WHAT IT DOES

What box_action does on CoWork OS

AI agents use box_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 box_action is rated Medium

While the tool includes read operations (search, read), the explicit mention of "manage" files/folders indicates it can perform reversible modifications to data in Box. This places it in the Write category rather than Read. Severity is medium because the blast radius is limited to the connected Box account, and changes are reversible.

From the tool's definition Tool description states it can "search, read, and manage files/folders" in a connected Box account. The inclusion of "manage" indicates write capabilities (create, modify, move, rename files/folders), not just read-only operations.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs box_action safely

PolicyLayer is an MCP gateway: it sits between your AI agents and CoWork OS, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For box_action, this is the rule to start with:

box_action Rate-limited

box_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.
