WHAT IT DOES

What Zip_File does on Files Com

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

RISK

Why Zip_File is rated Medium

The tool creates a new file artifact by compressing data, which is a reversible write operation. While it doesn't directly modify or delete existing data, it does create a new file in the destination path. If an AI agent misuses this tool, it could consume disk space or create unintended archives, but the operation itself is reversible (the ZIP can be deleted).

From the tool's definition Tool creates a new ZIP file ("Create a ZIP from one or more paths and save it to a destination path"), which is a data creation and storage operation.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs Zip_File safely

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

Zip_File Rate-limited

Zip_File 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.

The button opens the PolicyLayer dashboard: create your workspace, connect Files Com, apply this rule, and every Zip_File call is checked against it from then on.
