LibreOffice is a free and open-source office suite, developed by The Document Foundation, offering word processing, spreadsheets, presentations, and more as an alternative to proprietary office software.
Enables the convert_to_pdf tool to turn Office documents (docx, xlsx, pptx, odt) and HTML files into PDFs using a locally installed LibreOffice (soffice) binary, extending the server's conversion capabilities beyond images and plain text.
Gives AI assistants a full PDF toolkit — encrypting, decrypting, merging, splitting, reordering, rotating, optimizing, repairing, and converting PDFs through natural-language requests, with sandboxed file access and safe handling of damaged or password-protected files.

Why this server?
Uses headless LibreOffice to refresh field results such as tables of contents, page numbers, sequence numbers, and cross-references, and provides the bridge for live LibreOffice Writer integration.
Deterministic, LLM-first control of Word documents (.docx). An agent reads the outline, finds text by phrase, and applies edits as tracked changes and comments in one atomic batch, with a safety layer that refuses edits based on a stale read and rolls back failed batches. It works on .docx files directly, and can also drive an open document in Microsoft Word on Windows or in LibreOffice Writer.

Why this server?
Drives LibreOffice over UNO on Linux to open, measure, and fix .docx documents: reports page counts, locates strings by page, maps headings and sections with page ranges, extracts page text, formats paragraphs (keep-with-next, widow control), refreshes fields and tables of contents, and exports to PDF using LibreOffice's own pagination engine.
Enables measuring and fixing the page layout of .docx documents by driving Microsoft Word or LibreOffice, including page counts, section outlines, text search, paragraph formatting, field updates, and PDF export.

Why this server?
Serves as an automatic fallback PDF conversion backend: when Hancom Office (한글) is unavailable, the server drives LibreOffice to render the generated HWPX document into a near-accurate PDF.
Enables AI assistants to analyze the formatting of a Hancom Office (HWPX) template and generate new documents that reuse that exact styling, outputting both HWPX and PDF files. Exposes tools for template analysis, document building with automatic layout checks, and page preview rendering.
