Why github_cost_estimate needs a policy

This tool performs cost estimation and forecasting based on input parameters (team size, etc.). It reads/queries pricing data and performs calculations to return estimates. It does not execute transactions, modify data, delete anything, or commit actual financial obligations. The output is informational (an estimate), not an actionable financial commitment.

From the tool's definition Tool name 'github_cost_estimate' and context indicating it 'Estimate[s] monthly and annual GitHub costs' — a calculation/query operation that retrieves or computes pricing data without modifying any systems or committing financial obligations.

POLICY

How to control github_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 github_cost_estimate:

policy.json

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

github_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.
