Why playwright_stop_video_recording needs a policy

This tool stops an ongoing video recording and saves the resulting file to disk. It creates/writes a new file (the saved video), which is a reversible Write operation. It does not execute arbitrary code, delete data, or involve financial transactions. Severity is medium because it affects persistent storage and could be misused to capture and store sensitive browser session content.

From the tool's definition Stop video recording and save the file with optional annotations

POLICY

How to control playwright_stop_video_recording

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

policy.json

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

playwright_stop_video_recording 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 RunAutomation 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.
