OmniDocWhen doing PPT, choose Skill or MCP: Break it down by task.
Centering on the two kinds of tasks of doing PPT and translating PPT, this paper separates and compares what is suitable and where the deficiency is between Skill and MCP, gives the judgment basis for choosing according to the task, and explains how to access the route of MCP in OmniDoc.
- main points of this article *
-Skill is like an operation manual, which is suitable for handing over the fixed PPT specification to AI for execution, but it cannot read and write files directly. -MCP lets AI assistant call external tools to really open, modify and translate existing PPTX, which is suitable for the task of touching real documents. -just a few pages of outline or speech text, direct dialogue is enough; if the document already exists, you should take a look at the route of tools such as MCP. Either way, the translated or generated PPT should check proper nouns, numbers, and chart text before delivery.
If you are doing PPT with an AI assistant, or if you want to translate an English presentation into Chinese, you will soon come across two words: Skill and MCP. Some people on the Internet say that Skill is more suitable for PPT, while others say that MCP is the right way, and they are often more confused after reading it.
The two solve different problems. Skill is more like giving AI an operating manual telling it what steps and specifications to follow for certain tasks, while MCP allows AI to invoke external tools to actually open, modify, and save a file. When doing PPT, you may use both, or you may only need one, depending on whether your task is to "generate a set of slides from scratch" or "change existing documents" or "translate existing documents".
This article is broken down into tasks. After reading this, you should be able to decide which one you should choose, and know how to access the MCP route in OmniDoc.
# should I use Skill or MCP to do PPT? Conclusion in a word
To generate content from zero and apply a fixed style, first of all, Skill; needs to read and write PPT files directly, translate or modify existing files in batches, and use MCP methods that can call tools. The two are often used together, instruction tube specifications, tool tube files.
| your situation | Recommended practice | Reason |
|---|---|---|
| Generate a new lecture-style slide from an outline, requiring a unified style | Skill is dominant. | Page count, title writing and layout requirements can be written into instructions, and AI outputs according to specifications. |
| Modify an existing PPTX and retain the original layout | MCP tool | AI needs to actually open the file and rewrite it, which can't be done by instructions alone. |
| Translate English PPT into Chinese and English | MCP tool | Reading a file, retaining typesetting, and then outputting it is a file operation. |
| I just want the chatbot to write a few pages of outline and copywriting. | direct conversation | The task is simple, the file is not yet formed, and no additional configuration is required. |
| The team should unify a process for making PPT | Skill plus MCP | The specifications are deposited in the instructions, and the file operations are left to the tools. |
# what's going on with several practices?
Skill: specifications are written in instructions
A Skill is usually a set of instructions plus a small amount of scripts that tell AI what process to follow in a certain type of task. For example, "PPT for academic defense" can specify the total number of pages, the writing of the title of each page, and the requirements of the chart.
It is suitable for scenarios where the output specification is fixed and needs to be applied repeatedly. The drawback is that Skill itself can't read or write files on your computer for AI, it only guides ideas, and tools are needed to land. The more detailed the specification, the higher the maintenance cost.
MCP: let AI call external tools
MCP (Model Context Protocol) is a protocol that allows AI helpers to connect to external tools. After accessing the MCP service, AI can invoke the functions provided in it, such as creating or editing Word, PDF, PPT, Excel files, translating files, or publishing documents to web pages.
It is suitable for tasks that need to touch real documents. The short board is to complete the access configuration first, and the tool only does what it provides, and the style preference still needs to be made clear in the dialogue.
General chat robot plus manual copy
Many people directly ask chatbots to output outlines or text, and then paste them into PPT. In this way, the threshold is low, and a few pages are basically enough. The disadvantage is that you have to adjust the typesetting yourself, the longer the document, the more troublesome it is, and there is no link to check against the original text.
AI function of online conversion between website and desktop office software
Some online conversion sites only do format conversion or simple generation. Before uploading a file, you should read the privacy policy and confirm whether the file will be retained. The built-in AI function of desktop office software depends on what operations the software itself supports. They can be used as independent choices, but the idea is different from "have the AI helper invoke the tool as required."
# Core comparison
| Practice | Can you read and write existing documents? | Appropriate file length | Whether the content leaves this machine or not | Check cost |
|---|---|---|---|---|
| Skill is used alone | No, just come up with ideas and norms | Generated from zero, unlimited length | Depends on the AI assistant used | You need to check whether the output conforms to the specification |
| MCP tool | Yes, operate according to the functions provided by the tool | Suitable for complete sets of documents, such as dozens of pages of PPTX | Depending on the service connected, you need to see the privacy instructions. | From medium to high, check the content and format of the file |
| Copy chat content manually | Can't. | A few pages are more appropriate, the longer the more troublesome | Depends on the chat tool used | Gao, typesetting and content have to be checked by yourself. |
| Online conversion website | Usually only do format conversion | Depending on the restrictions of the website | You usually need to upload files, you need to see the privacy policy. | From low to medium, mainly check the conversion results |
# which method is suitable for you?
if all you want is a speech framework
State the topic and the number of pages directly in the dialogue, and supplement the Skill-style specification if necessary. It is easier to use a few pages of outline in this way.
if you already have a copy of PPTX to modify
Select a MCP tool that can read and write PPTX, and let AI make changes based on the original file. After modification, open it to check whether the layout is misplaced.
if you want to translate the English presentation into Chinese
Use the MCP translation function to process the whole document and choose Chinese-English or translation-only. The translation results should be page by page to check the proper nouns, numbers and the text in the chart.
if your team wants to unify the PPT process
The page number, title, color matching and other specifications are written as Skill, and the reading, generation and translation of the file are handed over to the MCP tool. This kind of regulation and enforcement have their own ownership.
if there are only a few pages and there is no hurry
Use chat robot to write text, typesetting in PPT, the cost is low. If there is more content, then consider the tool route.

# frequently asked questions (FAQ)
1. Can Skill and MCP be used together?
Yes. Skill is responsible for prescribing practices and styles, while MCP is responsible for actually reading and writing documents. The two are divided into different tasks and often go together.
2. How to choose to be the MCP of PPT?
First see if it can open and save your file format (such as PPTX), then see if it can retain the original layout, and finally check the privacy instructions to confirm how the file is processed.
3. Can the translated PPT be sent directly to others?
It is not recommended to send it directly. Machine translation may make mistakes, especially the words in proper nouns, numbers and charts, which should be checked page by page before sending.
4. Can I configure MCP if I don't know the technology?
Generally, you can fill in the service information according to the setting interface of the AI assistant. The specific steps are based on the access instructions of the assistant and OmniDoc.
# Summary
Whether to choose Skill or MCP for PPT depends on whether the task generates content or deals with existing files: the former is specification-based, while the latter requires tools to land. The two are often matched, command tube style, tool tube files, and remember to check the contents before delivery.
