THE RISK

Medium Risk

Why add_video_notes needs a policy

This tool creates new content (video sticky notes) within PDFs, which is reversible modification. While embedding videos could introduce security concerns (malicious video links, phishing), the primary action is writing/modifying document structure, not executing arbitrary code or deleting data.

From the tool's definition Tool name 'add_video_notes' and description 'Add video sticky notes that embed and launch video content' indicate creation/modification of PDF content through embedded video elements.

POLICY

How to control add_video_notes

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

policy.json

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

add_video_notes 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
