Why pt_rate_video needs a policy

This tool writes a rating (like/dislike/unrate) to an external video platform. It modifies data reversibly (ratings can be changed or removed), so it falls under Write. Misuse could spam ratings on videos at scale (up to 60/hour), but it does not delete data or move money, making severity medium.

From the tool's definition Like / dislike / unrate a video by numeric id

POLICY

How to control pt_rate_video

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

policy.json

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

pt_rate_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 Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
