WHAT IT DOES

What discord_find_message does on Discord User

AI agents call discord_find_message to retrieve information from Discord User without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

THE RISK

Low Risk

Why discord_find_message needs a policy

This tool retrieves historical message data from Discord channels without altering state. It performs read-only queries (via guild search API or channel scanning) to locate messages matching specified criteria. The fallback to direct channel scanning when guild search is blocked is still a retrieval operation. No side effects, no data modification, no code execution, and no destructive capability.

From the tool's definition Tool description explicitly states it "finds messages" by querying author, content, or date range. The mechanism is search/scan operations with no modification, deletion, or execution. No mention of creating, editing, or destructive actions.

POLICY

How to control discord_find_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_find_message:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "discord_find_message": {}
  }
}

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