Why discord_notify needs a policy

This tool creates and sends a notification message to a Discord user, which is a write operation that modifies the state of the Discord channel/user inbox by adding a new message. It is reversible (the message can be deleted) and has no destructive, financial, or code execution consequences. The blast radius of misuse is low—an agent could spam notifications, but this causes only minor disruption.

From the tool's definition Tool name is 'discord_notify' and description states it 'Send a notification to the user via Discord.' The verb 'send' indicates creation/transmission of a message artifact.

POLICY

How to control discord_notify

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

policy.json

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

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