OmniDocHow to Use an MCP Server with AI Assistants for Documents
Learn how to use an MCP server with an AI assistant. Connect OmniDoc, confirm its document tools appear, then translate, edit or publish a file.
If you want an AI assistant to open a PDF, translate it, or produce a Word file you can actually send, you need a way for the assistant to reach document tools. That is what an MCP server provides. Most people searching for how to use an MCP server already know roughly what it is. What they usually need is the connection set up and one task running from start to finish.
OmniDoc works as an MCP server for AI assistants such as Claude and Cursor. Once it is connected, the assistant can create and edit Word, PDF, PowerPoint and Excel files, translate files, and publish documents as web pages. This guide walks through the connection and a first task, step by step.
By the end, you will have OmniDoc connected to an assistant, confirmed that the document tools are visible to it, and run one real task. The general steps are the same across assistants, but the place where you add a server differs from product to product.
How do you use an MCP server with an AI assistant? The short answer
Add OmniDoc's MCP server to an AI assistant that supports MCP, confirm the document tools appear, then ask for one task at a time and check the file it returns.
| Your situation | What to do | Why |
|---|---|---|
| Your assistant supports MCP servers | Add OmniDoc as a server in the assistant's settings | The assistant can then call OmniDoc's document tools |
| You need a PDF or Word file translated | Ask for the translation and name bilingual or translation-only output | Layout, tables, formulas and pictures are kept |
| You need a new or edited Office file | Ask for a Word, Excel or PowerPoint file and describe the changes | OmniDoc can create and edit these formats through the assistant |
| You want to share a document online | Ask the assistant to publish the document as a web page | You get a web version of the document to share |
| Your assistant does not support MCP | Work directly in the desktop client or the web editor | MCP needs an assistant that can connect to outside servers |
Before you start
- Confirm your assistant supports MCP servers. Without MCP support, there is nowhere to connect OmniDoc. Check the assistant's own documentation for the server settings.
- Get OmniDoc's connection details for its MCP server. The assistant needs these details to reach OmniDoc's tools. Copy them exactly, because a single wrong character will stop the connection.
- Pick a short test file. A 2- to 4-page PDF with no sensitive content is enough. A small file makes it quick to check the result.
- Decide your output format before you ask. Bilingual side by side is useful for review, and translation only is useful for a clean copy. Naming the choice up front avoids guesswork.
- Plan time to check the result. Machine translation can make mistakes, so review names, numbers and key terms before you rely on the output.
Connecting OmniDoc's MCP server and running your first task, step by step
- Open your assistant's MCP server settings. Every assistant has a place to add servers, but the wording and location differ, so use its documentation if you cannot find it.
- Add OmniDoc as a new server. Enter the connection details OmniDoc gives you. The assistant uses these to reach OmniDoc's tools.
- Save the settings and restart or reload the assistant if it asks. Many assistants read their server list only at startup, so a new server may not appear until you do this.
- Ask the assistant which OmniDoc tools it can see. This confirms the connection before you start real work. If no OmniDoc tools appear, the connection has not worked yet.
- Give one clear translation request with your test file. For example, ask the assistant to translate a 3-page PDF into English as bilingual side-by-side output. Provide the file in whatever way your assistant supports.
- Try a create or edit task next. You might ask for a Word summary of a report, or for changes to the slide titles in a PowerPoint file. Describe exactly what should change, so the assistant does not have to guess.
- Ask for publishing only when you need it. For example, ask the assistant to publish a finished document as a web page and tell you where to find it. Review the page before you send it to anyone.
- Open the returned file and check it. The assistant's summary tells you what it did, but only the file itself shows whether the output is right.
Check the result
Check each output before you share it. The table below covers a common problems.
| Check | How to see it | If it's wrong |
|---|---|---|
| OmniDoc tools are visible | Ask the assistant to list the OmniDoc tools it can use | Recheck the connection details, save, and reload the assistant |
| Layout is intact | Compare the output with the original page by page | Rerun the task on the same file and ask the assistant to keep the layout |
| Terms are consistent | Search the translation for names, numbers and defined terms | Ask for a correction that lists each term and its required wording |
| Small text errors | Look at the affected paragraphs in the PDF | Fix the text in place with the PDF editor in the desktop client at download.omnidoc.top |
| Office file opens | Open the file in its own application | Ask for a corrected version and name the specific problem |
| Web page reads correctly | Open the published page and scroll through every section | Ask for a new version after you describe the changes, then publish again |
❓ FAQ
1. What if the assistant cannot see any OmniDoc tools?
Check that your assistant supports MCP servers, then recheck the connection details you entered for typos. Save the settings and restart or reload the assistant, because many assistants only read their server list at startup.
2. Can I use a scanned PDF with this setup?
Yes. Scanned PDFs are supported for translation, so you can give the assistant a scanned file in the same way as a digital one. Check the output carefully, since scanned text can be harder to read correctly.
3. Which file types can the assistant work with?
OmniDoc's translation covers PDF (digital and scanned), Word .docx, PowerPoint .pptx, Excel .xlsx, EPUB, Markdown, subtitle files (SRT and ASS), LaTeX source packages and images. For creating and editing, the assistant can work with Word, PDF, PowerPoint and Excel files.
4. Do I need MCP to use OmniDoc's document tools?
No. You can work directly in the OmniDoc desktop client or in the UniDoc web editor at app.unidoc.top. MCP is useful when you want an AI assistant to run document tasks on your behalf.
📝 Summary
Connecting an MCP server to an AI assistant comes down to adding the server, confirming its tools are visible, and then running one task at a time. Use a short test file, name the output you want, and check every returned file before you share it.
