Critical Risk

Why delete_draft needs a policy

This tool permanently removes data (draft invoices) from the Billingo invoicing system. Deletion is an irreversible destructive action that cannot be undone, placing it in the Destructive category. Severity is high because an AI agent with unchecked access could delete important financial records, though the blast radius is somewhat limited by the fact that only drafts (not finalized invoices) are affected.

From the tool's definition Tool name 'delete_draft' combined with description indicating deletion of draft invoices ('Piszkozat számla törlése' translates to 'Delete draft invoice'). The operation is irreversible—once a draft is deleted, it cannot be recovered.

How to control delete_draft

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

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_draft"
  ]
}

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