WHAT IT DOES

What create_font_group does on Webcake Storefront

AI agents use create_font_group 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_font_group is rated Medium

This tool creates a new font group resource, which modifies the storefront configuration. It is a Write operation because it creates data that can be modified or removed later without permanent consequences. Severity is medium because misconfiguration could affect site appearance but does not directly expose, move, or destroy critical data. The blast radius is limited to font styling impact on the storefront.

From the tool's definition Tool name 'create_font_group' and description 'Create a font group' indicate creation of a new resource (font configuration). The action is reversible via update/delete operations typical in storefront builders.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs create_font_group safely

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

create_font_group Rate-limited

create_font_group 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.
