Delegate scoped API access to AI agents
GBrain Tools
Connect your accounts to AI assistants with scoped permissions.
Meet GBrain Tools
GBrain Tools connects personal and work applications to AI assistants without handing the assistants the underlying account credentials. Users connect services such as Gmail, GitHub, Notion, and Stripe once, then access their tools through MCP or a command-line interface. This lets an assistant work with existing accounts while GBrain handles the authenticated calls.
Permissions are set for each application and AI client. Users can restrict reading or changes, set access expiration dates and daily tool limits, and revoke a connection when it is no longer needed. An activity log records successful and refused actions, providing a place to review how connected assistants are using those accounts.
