THE RISK

Why discord.message.list_recent needs a policy

This tool only queries and retrieves existing message data from a channel. It has no side effects, does not modify data, execute commands, or trigger external operations. The read-only nature and bounded scope (recent messages from a single channel) result in minimal blast radius if misused by an AI agent.

From the tool's definition discord.message.list_recent retrieves recent messages from a Discord channel with no modification, deletion, or execution capability.

POLICY

How to control discord.message.list_recent

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "discord.message.list_recent": {}
  }
}

discord.message.list_recent is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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