Why crow_plex_control needs a policy

This tool triggers external operations on a Plex media player (play, pause, stop, skip, seek, volume adjustment). These are real-time control actions that affect an active media session on an external system, fitting the Execute category. Misuse could disrupt ongoing playback sessions, but the blast radius is limited to media control with no data destruction or financial impact.

From the tool's definition Transport controls for Plex playback: play, pause, stop, skip, seek, volume

POLICY

How to control crow_plex_control

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 crow_plex_control:

policy.json

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

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