WHAT IT DOES

What approve_email_program does on Marketo MCP Server

AI agents invoke approve_email_program to trigger actions in Marketo 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.

RISK

Why approve_email_program is rated High

Approving an email program in Marketo transitions it from draft to active state, which can trigger email sends to potentially large audiences. This is an external operation with significant real-world effects (emails sent cannot be recalled), making it Execute at high severity due to the blast radius of mass email communication.

From the tool's definition 'Approve an Email Program in Marketo' — approving triggers external operations (activating/sending email campaigns to recipients)
