On this page
The MCP server exposes the full GroupDocs.Viewer engine for reading documents: every format the .NET library can open — 170+ document, spreadsheet, presentation, email, CAD, and image formats — can be rendered through render_page and inspected with get_view_info. The canonical list lives in the library documentation: supported file formats.
What changes by family:
- PDF, Word, RTF, OpenDocument text — one image per printed page, exactly as the document paginates.
- Excel, OpenDocument spreadsheets, CSV — the engine splits a sheet into pages;
get_view_infoshows how many there are before you render. - PowerPoint, OpenDocument presentations — one image per slide.
- Email (EML, MSG) — the message with its headers, rendered as a page.
- Images and CAD — rendered to PNG, which is also a simple way to let an agent see a format it cannot open itself.
The output is PNG only through MCP. The library also renders to HTML, JPG, and PDF, but those are not exposed as tools today.
