wtf is tailscale-mullvad-toggle?

This project is a small command line tool and macOS menu bar app that makes it easy to turn a Mullvad VPN exit node on or off inside Tailscale, a private networking service. Normally switching exit nodes means going through several manual steps, and this tool turns that into a single command or a click in the menu bar. The tool does not run its own server or require a cloud account. It works entirely by talking to your local Tailscale installation and reading the list of available exit nodes. When you run a command like turning the exit node on for a specific country or city, it looks at your Tailscale status, finds the Mullvad exit nodes that are currently online, picks the best match for your preference, and applies that setting using Tailscale's own command line tool. A companion feature checks whether your Tailscale network actually has the Mullvad add on enabled yet. If it is not, the tool points you to the right setup page instead of failing silently. There is also a way to verify your public network exit point using Mullvad's own connection checker. To use it, you need Tailscale already installed and signed in, plus a Tailscale network with the Mullvad VPN add on turned on. The menu bar interface additionally requires a macOS tool called SwiftBar. Installation is a single shell command that downloads and sets up the tool, after which you can run commands such as listing available countries, turning the exit node on for a specific country, or checking its current status. The README does not state a specific license for the project. It explicitly avoids collecting or transmitting any of your data beyond what is needed to reach Tailscale and Mullvad's own services.
