THE RISK

Low Risk

Why azure_cost_estimate needs a policy

The tool performs cost estimation by analyzing usage patterns against pricing data. This is fundamentally a read operation: it queries Azure pricing information (consistent with the server's purpose of 'real-time access to Azure retail pricing information') and returns calculated estimates. There is no execution of infrastructure changes, no financial commitment, and no data modification.

From the tool's definition Tool description states 'Estimate Azure costs based on usage patterns' — a read-only operation that queries pricing data to generate estimates.

POLICY

How to control azure_cost_estimate

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

policy.json

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

azure_cost_estimate 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 Azure Pricing 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.
