n8n_archive_workflow · n8n MCP Server MCP: Risk & Policy

WHAT IT DOES

What n8n_archive_workflow does on n8n MCP Server

AI agents use n8n_archive_workflow to create or update resources in n8n MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your n8n MCP Server environment.

WHY IT NEEDS A POLICY

Why n8n_archive_workflow needs a policy

Archiving is a Write operation because it modifies data state (marks workflow as archived) but is fully reversible via n8n_unarchive_workflow. It is not Destructive because the action can be undone. Severity is medium because archiving a workflow could disrupt automation if done on active workflows, but the impact is recoverable and scoped to that single workflow.

From the tool's definition 'Soft-delete a workflow by archiving it. Can be restored with n8n_unarchive_workflow.' — the tool modifies workflow state reversibly without permanent deletion.
