How to control printful_get_variant_prices

PolicyLayer is an MCP gateway — it sits between your AI agents and Printful MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for printful_get_variant_prices:

policy.json

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