THE RISK

Why list-billing-group-cost-reports needs a policy

This tool retrieves billing and cost data without modifying or deleting records. However, the sensitivity of billing/financial information warrants medium severity due to potential for unauthorized access to cost details. Confidence is moderate (0.75) because the description is empty; the classification relies primarily on the tool name pattern and context from an AWS Prometheus billing context.

From the tool's definition Tool name 'list-billing-group-cost-reports' indicates retrieval of cost/billing reports. The 'list' prefix and lack of modification verbs (create, delete, update) suggest a read-only query operation.

POLICY

How to control list-billing-group-cost-reports

PolicyLayer is an MCP gateway — it sits between your AI agents and Prometheus MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-billing-group-cost-reports:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "list-billing-group-cost-reports": {}
  }
}

list-billing-group-cost-reports is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Prometheus MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
