After extracting, run ./SubnetSlinger.App. For a desktop launcher and live Capture, run sudo ./install-linux.sh once — if it isn't executable yet, chmod +x install-linux.sh first.

MCP: the Deputy connects out to your own MCP tool servers on Linux, same as Windows. Running SubnetSlinger as an MCP server (so another AI app can call its tools) is in the Windows build, not the Linux build yet.

🍎 macOS ships as its own native, notarized build — a direct download like Linux, and covered by the one desktop license (Windows, macOS & Linux — buy once, no subscription). In development; coming soon.
