WHAT IT DOES

What createComponent does on AEM MCP Server

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

WHY IT NEEDS A POLICY

Why createComponent needs a policy

Creating a new component on a page in AEM is a Write operation: it adds content to the system in a reversible manner (the component can be deleted or modified later). It does not execute arbitrary code, delete irreversibly, or involve financial transactions.

From the tool's definition Tool name is 'createComponent' and description states 'Create a new component on a page' — this is a creation operation that modifies content reversibly.
