🗑️ Delete (archive) a workflow. This removes the workflow from n8n.
AI agents call delete_workflow to permanently remove resources in n8n Workflow Builder — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes workflows from the n8n system. While described as archiving (which might suggest reversibility in some systems), the explicit use of 'delete' and 'removes' indicates an irreversible action that cannot be undone without restore operations outside the tool's scope. This qualifies as Destructive rather than Write, as it destroys rather than modifies data.
From the tool's definition Tool description explicitly states 'Delete (archive) a workflow. This removes the workflow from n8n.' The verb 'delete' paired with 'removes' indicates irreversible removal of data/configurations.
Attacks that exploit this kind of access
🗑️ Delete (archive) a workflow. This removes the workflow from n8n. It is categorised as a Destructive tool in the n8n Workflow Builder MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the n8n Workflow Builder MCP server in PolicyLayer and add a rule for 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 n8n Workflow Builder. Nothing to install.
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 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 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.
delete_workflow is provided by the n8n Workflow Builder MCP server (schimmilab/n8n-workflow-builder). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
