Why discord_embed needs a policy

This tool creates and sends a formatted Discord message (an embed). It is a Write operation because it creates new data (the embed message) that is reversibly stored in Discord. It has low severity because message sending has minimal blast radius—messages can be deleted, are non-destructive, and do not affect system integrity, financial assets, or execute external code.

From the tool's definition Tool name 'discord_embed' and description 'Send a rich embed message to Discord' indicate creation of new message content. The parameters (title, description, color, fields) are for formatting and sending a message, which is a create operation.

How to control discord_embed

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_embed:

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "discord_embed": {
      "limits": [
        {
          "counter": "discord_embed_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

discord_embed 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.

  1. Create a free account and register Discord Mcp Agent — nothing to install.
  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
