driver_session
[Tauri Apps Only] Start/stop automation session to connect to a RUNNING Tauri app. Supports multiple concurrent app connections - each app runs on a unique port. The most recently connected app becomes the "default" app used when no appIdentifier is specified. Use action "status" to check connection state: returns single app format when 1 app connected, or array format with "isDefault" indicator when multiple apps connected. Action "stop" without appIdentifier stops ALL sessions; with appIdentifier stops only that app. The identifier field (e.g., "com.example.myapp") uniquely identifies each app. REQUIRED before using other webview_* or ipc_* tools. Connects via WebSocket to the MCP Bridge plugin in the Tauri app. For browser automation, use Chrome DevTools MCP instead. For Electron apps, this tool will NOT work.
