Tools, feature by feature

The accounts it reaches, and what each AI may do with them.

The same tools in every AI that speaks MCP

One address, pasted once into ChatGPT, Claude, Claude Code or Cursor. Each gets the same accounts and rules.

Gmail and Calendar from the command line, for people and coding agents

Gmail, Calendar and web search from a terminal. Claude Code and Codex run the same commands.

See how it works

Passwords and API keys never reach the AI

Connected accounts are held by gbrain. An AI gets the result of a call, never the key.

See how it works

A permission level for every application an AI can reach

Gmail has four levels, Calendar two, web search is on or off. Set per application; every AI follows.

See how it works

A log of every call an AI makes with connected accounts

One row per call. Who asked, which AI, which account, what it did, whether it was allowed.

See how it works

A kill switch for every AI, and an expiry date

Turn an AI off and its next call is refused. Every AI's access also has an end date.
