What n8n_delete_workflow does on Obsidian Elite RAG MCP Server
AI agents call n8n_delete_workflow to permanently remove resources in Obsidian Elite RAG MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why n8n_delete_workflow is rated Critical
This tool irreversibly deletes workflow data with no recovery mechanism. While the blast radius is contained to a single workflow (not a full system wipeout), the permanent nature and explicit warning meet the Destructive category definition. Severity is high rather than critical because deletion is limited to one workflow; critical would apply if it could mass-delete or destroy entire systems.
From the tool's definition Tool name explicitly states 'delete' and description states 'Permanently delete a workflow. This action cannot be undone.' The use of 'cannot be undone' is definitive evidence of irreversible data loss.
