THE RISK

High Risk

Why create_email_distribution needs a policy

This tool sends emails externally to a mailing list, which is an irreversible external communication operation. It cannot be undone once emails are dispatched. The blast radius is high because misuse could send unwanted emails to an entire mailing list. It falls under Execute as it triggers an external operation (email delivery) rather than merely writing data internally.

From the tool's definition 'Send a survey via email to a mailing list' — triggers an external email operation to potentially many recipients

POLICY

How to control create_email_distribution

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 create_email_distribution:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "create_email_distribution": {
      "limits": [
        {
          "counter": "create_email_distribution_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
}

create_email_distribution stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

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.
