Why n8n_manage_datatable needs a policy

The tool supports deleteTable and deleteRows which are irreversible destructive operations. Per the rules, when a tool spans categories, the most severe applies — Destructive > Execute > Write > Read. Misuse by an AI agent could permanently destroy entire data tables and their contents, warranting critical severity.

From the tool's definition Actions include: deleteTable, deleteRows — irreversible deletion of entire tables or rows; also includes createTable, updateTable, insertRows, updateRows, upsertRows covering the full data lifecycle

POLICY

How to control n8n_manage_datatable

PolicyLayer is an MCP gateway — it sits between your AI agents and N8n, and nothing reaches the server without passing your rules. This is the rule we recommend for n8n_manage_datatable:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "n8n_manage_datatable"
  ]
}

n8n_manage_datatable disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register N8n — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
