Why delete_mailing_list needs a policy

This tool irreversibly removes a mailing list and associated data from the Qualtrics platform. Deletion is a one-way operation that cannot be undone. The blast radius includes loss of contact lists, distribution history, and potential disruption to survey campaigns relying on that list. This is more severe than Write (which is reversible) and qualifies as Destructive under the categorization rules.

From the tool's definition Tool name 'delete_mailing_list' with description 'Delete a mailing list' indicates irreversible removal of data.

POLICY

How to control delete_mailing_list

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_mailing_list:

policy.json

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

delete_mailing_list 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.
