In /mcp, Authenticate is hidden for disabled or policy-blocked servers, with an explanation if you try.

What

The server detail view in /mcp no longer offers an auth flow it cannot run, and explains why when you try.

Details
  • A guard runs before authentication: managed-policy-blocked servers report "is blocked by your organization's managed policy — it can't be authenticated or reconnected here".
  • Disabled servers report the disabled message instead of starting an auth flow.
  • "Authenticate" and "Re-authenticate" entries are suppressed for disabled, blocked and externally-disabled servers.
  • "View tools" is now offered for cached clients as well as connected ones.
