Unclear It is not clear what the desktop connector feature does for a reader or where it appears.

What

MCP servers are outside programs that give Claude Code extra tools. Some of them are SDK servers, built with the Agent SDK. Claude Code's lookup for desktop connector tools now handles these servers too. It matches tools carrying either of two desktop markings and reports a "conflicting" state when a tool carries both. Before, the lookup worked by URL only.

Why

Desktop connector handling now covers SDK-type MCP servers as well.
