Delete a workflow.
AI agents call n8n_delete_workflow to permanently remove resources in Mcp N8n — 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 permanently removes automation logic and associated configurations. This fits the Destructive category (delete operations that cannot be undone). The severity is critical because workflows may be integral to business operations, and their loss could disrupt automated processes, cause data loss, or halt critical business functions.
From the tool's definition Tool name 'n8n_delete_workflow' combined with description 'Delete a workflow' explicitly indicates irreversible deletion of workflow data.
Attacks that exploit this kind of access
Delete a workflow. It is categorised as a Destructive tool in the Mcp N8n MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Mcp N8n MCP server in PolicyLayer and add a rule for n8n_delete_workflow: 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 Mcp N8n. Nothing to install.
n8n_delete_workflow 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 n8n_delete_workflow 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 n8n_delete_workflow. 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.
n8n_delete_workflow is provided by the Mcp N8n MCP server (lyzetam/mcp-n8n). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
