What
The interactive menu you see when you select a server in Claude Code's MCP (Model Context Protocol, a way for Claude Code to connect to external tools and data sources) server management screen used to offer three actions: Restart, Remove, and Back. The Restart option is now gone, leaving just Remove and Back.
Why
If you were used to restarting a misbehaving MCP server directly from this menu, that shortcut is no longer there.

The entry above is what we published on the day. These lines were added later, as Anthropic's own pages caught up, and they sit beside the original rather than replacing it.
Confirmed since
Anthropic's documentation has since written up Restart, on inference-hooks.
