 **Connected.** Fluso has a current sign-in. Tokens that are close to expiring get refreshed in the background. You don't see this happen.
 
 **Needs reauth.** The token expired and Fluso couldn't refresh it. The server probably revoked the refresh token or rotated keys. Hit the three-dot menu and click **Reconnect**.

 **Reconnect** drops the stored sign-in first, then re-opens the Add dialog with the URL filled in. Use it after a **Needs reauth**, or when you want to sign in as a different account on the same server.
 
-**Disconnect** removes the row. Fluso loses access from the next message on. This only removes the sign-in from Fluso's side. To revoke it on the server, do that from the server's own settings page. Most providers list "Fluso MCP Proxy" as an authorized application you can remove.
