Permanently delete a list or document library.
AI agents call delete_list to permanently remove resources in SharePoint MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool irreversibly deletes entire SharePoint lists or document libraries, which cannot be undone without restoration from backups. The action destroys all contained items, metadata, and configurations associated with the list/library. This represents maximal data destruction at a structural level, warranting the Destructive category with critical severity.
From the tool's definition Tool description explicitly states 'Permanently delete a list or document library.' The word 'Permanently' indicates irreversible data loss.

Yes. Add a rate_limit block to the delete_list 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.
