WHAT IT DOES

What create_saved_filter does on Webcake Storefront

AI agents use create_saved_filter 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 create_saved_filter is rated Medium

The tool creates a new saved filter, which is a data creation operation (Write category). The severity is low because saved filters are metadata configurations that do not affect core business data, inventory, orders, or financial records. The action is reversible—filters can be modified or deleted. No code execution, deletion, or financial impact is involved.

From the tool's definition Tool name 'create_saved_filter' and description 'Create a saved table filter' indicate creation of a new filter configuration. This is a write operation that creates data persistently but reversibly.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_saved_filter safely

create_saved_filter Rate-limited

create_saved_filter 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.
