Why crow_plex_play needs a policy

This tool executes a command on an external system (Plex client) to perform a specific operation. While not destructive or financial, it initiates real-world effects (starting media playback) that depend on the supplied parameters. An AI agent given this tool could start unwanted playback, consume bandwidth, or trigger device actions without proper authorization.

From the tool's definition Tool description states 'Start playback of an item on a Plex client', which is an action that triggers external operations (media playback control) whose effects depend on the arguments provided (client_id, item to play).

POLICY

How to control crow_plex_play

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_play:

policy.json

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

crow_plex_play 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.
