WHAT IT DOES

What custom_clone_smart_campaign does on Marketo MCP Server

AI agents invoke custom_clone_smart_campaign 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.

WHY IT NEEDS A POLICY

Why custom_clone_smart_campaign needs a policy

Cloning a smart campaign creates a new asset in Marketo (Write-level), but because it calls the Marketo REST API directly with a custom/non-native path, the actual scope of the API call is uncertain — it could trigger additional side effects such as activating campaigns or modifying lead data.

From the tool's definition 'Calls the Marketo REST API directly' and the action is 'clone_smart_campaign' — cloning a smart campaign creates a new campaign entity by executing an API call
