What create_presentation does on PPTX MCP Server

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

WHY IT NEEDS A POLICY

Why create_presentation needs a policy

This tool creates new files/data (a PowerPoint presentation) without deleting or overwriting existing data, making it a Write operation. Severity is medium because an AI agent could create numerous unwanted presentation files consuming storage or creating confusion, but the damage is reversible (files can be deleted). Confidence is high due to explicit language about creation in both name and description.

From the tool's definition Tool name 'create_presentation' and description states it will 'Create a new PowerPoint presentation from scratch,' which is a creation operation that modifies the file system by introducing new data artifacts.
