Bulk delete messages from a Discord channel. Defaults to dry-run mode.
AI agents call discord.message.bulk_delete to permanently remove resources in Discord MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Bulk deletion of messages is an irreversible destructive action that cannot be undone. Even though the tool defaults to dry-run mode (which mitigates risk), the core capability is destructive. An AI agent with access to this tool could maliciously or accidentally delete entire conversation histories, evidence, or important communication records.
From the tool's definition Tool name 'bulk_delete' and description 'Bulk delete messages from a Discord channel' directly indicate irreversible deletion of data. The term 'bulk' suggests this can affect multiple messages at once, amplifying the blast radius.

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.bulk_delete:
{
"version": "1",
"default": "deny",
"hide": [
"discord.message.bulk_delete"
]
}discord.message.bulk_delete disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
