WHY IT NEEDS A POLICY

Why custom_create_email_template2 needs a policy

This tool creates new email templates in Marketo, which is a reversible data creation operation (Write category). Severity is high because misconfigured or malicious email templates could be used for phishing, spam, or brand damage at scale. The direct REST API invocation without native MCP wrapper increases risk of unintended side effects.

From the tool's definition Tool name includes 'create' and description indicates it calls Marketo REST API directly to create email templates. The [CUSTOM] designation suggests it bypasses native abstractions and directly invokes API operations that modify marketing assets.
