WHAT IT DOES

What meta_list_ads does on Meta MCP Server

AI agents call meta_list_ads to retrieve information from Meta MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why meta_list_ads needs a policy

This tool performs read-only retrieval of ad information with filtering and pagination capabilities. It has no side effects, does not create, modify, or delete data, and does not execute external operations. The blast radius of misuse is minimal—an unauthorized agent could enumerate ads but cannot alter campaigns, spend money, or affect business operations.

From the tool's definition Tool lists ads filtered by adset_id, campaign_id, or ad_account_id with optional status filters and pagination. No modification, deletion, or execution occurs—purely retrieves and queries ad data.

Documented attack patterns abuse exactly the kind of access meta_list_ads gives an agent:

POLICY

How to control meta_list_ads

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_list_ads:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "meta_list_ads": {}
  }
}

meta_list_ads is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
