Why meta_delete_ad_rule needs a policy

The tool performs permanent deletion of an ad rule, which cannot be undone. While the blast radius is scoped to ad management (not financial transactions or data exfiltration), deletion of advertising rules could disrupt active campaigns or automation workflows. Severity is high rather than critical because the impact is isolated to ad operations, but it is clearly Destructive per the classification rules.

From the tool's definition Tool name contains 'delete' and description states 'Deletes an automated ad rule' — this is an irreversible removal of configuration data.

POLICY

How to control meta_delete_ad_rule

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_delete_ad_rule:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "meta_delete_ad_rule"
  ]
}

meta_delete_ad_rule disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Meta 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.
