Claude Code now shows a persistent notification when an MCP server's automatic reconnection attempts run out

What

Claude Code connects to MCP servers (external tool providers that plug into Claude Code) and tries to reconnect automatically if a server disconnects. If those automatic reconnection attempts run out without success, a persistent notification now appears telling you to reconnect manually by running /mcp. The notification clears on its own once the server successfully connects again.

Why

Previously a server could sit disconnected without a clear signal that automatic retries had given up. This notification makes it obvious when manual action is needed, and points directly at /mcp to fix it.
