Unclear It is unclear whether this log line ever reached you on screen or only went to the debug log.

What

MCP servers are outside programs that give Claude Code extra tools. When one fails to connect, Claude Code logs the error text the server printed. It now does this only if Claude Code has not yet started cleaning up to exit. Before, it always logged it.

Why

This cuts out misleading MCP error lines when you end a session while servers are still connecting.
