A permission level for every application an AI can reach

ChatGPT MCP

Claude MCP

OpenClaw MCP

one MCP address

Gmail

Calendar

Web search

Memory

Claude Code MCP

Cursor MCP

Terminal CLI

Paste one address into each AI and it has the same accounts, at the same permission levels, with the same daily limits and the same record. Add an account here and every one of them can use it on its next call.

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.

Two days of unread mail, from the terminal or from an AI running the same command.

One command line for every connected account

Gmail and Calendar are two. Every account answers the same way, to a person or an AI.

GBrain holds the keys to every account you connect, and never hands one to an AI. An AI gets the results of the calls it was allowed to make; one that is compromised finds no keys where it lives.

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.

A circuit breaker on every tool, for when an AI goes haywire

Every tool on every account has a daily line. Cross it and that tool trips; nothing else does.

A log of every action an AI takes with connected accounts

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

Access that ends when you say, and on a date you pick

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