An MCP server for creating and editing Marp presentations with AI assistance.
This MCP server allows LLMs to edit Markdown files according to a specified layout, supporting the built-in Marp themes (default, Gaia, Uncover) and a rich set of academic and professional presentation styles.

## ⚙️ Setup

### Claude Code

**Option 1 — CLI, user scope** (recommended):

```bash
claude mcp add marp-mcp -- npx -y @masaki39/marp-mcp@latest
```

**Option 2 — CLI, project scope** (shareable with team via `.mcp.json`):

```bash
claude mcp add --scope project marp-mcp -- npx -y @masaki39/marp-mcp@latest
```

**Option 3 — Manual config** (`~/.claude/settings.json` or `.mcp.json`):

```json
{
  "mcpServers": {
    "marp-mcp": {
      "command": "npx",
      "args": ["-y", "@masaki39/marp-mcp@latest"]
    }
  }
}
```

### Other MCP clients

```json
{
  "mcpServers": {
    "marp-mcp": {
      "command": "npx",
      "args": ["-y", "@masaki39/marp-mcp@latest"]
    }
  }
}
```

### Setting server default theme/style

Use `-t` / `--theme` and `-s` / `--style` args to set the server-wide default. Choose from themes: `default`, `gaia`, `uncover`. Styles: `default`, `rich`, `minimal`, `dark`, `corporate`, `academic`, `tech`:

```json
{
  "mcpServers": {
    "marp-mcp": {
      "command": "npx",
      "args": ["-y", "@masaki39/marp-mcp@latest", "-t", "default", "-s", "rich"]
    }
  }
}
```

Omitting these flags defaults to `default` theme and `default` style.

### External styles via marp-cli config

If a marp-cli configuration file (`.marprc.{yml,yaml,json,js,cjs,mjs}`, `marp.config.{js,cjs,mjs}`, or a `marp` field in `package.json`) is found anywhere up the directory tree at server start, every CSS file listed under its `themeSet` field is registered as an MCP style. The style name is read from the file's `/* @theme NAME */` directive (lowercased). External entries reuse the active theme's layouts, so all existing tools work unchanged.

```yaml
# .marprc.yml
themeSet:
  - ./themes/sample.css
```

```css
/* themes/sample.css */
/* @theme sample */
section { background: #fff; }
```

`sample` is then a valid value for `-s` and shows up in `list_themes_and_styles` with `"external": true` and the absolute CSS path under `source`. Built-in style names are protected; any external collision is logged and skipped.

## 🛠️ Tools

| Tool | Description |
|------|-------------|
| `list_themes_and_styles` | List all available themes and styles; shows current server defaults |
| `list_layouts` | List available slide layouts for a theme/style combination |
| `create_presentation` | Create a new presentation with frontmatter and title slide in one step |
| `manage_slide` | Insert, replace, delete, or move slides using slide IDs (ID-based operations) |
| `batch_manage_slides` | Apply multiple slide operations in one call (single file read/write) |
| `set_frontmatter` | Ensure `marp`, `theme`, `header`, and `paginate` frontmatter fields are present |
| `read_slide` | Read slide content by ID or list all slides with their IDs and positions |
| `generate_slide_ids` | Generate stable UUIDs for every slide (safe to re-run) |
| `export_slide` | Export to HTML, PDF, or PPTX using marp-cli |
| `generate_agenda` | Auto-generate an agenda slide; adds numbered icons to section slides for view-transition morphing (HTML only) |
| `add_image_transition` | Insert a full-screen background image slide before a target slide and tag images for view-transition morphing (HTML only) |

### Per-call theme/style override

`list_layouts`, `manage_slide`, and `set_frontmatter` accept optional `theme` and `style` parameters to override the server default for a single call. This lets one server instance handle all theme/style combinations without restarting:

```json
{ "theme": "gaia", "style": "rich" }
```

Omit either parameter to fall back to the server default.

## 💡 Tips

### Adjusting font size

Add an inline style to any slide to override the font size for the whole presentation:

```html
section { font-size: 1em; }
```

The `academic` style sets `font-size: 0.95em` by default.

### Image morphing transitions (HTML only)

Use `generate_agenda` and `add_image_transition` to enable CSS View Transition morphing effects:

- `generate_agenda` — scans section slides, inserts an agenda with numbered icons, and adds matching icons to each section slide so the icon morphs between agenda and section views.
- `add_image_transition` — inserts a full-screen background slide before an image slide and tags both with matching `view-transition-name` so the image appears to zoom in as you advance.
