WHAT IT DOES

What close_presentation does on Cross-Platform PowerPoint MCP Server

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

WHY IT NEEDS A POLICY

Why close_presentation needs a policy

Closing a presentation is a reversible write-like operation—it changes the state of which presentations are open without destroying data. The presentation remains saved and can be reopened. This is less severe than operations that modify presentation content (Write category operations like add_slide, add_text_box), but represents a state modification rather than pure data retrieval.

From the tool's definition Tool name 'close_presentation' and description 'Close a presentation' indicates a state-changing operation on an open presentation resource.
