WHAT IT DOES

What meta_update_campaign does on Meta MCP Server

AI agents use meta_update_campaign to create or update resources in Meta MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Meta MCP Server environment.

THE RISK

Medium Risk

Why meta_update_campaign needs a policy

This tool creates or modifies campaign data reversibly. While it can change budget allocations (which have financial implications), the action itself is a write/update operation—the budget changes are reversible by updating again, not an irreversible financial transaction.

From the tool's definition Tool description states 'Updates an existing campaign' with optional parameters for name, status, daily_budget, lifetime_budget, and migrate_to_advantage_plus. These are reversible modifications to campaign configuration.

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

How to control meta_update_campaign

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_update_campaign:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "meta_update_campaign": {
      "limits": [
        {
          "counter": "meta_update_campaign_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

meta_update_campaign stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
