THE RISK

Why delete_webhook needs a policy

Deleting a webhook irreversibly removes an event subscription and its associated integrations. This cannot be undone without manual recreation, making it a Destructive operation rather than a reversible Write.

From the tool's definition Tool name is 'delete_webhook' with description 'Delete an event subscription (webhook)'. The verb 'delete' combined with 'event subscription' indicates irreversible removal of a webhook configuration.

POLICY

How to control delete_webhook

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

policy.json

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

delete_webhook 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 Qualtrics 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.
