WHAT IT DOES

What install_asset does on Sbox

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

RISK

Why install_asset is rated Medium

This tool creates or modifies project data by installing assets, which is reversible (assets can typically be uninstalled). It does not execute arbitrary code, delete data irreversibly, or move money. While it could potentially introduce malicious or incompatible assets if the ident parameter is controlled by an untrusted source, the primary action is additive/write-based rather than Execute or Destructive.

From the tool's definition Tool name 'install_asset' and description indicating installation of asset packages into a project. Installation is a write operation that modifies project state by adding new assets.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs install_asset safely

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

install_asset Rate-limited

install_asset 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.
