Why list_invites needs a policy

This tool retrieves and queries invite link data without modifying server state, permissions, or membership. While invite links could theoretically be sensitive, listing them represents passive information retrieval rather than an action with adverse effects.

From the tool's definition Tool name 'list_invites' and description 'List all active invite links for the Discord server, including usage stats and expiration info' indicate a retrieval operation with no side effects.

POLICY

How to control list_invites

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 list_invites:

policy.json

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

list_invites 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.
