WHAT IT DOES

What install_app does on Webcake Storefront

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

RISK

Why install_app is rated Medium

Installing an app modifies the site configuration by adding a new application and enabling its features. This is a reversible Write operation (the app can typically be uninstalled), not a Read (no data retrieval), Execute (no arbitrary code execution), Destructive (reversible), or Financial operation.

From the tool's definition Tool name "install_app" and description "Install (register) an application on the current site so its features become usable" indicates creating/registering a new application resource on the storefront.

install_app Rate-limited
