MCP (Model Context Protocol) servers are add-ons that give Claude extra tools. Claude Code fetches a list of official MCP server web addresses. It used to pick between two ways of fetching that list based on a remote switch. It now always uses the newer way, and the older way has been removed.
If the fetch fails, Claude Code now records zero addresses. It no longer keeps a partial list.
The newer way of fetching the list is now used for everyone. When the fetch fails, nothing from it is used.
