What create_contact does on Webcake Storefront
AI agents use create_contact 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.
Why create_contact is rated Medium
This tool creates a new contact record in the storefront system. Contact creation is reversible (contacts can be deleted), so it falls under Write rather than Destructive. The blast radius is medium: misuse could result in spam contacts, data pollution, or manipulation of customer/contact lists, but the core business operations (products, orders, payments) are not directly imperiled.
From the tool's definition Tool name 'create_contact' and description 'Create a contact entry' indicate data creation. The verb 'Create' and the action of adding a new contact entry are characteristic Write operations that modify data reversibly.
Attacks that exploit this kind of access
The rule that runs create_contact 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_contact, this is the rule to start with:
create_contact 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 Webcake Storefront, apply this rule, and every create_contact call is checked against it from then on.
