THE RISK

Critical Risk

Creating a subscription in Redis Cloud establishes a recurring financial obligation/commitment. Subscriptions involve payment and ongoing billing, placing this firmly in the Financial category. The blast radius is high as an AI agent could inadvertently create paid subscriptions incurring costs.

HOW TO CONTROL CREATE-ESSENTIAL-SUBSCRIPTION

PolicyLayer is an MCP gateway — it sits between your AI agents and Redis Cloud API MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for create-essential-subscription:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create-essential-subscription": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to create-essential-subscription is blocked until a human approves it. The rest of the server keeps working.
