Why create_forum_tag needs a policy

This tool creates a new forum tag, which is a reversible modification to channel metadata. It does not delete data (Destructive), execute arbitrary code (Execute), move money (Financial), or read-only retrieve data (Read). The operation is bounded by Discord's 20-tag limit and affects only forum channel organization.

From the tool's definition Tool description states 'Add a new tag to a forum channel' — a create/add operation that modifies forum configuration.

POLICY

How to control create_forum_tag

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 create_forum_tag:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_forum_tag": {
      "limits": [
        {
          "counter": "create_forum_tag_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

create_forum_tag stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. 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.
