Type or paste Markdown (# headings, **bold**, - lists, tables) and save it as a Word, PowerPoint, OpenDocument, web page or e-book file.
GUI Hub gives your assistant these 2 tools. Install it once (below) and ask in plain words.
| MCP tool | What it does | Inputs |
|---|---|---|
| pandoc_convert | Convert documents between formats with Pandoc (input format is detected from the file extension: .docx .md .html .epub .odt .rtf .txt .tex). Several inputs are concatenated in order. Use to='gfm' to turn Word/HTML into Markdown for reading or editing. | inputs* array to string toc boolean out* string |
| pandoc_write | Create a real document file on the user's computer from Markdown you write (pass the full text in `text`): Word (.docx), PowerPoint (.pptx — each `## heading` starts a new slide), OpenDocument (.odt), HTML, EPUB or RTF. The `out` file extension should match `to`. | text* string to string toc boolean out* string |
