The MCP server exposes the full GroupDocs.Merger engine: every format the .NET library can merge and split — 30+ document, spreadsheet, presentation, image, and archive formats — is available to your AI agent. The canonical matrix lives in the library documentation: supported document formats.
What agents are asked for most:
- PDF — the common case: combine parts, extract a page, assemble a pack.
- DOCX / DOC — merge sections while the document is still editable, rather than converting to PDF first.
- XLSX — combine workbooks;
splitextracts by worksheet position in spreadsheet formats. - PPTX — join decks, or pull out the slides you need.
The rule that governs every merge: same format family. All PDFs, or all DOCX, or all XLSX. This is not an arbitrary restriction — combining a spreadsheet with a presentation has no meaningful result. When sources differ, convert them to a common format first with the GroupDocs.Conversion MCP server, then merge the matching set.
Unsure what you are holding? Ask — “are these all the same format, and how many pages each?” — and the agent answers via get_document_info.
