Why create_video_from_images needs a policy

This tool runs FFmpeg as an external process to combine image sequences into a video file. It executes a media processing operation whose effects depend on the input arguments (image paths, frame rate, output format, etc.). While it creates a new file (Write-like), the execution of an external binary with variable arguments places it firmly in Execute.

From the tool's definition 'Create a video from a sequence of images' — triggers FFmpeg execution to process and combine image files into a video output

POLICY

How to control create_video_from_images

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP FFmpeg Helper, and nothing reaches the server without passing your rules. This is the rule we recommend for create_video_from_images:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_video_from_images": {
      "limits": [
        {
          "counter": "create_video_from_images_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_video_from_images stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Create a free account and register MCP FFmpeg Helper — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
