WHAT IT DOES

What list_domains does on Webcake Storefront

AI agents call list_domains to retrieve information from Webcake Storefront without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why list_domains is rated Low

This tool retrieves and queries domain information associated with a site. It performs no data modification, deletion, code execution, or financial operations. The blast radius of misuse is minimal—an attacker could only learn what domains are configured for a site, which is reconnaissance-level exposure.

From the tool's definition Tool name 'list_domains' and description 'List custom domains attached to the site' indicate a retrieval operation with no modification or side effects.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs list_domains 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 list_domains, this is the rule to start with:

list_domains Allowed

list_domains is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list_domains": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Webcake Storefront, apply this rule, and every list_domains call is checked against it from then on.
