AI agents call plone_remove_single_block to permanently remove resources in Plone MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool removes content blocks from a Plone CMS item by block ID. Block deletion is an irreversible operation that destroys data structure and content layout. While scoped to a single block rather than entire content items, the destructive nature and inability to undo the action without recovery systems classifies this as Destructive rather than Write.
From the tool's definition Tool name contains 'remove' and description explicitly states 'Deletes a single block from a content item'. The verb 'deletes' combined with 'single block' indicates irreversible removal of content components.
