WHAT IT DOES

What email_with_tracking does on Brevo MCP Server

AI agents invoke email_with_tracking to trigger actions in Brevo MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why email_with_tracking needs a policy

Sending an email is an external operation with real-world side effects (messages delivered to recipients). It is not merely writing data to a database — it triggers communication to third parties. This falls under Execute. Severity is high because a misused agent could send emails to large numbers of recipients, cause spam, phishing, or reputational damage via the marketing platform's sending infrastructure.
