THE RISK

Why remove_contact needs a policy

This tool performs an irreversible deletion operation on contact data. While the blast radius is somewhat limited to a single contact record rather than bulk data, removal of contacts from mailing lists is a destructive action that cannot be automatically reversed.

From the tool's definition Tool name 'remove_contact' combined with description 'Remove a contact from a mailing list' indicates irreversible deletion of contact data. The action cannot be easily undone and permanently removes a record.

POLICY

How to control remove_contact

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 remove_contact:

policy.json

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

remove_contact 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.
