Why show_group_live_video needs a policy

This tool causes the VMS program to display live video streams, which is an external operation that triggers UI behavior in a third-party application. While it reads video data, the primary action is invoking/controlling the VMS program's playback interface, making it Execute rather than Read. Misuse could expose live camera feeds or disrupt operator workflows.

From the tool's definition 'Show the live video streams' and 'in the VMS program' — triggers an external UI/display action in the VMS application, not merely retrieving data

POLICY

How to control show_group_live_video

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

policy.json

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

show_group_live_video 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 Server - VMS Integration — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
