WHAT IT DOES

What pack_office_document does on PPTX MCP Server

AI agents use pack_office_document 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 pack_office_document needs a policy

This tool creates or assembles Office documents by packing directory contents, which is a write operation that produces persistent file artifacts. While not destructive in itself (it doesn't delete or overwrite existing files unless explicitly told to), it modifies the file system state and could be misused to inject malicious content into Office documents at scale if an AI agent manipulates the directory structure…

From the tool's definition Tool description states: 'Pack a directory back into an Office document (.docx, .pptx, .xlsx)'. This writes/creates Office documents from directory contents, modifying file system state irreversibly through document creation/assembly.
