WHAT IT DOES

What add_section does on Webcake Storefront

AI agents use add_section 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 add_section is rated Medium

This tool modifies page structure by adding a new section to an existing page. This is a Create/Write operation within the page authoring workflow of the storefront builder. It is reversible (the section could be removed), so it does not qualify as Destructive. It does not execute arbitrary code, retrieve data only, move money, or trigger external operations—it simply modifies the page data structure.

From the tool's definition Tool description explicitly states 'Append a section to an EXISTING page'. The verb 'append' indicates modification of existing data (adding a section to a page structure).

Attacks that exploit this kind of access

RECOMMENDED RULE

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

add_section Rate-limited

add_section 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.

      "limits": [
        {
          "counter": "add_section_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

LIMIT THIS TOOL → Instant setup, no code required.

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