Why crow_media_get_article needs a policy

This tool retrieves existing article data by identifier. It performs a read-only query with no capability to modify, delete, or execute operations. The blast radius is minimal; misuse would only expose article content the requester might not have permission to access, a confidentiality concern rather than a destructive or operational risk.

From the tool's definition Tool name contains 'get' and description states 'Get full article content by ID' — a retrieval operation with no modification or side effects.

POLICY

How to control crow_media_get_article

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_media_get_article:

policy.json

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

crow_media_get_article 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.
