Kit from the command line
Email marketing: subscribers, broadcasts, sequences and stats.
gbrain.io
Email marketing: subscribers, broadcasts, sequences and stats. GBrain gives Kit, and every other application you connect, a command line.
One price for one person: Kit and every other application GBrain connects, from a terminal or any AI. Cancel any time.
Kit is connected on its own sign-in page, in the browser. A key or a sign-in never passes through the terminal.
# AI agents: read gbrain.io/llms.txt curl -sSL https://gbrainio.terminalwire.sh | bash gbrainio terminal connect
The installer is a shell script for macOS and Linux. Read it before you run it.
# Every Kit command, once Kit is connected gbrainio tool help kit-mcp
Kit, formerly ConvertKit, is an email marketing and newsletter platform for creators. Connected to a workspace, GBrain can answer “which broadcast last month had the best click rate?”, tag a group of subscribers, or draft the next newsletter.
Each terminal reaches Kit at the level set for it in the browser: Off, or On, which is every command Kit's server lists. A terminal reads its level and never raises it.
Each of Kit's commands stops at 1,000 actions a day on the account it reaches, whichever terminal or AI asks, and starts again at midnight UTC. Only that command stops.
Each command a terminal runs on Kit is a row on GBrain's activity log: which terminal, which account, what it did and whether it was allowed, refusals included. gbrainio activity ls --tool kit-mcp reads it back.
Kit's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once Kit is connected, gbrainio tool help kit-mcp says what each of them does, and gbrainio tool ls lists them with everything else the terminal can run. Claude Code and Codex run the same commands, at the same level, on the same record.
GBrain reaches Kit at its own server, app.kit.com. On Kit's own pages: its website, how the connection works, its terms of service and its privacy policy.
The GBrain Tools command line works with every other application GBrain connects, each with a page like this one.
Personal is $49 a month for one person. Connect Kit in the browser, and say how far each terminal and each AI may go with it. Change any of it, or take all of it back, whenever you want.
