This is an Execute category tool because it triggers operations whose effects depend on which journey is targeted and the current state of customer data. From the tool's own definition: "Tool name 'trigger_customer_journey' indicates execution of a workflow or automation within Mailchimp. The server context (Mailchimp MCP) shows this is part of email/marketing automation platform." ## Use case AI agents invoke trigger_customer_journey to trigger actions in Mailchimp MCP.
