Delete an execution
AI agents call n8n_delete_execution 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.
This tool permanently removes execution data from n8n, which constitutes destructive action. Execution records are critical for auditing, debugging, and compliance purposes. An AI agent with access to this tool could delete evidence of workflow activities, compromise audit trails, or destroy records needed for incident investigation.
From the tool's definition Tool name explicitly contains 'delete' and description states 'Delete an execution'. Execution records in n8n are historical audit trails that document workflow runs, including logs, data processed, and state changes.
Attacks that exploit this kind of access
Delete an execution. 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_execution: 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_execution 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_execution 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_execution. 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_execution is provided by the n8n MCP Server MCP server (shravan1610/n8n-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
