THE RISK

Low Risk

Why shortcode_list needs a policy

This tool only queries and returns information about existing shortcode configurations. It performs no side effects, does not execute code or commands, and does not modify or delete data. It is a straightforward read operation that provides visibility into how the migration process will handle shortcodes.

From the tool's definition Tool name is 'shortcode_list' and description states 'List all configured shortcode handling rules for a site' — a pure retrieval operation with no modification or execution capability.

POLICY

How to control shortcode_list

PolicyLayer is an MCP gateway — it sits between your AI agents and WP Astro MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for shortcode_list:

policy.json

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

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