WHAT IT DOES

What get_variants does on Shop

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

Parameters from the server's own tool schema.

RISK

Why get_variants is rated Low

Even though get_variants only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs get_variants safely

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

get_variants Allowed

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

policy.json

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

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

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