THE RISK

Why discord_delete_message needs a policy

This tool permanently deletes data (Discord messages) with no recovery option. While scoped to the user's own messages, an AI agent with access could be tricked into deleting important communications, conversation history, or evidence. The irreversible nature and the explicit statement that it "cannot be undone" place this firmly in the Destructive category rather than Write.

From the tool's definition Tool description states: "Delete one of your own messages. This action is permanent and cannot be undone." The words "permanent" and "cannot be undone" explicitly indicate irreversible deletion.

POLICY

How to control discord_delete_message

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

policy.json

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

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