Extract text content from a LibreOffice document
AI agents call read_document_text to retrieve information from LibreOffice MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves document content without side effects. It performs a query operation analogous to a fetch or get, returning existing data without altering the document or triggering external operations. The low severity reflects minimal risk even if misused by an agent, as reading text cannot damage data or cause unintended consequences.
From the tool's definition Tool name contains 'read', description states 'Extract text content' with no mention of modification, creation, or deletion capabilities.
