AI agents call discord_bulk_ban to permanently remove resources in Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Banning multiple users simultaneously is an irreversible destructive action at scale — bans remove users from the server and cannot be automatically undone. The bulk nature (many users in a single call) amplifies the blast radius enormously; a misuse or mistake could result in mass wrongful bans across an entire Discord guild.

Attacks that exploit this kind of access
Ban many users in a single call, intended for raid mitigation. SAFE BY DEFAULT: dry_run is true unless explicitly set to false, so call it first to preview the exact list of user IDs that would be banned, then re-call with dry_run:false to actually ban them. Requires both the Ban Members and Manage Server permissions. Returns counts of banned vs failed users; Discord rejects the whole call with an error if no user could be banned. Use discord_ban_member for a single ban with finer control. It is categorised as a Destructive tool in the Discord MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Discord MCP server in PolicyLayer and add a rule for discord_bulk_ban: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Discord. Nothing to install.
discord_bulk_ban is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the discord_bulk_ban rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for discord_bulk_ban. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
discord_bulk_ban is provided by the Discord MCP server (@pasympa/discord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
