Google Calendar from the command line
List, add, change and cancel events without leaving the terminal.
gbrain.io
List, add, change and cancel events without leaving the terminal.
Calendar has two levels rather than four: read what is on it, or write to it. A client granted read can answer what a week looks like and cannot move anything in it.
Each of the last three opens a browser tab, does one thing, and hands the terminal back.
curl -sSL https://gbrainio.terminalwire.sh | bash # install it gbrainio terminal connect # set the terminal up and connect it gbrainio tool gcal open # connect the account gbrainio terminal open # turn Google Calendar on for the terminal
The installer is a shell script for macOS and Linux. Read it before you run it.
This is gbrainio tool gcal,

Claude Code, Cursor and Codex reach the same Google Calendar through MCP, on the same permission and the same record.
One permission, one daily ceiling, one record, across every client that asks.
