WHAT IT DOES

What document_create does on LibreOffice MCP Tools

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

WHY IT NEEDS A POLICY

Why document_create needs a policy

This tool creates new, empty documents in standard Office formats (DOCX, XLSX, PPTX) without modifying existing data or executing arbitrary code. Creation of blank documents is a reversible write operation with minimal blast radius—the worst case is cluttering the filesystem with empty files. It does not delete, execute code, transfer funds, or modify existing documents.

From the tool's definition Tool name 'document_create' and description states it will 'Create a new empty document and open it' with support for multiple document types (writer, calc, impress). The action is explicitly creational.
