Unclear It is not clear whether the code that revoked MCP sign-in tokens was removed or only appears to have moved.

What

Claude Code can serve tools to a remote caller. That remote serving can now wait on a long-running task from an MCP server (an outside program that gives Claude Code tools) by repeatedly checking its status. It answers when the task is gone or not working. This sits behind a remote switch.

Why

This is part of how remote tool serving works and has no direct effect on everyday use.
