Why meta_ads_conversions_send_purchase needs a policy

While it doesn't directly move money, it sends conversion tracking data that affects ad bidding, attribution, and campaign optimization — and can influence financial spend indirectly. The primary action is 'sends' an event to an external system, making it Execute.

POLICY

How to control meta_ads_conversions_send_purchase

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "meta_ads_conversions_send_purchase": {
      "limits": [
        {
          "counter": "meta_ads_conversions_send_purchase_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

meta_ads_conversions_send_purchase stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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