clone_program · Marketo MCP Server MCP: Risk & Policy

WHAT IT DOES

What clone_program does on Marketo MCP Server

AI agents use clone_program 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_program needs a policy

Cloning a program creates a new copy of an existing program, which is a reversible write operation. It does not delete or overwrite data, execute arbitrary code, or involve financial transactions. The blast radius is medium as cloning a program could create unintended duplicates or trigger associated assets.
