Delete a workflow
AI agents call workflow_delete to permanently remove resources in N8n Fabric — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a workflow is an irreversible action that destroys automated business logic and cannot be restored without external backups. This falls squarely into the Destructive category. The severity is critical because an AI agent deleting production workflows could paralyze business automation processes, halt critical integrations, and cause operational outages.
From the tool's definition Tool name is 'workflow_delete' and description states 'Delete a workflow'. The verb 'delete' combined with the irreversible nature of removing a workflow indicates destruction of automation logic that cannot be undone.
Attacks that exploit this kind of access
Delete a workflow. It is categorised as a Destructive tool in the N8n Fabric MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the N8n Fabric MCP server in PolicyLayer and add a rule for workflow_delete: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches N8n Fabric. Nothing to install.
workflow_delete is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the workflow_delete 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.
Set action: deny in the PolicyLayer policy for workflow_delete. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
workflow_delete is provided by the N8n Fabric MCP server (ry-ops/n8n-fabric). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
workflow_delete is one line of N8n Fabric's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
