Majin Slide MCP

A Model Context Protocol (MCP) server for generating markdown slide presentations with AI-powered prompts. This server helps you create professional presentations by generating structured prompts and saving them as markdown files.

Marpのプレビューとエクスポート（Cursor / VS Code）

生成したMarp形式（Markdown）のスライドは、CursorやVS Codeで拡張機能「Marp for VS Code」をインストールすると、エディタ上でプレビュー表示でき、さらにPowerPoint（.pptx）/ PDF / HTMLとしてエクスポートできます。

• Cursor / VS Code の拡張機能から「Marp for VS Code」をインストール
• .md ファイルを開き、コマンドパレットで「Marp: Open Preview」を実行してプレビュー
• エクスポートは「Marp: Export」から選択（PowerPoint / PDF / HTML）

Key Features

• AI-Powered Slide Generation: Generate comprehensive markdown slide prompts based on your specifications
• Customizable Presentations: Control style, audience, language, and content preferences
• File Creation: Save generated slides directly to markdown files
• Template Library: Access various presentation templates and formats
• Provider-Agnostic: Works with any LLM that supports MCP

Requirements

• Node.js 18 or newer
• VS Code, Cursor, Windsurf, Claude Desktop, or any other MCP client
• No API keys required (the server generates prompts, not the actual content)

Getting Started

First, install the MCP server with your client.

Standard config works in most tools:

{
  "mcpServers": {
    "majin-slide": {
      "command": "npx",
      "args": ["@taiyokimura/majin-slide-mcp@latest"]
    }
  }
}

Install in VS Code
Install in VS Code Insiders

Quick usage (利用手順)

# npx（非対話フラグ付き）
claude mcp add majin-slide -s user -- npx -y @taiyokimura/majin-slide-mcp@latest

# グローバルインストール
npm i -g @taiyokimura/majin-slide-mcp \
  && claude mcp add majin-slide -s user -- majin-slide-mcp

claude mcp add majin-slide -s user -- npx @taiyokimura/majin-slide-mcp@latest

claude mcp remove majin-slide

code --add-mcp '{"name":"majin-slide","command":"npx","args":["@taiyokimura/majin-slide-mcp@latest"]}'

{
  "$schema": "https://opencode.ai/config.json",
  "mcp": {
    "majin-slide": {
      "type": "local",
      "command": [
        "npx",
        "@taiyokimura/majin-slide-mcp@latest"
      ],
      "enabled": true
    }
  }
}

Available Tools

1. generate_slide_prompt

Generate a comprehensive Marp-oriented prompt. Only topic is required; the server embeds it into the prompt.

Parameters:

• topic (required): The main topic of the presentation

Example:

{
  "topic": "Introduction to Machine Learning"
}

2. create_slide_file

Save the generated slide content to a markdown file.

Parameters:

• filename (required): Name of the file (without extension)
• content (required): The markdown content
• output_dir: Directory path (default: current directory)

Example:

{
  "filename": "ml-introduction",
  "content": "# Introduction to Machine Learning\n\n---\n\n## What is ML?\n...",
  "output_dir": "./presentations"
}

Workflow Example

1. Generate a slide prompt:

   Use the generate_slide_prompt tool with topic "Climate Change Solutions"
   

2. Use the prompt with your AI: Copy the generated prompt and use it with your preferred AI model to create the actual slide content.

3. Save the slides:

   Use the create_slide_file tool to save the generated markdown
   

4. Convert to presentation: Use tools like Marp, reveal.js, or Slidev to convert the markdown to a presentation.

Supported Presentation Tools

The generated markdown files are compatible with:

• Marp - Markdown Presentation Ecosystem
• reveal.js - HTML presentation framework
• Slidev - Presentation slides for developers
• DeckDeckGo - Web presentations
• Obsidian Slides - If you use Obsidian
• Any markdown-to-HTML converter

Tips for Best Results

1. Be specific with your topic - The more detailed your topic, the better the prompt
2. Match style to audience - Use "academic" for research, "casual" for informal talks
3. Language support - Specify any language for international presentations
4. Code examples - Enable for technical presentations
5. Image placeholders - Keep enabled for visual presentations
