Claude Code can now show a warning notification for 20 seconds when MCP servers are disabled in a session running in REPL mode. The warning is behind an internal check.\n\n**Why**\n\nIf your MCP tools seem to be missing in a REPL-mode session, this warning tells you they are switched off there rather than broken.\n\n- Area: REPL Mode\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
