WHAT IT DOES

What gmail_action does on CoWork OS

AI agents use gmail_action to create or update resources in CoWork OS, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your CoWork OS environment.

RISK

Why gmail_action is rated Medium

Although this tool includes read operations (search, read), the ability to draft and send messages constitutes write operations that create new data and modify account state. It does not delete messages irreversibly (so not Destructive), does not execute arbitrary code (so not Execute), and does not involve financial transactions (so not Financial).

From the tool's definition Tool description states: 'search, read, draft, label, archive, and send messages.' The capabilities include 'draft' and 'send messages,' which are write operations that create and transmit data.

Attacks that exploit this kind of access

RECOMMENDED RULE

gmail_action Rate-limited

gmail_action stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
