Unclear It's unclear what the xaa command actually does or when it's exposed to users, since only the reference to the login module was found.

What

A new CLI command function is wired to a command named xaa, and it references a module for IDP (identity provider) login related to MCP (Model Context Protocol).

Why

This points to a new or upcoming way to log in to an MCP server through an identity provider, though the finding doesn't show what the command does when run.
