Check whether the lo-mcp LibreOffice extension is reachable.

Call this first. If not connected, LibreOffice needs to be running with the lo-mcp extension's server started (lo-mcp menu > Start Server).

Create a new, blank Writer document. Returns a doc_id for later calls.

Open an existing document from disk. Returns a doc_id.

List documents currently open via lo-mcp, with their doc_id and modified state.

Read the full text content of a Writer document.

Append text at the end of a Writer document.

break_before controls what precedes the text: "none" (default, keeps typing in the current paragraph), "line" (soft line break, same paragraph), "paragraph" (starts a new paragraph), or "page" (starts a new paragraph on a new page).

bold/italic/underline apply direct character formatting to just the text being inserted. style is a paragraph style name (e.g. "Heading 1", "Title") applied to the paragraph the text lands in; char_style is a character style name (e.g. "Emphasis", "Strong Emphasis") applied to just the inserted run. Use list_styles to see what's actually available in a given document rather than guessing names.

Apply a paragraph style (e.g. "Heading 1", "Title") to an existing paragraph.

Defaults to the last paragraph if paragraph_index is omitted. Index is 0-based (negative indices count from the end, Python-style) and counts paragraphs only — tables don't count.

Read a paragraph's style name and break type. Defaults to the last paragraph.

paragraph_index is 0-based; negative indices count from the end, Python-style.

List style names available in a document for a given style family.

family is one of "ParagraphStyles" (default), "CharacterStyles", "PageStyles", "FrameStyles", "NumberingStyles". Use this before calling insert_text(style=...)/char_style=.../set_paragraph_style to find valid names instead of guessing — built-in style sets vary slightly by LibreOffice version and locale, and documents can also define custom styles.

Insert a table at the end of the document. Supports up to 26 columns.

data, if given, is a 2D list of row values written into cells (values beyond the table's rows/cols are ignored). header=True bolds row 1.

Read a table cell's text (e.g. cell="A1"). Uses the first table if table_name is omitted.

Replace all occurrences of search with replace in a document. Returns the count replaced.

Save a document in place (if it already has a location) or to a new path.

Export a document to path. Format is inferred from the extension if omitted.

Supported formats: odt, pdf, docx, doc, rtf, txt, html.

Close a document. Refuses if there are unsaved changes unless force=True.
