clone_smart_campaign · Marketo MCP Server MCP: Risk & Policy

WHAT IT DOES

What clone_smart_campaign does on Marketo MCP Server

AI agents use clone_smart_campaign 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.

WHY IT NEEDS A POLICY

Why clone_smart_campaign needs a policy

Cloning creates a new copy of an existing smart campaign, which is a write/create operation. It does not delete or modify the original, and does not execute or trigger the campaign. The blast radius is medium since smart campaigns can affect lead processing workflows, but cloning itself is reversible (the clone can be deleted).
