Google CLI: Google from the command line

Google in the terminal

Sign in with Google and pick the permissions. Google ships no MCP server, so the Gmail, Calendar and Drive tools a workspace gets are ours, under the same permissions as every other tool. What each AI or terminal may do with them is set level by level, on its own page.

Install the CLI, then connect Google

Google is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.

# Install the CLI
$ curl -sSL https://gbrainio.terminalwire.sh | bash

# Set the terminal up and connect it
$ gbrainio terminal connect

# What Google is, and each of its commands once it is connected
$ gbrainio tool help google

The installer is a shell script for macOS and Linux. Read it before you run it.

Every Google command

These are the help pages the CLI prints for Google, run for real. The page and the CLI print from the same code, so the cheatsheet is what the CLI answers to today.
