Claude Code 2.1.136: MCP Auth Fixes, Auto Mode Rules, UI Polish

Claude Code 2.1.136 fixes critical MCP OAuth token loss during concurrent refreshes, stops servers from disappearing after /clear, and ships 50+ UI and terminal fixes across all platforms.

TL;DR

MCP OAuth tokens no longer lost during concurrent refreshes — daily re-auth is gone
MCP servers stop disappearing after /clear command across all IDEs
New hard_deny auto mode classifier rules for unconditional blocking
50+ UI, terminal, and plugin fixes for dialogs, file pickers, and rendering

New

CLAUDE_CODE_ENABLE_FEEDBACK_SURVEY_FOR_OTEL — re-enable session quality survey for enterprises using OpenTelemetry response capture
settings.autoMode.hard_deny — auto mode classifier rules that block unconditionally, ignoring user intent or allow exceptions
