THE RISK

Low Risk

Why get_role_permissions needs a policy

This tool retrieves and displays existing permission data without modifying, deleting, or executing any actions. It poses minimal risk as it merely queries the current state of role permissions in the Discord server.

From the tool's definition Tool description states 'View all permissions granted to a specific role' — a query operation with no side effects. The verb 'view' and the read-only nature of permission inspection confirm this is information retrieval only.

POLICY

How to control get_role_permissions

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

policy.json

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

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