "[claudeai-mcp] Fetched 3 servers" line.

What Should Happen?

Environment

• OS: Linux Mint (x64)
• Claude Code version: 2.1.156 (native installer, ~/.local/bin/claude)
• Platform reported by doctor: linux-x64

• Subscription: Max (doctor shows: ✓ claude.ai OAuth token present,

✓ claude.ai subscriber auth active, ✓ Organization UUID resolved)

• 3 remote MCP connectors enabled on the account: Google Calendar, Gmail, Google Drive
• Working directory IS a git repository

What I've Tried (none fixed it)

• Reinstalled via native installer (fixed an earlier npm bug that symlinked to

claude.exe — a Windows binary — on Linux; worth a separate report)

• Verified network: curl -I https://api.anthropic.com/v1/mcp_servers returns 405

instantly (server reachable, not a network hang)

• claude --strict-mcp-config --mcp-config '{"mcpServers":{}}' → still hangs at the

same point

• CLAUDE_CODE_DISABLE_NONESSENTIAL_TRAFFIC=1 claude → still hangs
• Tried TERM=xterm, different terminal → still hangs
• claude doctor is fully green, no ✗

Error Messages/Logs

## Debug Log (~/.claude/debug/latest)
2026-05-29T12:39:09.331Z [DEBUG] [claudeai-mcp] Fetched 3 servers
<-- ~29 seconds of complete silence here, process hangs -->
2026-05-29T12:39:38.869Z [DEBUG] Broken symlink or missing file encountered for 
    settings.json at path: /etc/claude-code/managed-settings.json
(the 12:39:38 lines only appear when `timeout` kills the process)

Full startup completes (CA certs, MCP config load, atomic write of .claude.json, 
"Fetched 3 servers") then hangs with no further log output until killed.

Steps to Reproduce

1. cd into a git repository
2. Run claude
3. Terminal hangs indefinitely, no TUI, no output, must Ctrl+C

Is this a regression?
