The mcp-tailscale server provides read-only monitoring and inspection of your Tailscale network (tailnet) through the following tools:
List all devices (tailscale_list_devices): Retrieve all devices in your tailnet with details like name, hostname, IP addresses, OS, and connection status; optionally filter which fields to return
Get a specific device (tailscale_get_device): Look up detailed information about a single device by its numeric ID or name
List online devices (tailscale_list_online_devices): View only devices currently connected to the Tailscale control plane
List offline devices (tailscale_list_offline_devices): View only devices that are currently disconnected or offline
Check for updates (tailscale_check_updates): Identify which devices have Tailscale client updates available
Get a network summary (tailscale_device_summary): Get an overview of your tailnet broken down by OS type, online/offline status, and update availability
Allows managing a Tailscale network (tailnet) by listing devices, checking online/offline status, monitoring connection health, viewing available client updates, and retrieving network summary statistics.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-tailscale Which of my devices are currently online?"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
