Why crow_plex_on_deck needs a policy

This tool queries data from a Plex media server to retrieve a viewing list. It performs a simple data retrieval operation with no capability to create, modify, delete, or execute actions. The only information exposed is media metadata about items on a user's watchlist, which presents minimal security risk.

From the tool's definition Tool retrieves 'On Deck list — items ready to continue watching or recently added unwatched items'. The verb 'Get' and the read-only nature of querying a viewing list with no modification or side effects.

POLICY

How to control crow_plex_on_deck

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_on_deck:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "crow_plex_on_deck": {}
  }
}

crow_plex_on_deck is read-only, so it stays allowed — but 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.
