WHAT IT DOES

What create_presentation does on Keynote MCP Server

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

WHY IT NEEDS A POLICY

Why create_presentation needs a policy

Creating a new presentation is a Write operation—it creates new data (a presentation file) that can be subsequently modified or deleted, with no permanent or irreversible consequences. The blast radius is minimal: the worst outcome is an unwanted presentation file created, which can be easily removed.

From the tool's definition Tool description states it 'Creates a new blank Keynote presentation', which is a creation operation that modifies the filesystem/application state by adding a new reversible resource.
