THE RISK

Why delete-table needs a policy

Deleting a table destroys all data within it and cannot be undone. This is a classic destructive operation with high blast radius if an AI agent invokes it unintentionally or based on a misunderstood user request. It outranks Write (reversible modifications) and is the most severe category applicable.

From the tool's definition Tool name is 'delete-table' and description states 'Delete a table from the Xano workspace'. The verb 'delete' combined with the scope (entire table) indicates irreversible data removal.

POLICY

How to control delete-table

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

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete-table"
  ]
}

delete-table 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 Xano MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
