+**Viewing attached servers with `/mcp list`** (v1.0.69+): Use `/mcp list` to see which MCP servers are currently attached to your session and their status. Unlike `/mcp show` (which shows all configured servers), `/mcp list` focuses on what's active right now and can run **while the agent is working** — useful for checking server status mid-turn without interrupting the agent:
+
+```
+/mcp list              # show servers attached to this session
+```
+
+You can also open the `/mcp` manager while the agent is working to toggle servers on or off mid-turn. Add, edit, delete, and re-auth actions wait until the turn finishes, but enabling or disabling a server takes effect immediately.
+
 **Toggling servers on and off** (v1.0.66+): From the `/mcp` list view, you can **enable or disable individual MCP servers** without editing your config file. Select a server in the list and toggle it — disabled servers won't start in future sessions and their tools won't be available to agents. This is useful for temporarily disabling a server that's causing slowdowns or errors without removing it from your configuration entirely.
