Why meta_delete_saved_audience needs a policy

Deletion of a saved audience cannot be undone and represents permanent removal of data. While the blast radius is limited to audience segments (not financial or system-critical), the irreversible nature of deletion places this in the Destructive category rather than Write.

From the tool's definition Tool name 'meta_delete_saved_audience' and description 'Deletes a saved audience' explicitly perform deletion, which is irreversible.

POLICY

How to control meta_delete_saved_audience

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_saved_audience:

policy.json

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

meta_delete_saved_audience 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.
