Why meta_get_minimum_budgets needs a policy

This is a pure read/query operation that retrieves metadata about budget constraints from the ad account. It performs no data modifications, executions, or destructive actions. The low severity reflects that misuse (e.g., querying another account's budgets if access controls fail) would only expose informational data, not enable financial transactions or damage.

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "meta_get_minimum_budgets": {}
  }
