Why whmcs_delete_quote needs a policy

This tool irreversibly removes a quote from the WHMCS system. Deletion cannot be undone and represents a loss of business-critical data (quotes are part of the sales process in WHMCS). In the context of a financial management system, accidental or malicious deletion of quotes could disrupt business operations, audit trails, and customer relationships.

From the tool's definition Tool name 'whmcs_delete_quote' and description 'Delete a quote' explicitly indicate permanent removal of data. The verb 'delete' is a core destructive operation.

POLICY

How to control whmcs_delete_quote

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

policy.json

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

whmcs_delete_quote 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 Whmcs — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Free to start. No card required.
