WHAT IT DOES

What list_promotions does on Webcake Storefront

AI agents call list_promotions 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_promotions is rated Low

This tool queries and retrieves promotion data without creating, modifying, or deleting any resources. It is a standard read operation with minimal blast radius — exposure only enables viewing of existing promotions metadata, not altering business logic or customer data.

From the tool's definition Tool name 'list_promotions' and description 'List all promotions/discounts' indicate a read-only query operation. The phrase 'metadata only' and reference to 'Use get_promotion for full details' confirm this retrieves information without modification.

Attacks that exploit this kind of access

RECOMMENDED RULE

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

list_promotions Allowed

list_promotions 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_promotions": {}
  }
}

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_promotions call is checked against it from then on.
