THE RISK

Critical Risk

Why delete_forum_tag needs a policy

The tool performs an irreversible deletion operation (removing a tag). While the blast radius is somewhat limited compared to deleting messages or banning users, it permanently destroys data/structure that cannot be easily recovered without manual recreation. This is more severe than Write (which is reversible) but less critical than destructive actions affecting many members or messages at scale.

From the tool's definition Tool name contains 'delete' and description states 'Remove a tag from a forum channel.' This irreversibly removes metadata/organizational structure from the Discord server.

POLICY

How to control delete_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 delete_forum_tag:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_forum_tag"
  ]
}

delete_forum_tag disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
