Delete a tag. Removes it from all workflows that use it. Args: - id (string): Tag ID to delete
AI agents call n8n_delete_tag to permanently remove resources in n8n MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting a tag is a destructive action that cannot be undone. It removes metadata from potentially many workflows simultaneously, which constitutes data loss. While the blast radius is scoped to tag metadata rather than critical workflow logic or data, the operation is irreversible and affects multiple resources.
From the tool's definition Tool name includes 'delete' and description states 'Delete a tag. Removes it from all workflows that use it.' This is an irreversible operation that modifies multiple workflows.
Attacks that exploit this kind of access
Delete a tag. Removes it from all workflows that use it. Args: - id (string): Tag ID to delete. It is categorised as a Destructive tool in the n8n MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the n8n MCP Server MCP server in PolicyLayer and add a rule for n8n_delete_tag: 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 MCP Server. Nothing to install.
n8n_delete_tag 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_tag 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_tag. 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_tag is provided by the n8n MCP Server MCP server (verzth/mcp-n8n). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
