What probably matters to youSection of the release

Unclear It is not stated what you would notice once the waiting-server list comes back empty under mcpAutoDiscovered.

What

MCP servers are separate programs that give Claude extra tools. Plugins are add-on packages that extend Claude Code. Two things changed:

  • An MCP server can now be shown with the reason "Removed from this session by a plugin", meaning a plugin took it out of the current session.
  • The list of MCP servers waiting to be added now comes back empty when the mcpAutoDiscovered setting is set, in addition to the one condition that emptied it before.
Why

Plugins now have a way to take MCP servers out of a session, and when you see that reason you know a plugin did it rather than you or your settings.
