Deletes a forum post or thread with an optional reason
AI agents call discord_delete_forum_post to permanently remove resources in MCP-Discord — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
The tool permanently removes forum posts/threads from Discord, which cannot be undone. This matches the Destructive category definition: 'irreversibly deletes or overwrites data, or actions that cannot be undone.' While the blast radius is somewhat scoped to specific posts rather than entire channels or servers, the operation is still high-severity due to potential loss of important conversations and community…
From the tool's definition Tool name explicitly includes 'delete' and description states 'Deletes a forum post or thread' — this is an irreversible data removal operation.
