WHAT IT DOES

What custom_unapprove_email_template does on Marketo MCP Server

AI agents use custom_unapprove_email_template to create or update resources in Marketo MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Marketo MCP Server environment.

RISK

Why custom_unapprove_email_template is rated Medium

The tool name suggests it unapproves an email template in Marketo, which is a reversible state change (toggling approval status). This falls under Write category as it modifies the approval state of an asset without deleting it. The description is largely uninformative beyond indicating it calls the Marketo REST API directly, which lowers confidence.

From the tool's definition 'custom_unapprove_email_template' and '[CUSTOM] Calls the Marketo REST API directly (not Adobe's native MCP)'
