THE RISK

Critical Risk

Why meta_create_adset needs a policy

Creating an ad set directly commits advertising budget (financial obligation) to Meta's ad platform. The tool accepts monetary parameters (daily_budget, lifetime_budget in cents) and links to a billing event, meaning misuse could result in unintended ad spend. This constitutes a financial commitment, making Financial the most severe applicable category.

From the tool's definition Creates a new ad set within a campaign with 'daily_budget' and 'lifetime_budget' parameters measured in cents, committing financial spend obligations on an ad account.

POLICY

How to control meta_create_adset

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "meta_create_adset": {
      "deny_if": [
        {
          "conditions": [],
          "on_deny": "Requires human approval."
        }
      ]
    }
  }
}

Any call to meta_create_adset is blocked until a human approves it. The rest of the server keeps working.
