AI agents call discord_prune_members 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.
This tool permanently removes Discord server members based on inactivity criteria. While it includes a dry_run safeguard to preview changes first, the actual removal operation is irreversible—members must manually rejoin the server. This constitutes a destructive action that cannot be undone. The blast radius is high because bulk member removal could significantly disrupt community structure and member experience.
From the tool's definition Tool description explicitly states: 'Remove members who have been inactive', 'Removal is irreversible (members must rejoin)', and 'Requires the Kick Members permission.' The term 'irreversible' directly indicates destructive action.

Remove members who have been inactive (no roles, not seen) for a number of days. SAFE BY DEFAULT: dry_run is true unless explicitly set to false, so call it first to preview the count, then re-call with dry_run:false to actually remove them. Removal is irreversible (members must rejoin). Requires the Kick Members permission. 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_prune_members: 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_prune_members 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_prune_members 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_prune_members. 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_prune_members 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.
