Gemini CLI Tailscale MCP by usefulapi tailscale_get_device
How to: Gemini CLI Tailscale MCP by usefulapi tailscale_get_device
Add Tailscale MCP by usefulapi to Gemini CLI
-
01
Open ~/.gemini/settings.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"tailscale": {
"httpUrl": "https://tailscale.usefulapi.io/mcp"
}
}
}-
02
Save the file and restart Gemini CLI.
-
03
Ask for something tailscale_get_device does. Gemini CLI lists the server's tools on connect and calls tailscale_get_device itself — you do not invoke it by name.
-
04
If nothing happens, check the server is running and that Tailscale MCP by usefulapi's identifier in your config matches the one above exactly.
Gemini expands $VAR and ${VAR} inside env values, so a secret can live in your shell rather than this file. Gemini CLI docs
Same tool, other clients
This list was read from the server itself, by connecting to it and calling tools/list on 14 November 2026. It is what
the server actually exposes, not what its listing claims.
Mutating and Read-only are read off each tool's name, not its schema — a hint, not a guarantee. The registry stores tool names only; connect the server for its live schemas.
