Why meta_upload_ad_video needs a policy

While not destructive or code-executing, unauthorized video uploads could be used to inject malicious, fraudulent, or inappropriate ad content at scale across Facebook/Instagram, affecting brand reputation, user experience, and potentially violating platform policies.

From the tool's definition Tool name 'meta_upload_ad_video' and description 'Uploads a video to an ad account' indicate creation/modification of advertising assets.

POLICY

How to control meta_upload_ad_video

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_upload_ad_video:

policy.json

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

meta_upload_ad_video 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.
