WHAT IT DOES

What close_presentation does on Keynote MCP Server

AI agents use close_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 close_presentation needs a policy

This tool modifies the state of the application by closing an open presentation, but does not delete files, corrupt data, or execute arbitrary operations. It's a stateful operation comparable to closing a document window—the underlying file remains intact and can be reopened. This fits the Write category (reversible state change) rather than Destructive (which would be permanent data loss).

From the tool's definition Closes the frontmost Keynote presentation. The description indicates it terminates/closes a document state without deleting underlying data (the file persists). This is a reversible modification to the application state.
