Kernel from the command line
Cloud browsers for agents to browse, fill forms and take screenshots.
gbrain.io
Cloud browsers for agents to browse, fill forms and take screenshots. GBrain gives Kernel, and every other application you connect, a command line.
One price for one person: Kernel and every other application GBrain connects, from a terminal or any AI. Cancel any time.
Kernel 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 Kernel command, once Kernel is connected gbrainio tool help kernel
Kernel runs Chromium browsers in the cloud for AI agents, with saved profiles, proxies and video replays of each session. Connected to a workspace, GBrain can answer “what does the vendor portal list for this invoice?” by sending a browser to look, fill in a web form that has no API, or capture a screenshot of a page as it is right now.
Signing in happens on Kernel’s own page, and browser time counts against the Kernel account.
Each terminal reaches Kernel at the level set for it in the browser: Off, or On, which is every command Kernel's server lists. A terminal reads its level and never raises it.
Each of Kernel'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 Kernel 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 kernel reads it back.
Kernel's own server lists its commands only to a terminal that has connected it, so they are not on this page. Once Kernel is connected, gbrainio tool help kernel 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 Kernel at its own server, mcp.onkernel.com. On Kernel'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 Kernel 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.
