Unclear It is not clear which connections are left out or where this list is shown.

What

MCP (Model Context Protocol) connections are Claude Code's links to outside servers that give Claude extra tools. A list that Claude Code builds from these connections now leaves out some of them before the list is made. It also works out a few extra details for each connection.

Why

Some MCP servers may no longer show up in that list.
