# Pagecast

> MCP server that turns AI browser interactions into polished product demos — GIF or MP4 with auto-zoom effects.

## Docs

- [GitHub](https://github.com/mcpware/pagecast)
- [npm](https://www.npmjs.com/package/@mcpware/pagecast)

## Quick Start

```bash
# Add to Claude Code
claude mcp add pagecast -- npx -y @mcpware/pagecast

# First time: install browser
npx playwright install chromium
```

Requires Node.js >= 20 and ffmpeg.

## What It Does

- Records a browser page via Playwright and exports as GIF or MP4
- **Tooltip mode** (`smart_export`): full viewport + magnified tooltip inset on each interaction
- **Cinematic mode** (`cinematic_export`): camera crops and pans to follow interactions
- **Plain mode** (`convert_to_gif` / `convert_to_mp4`): standard screen recording, no zoom
- Platform presets: say "for GitHub README" or "for TikTok" and it picks the right size/format
- Injects cursor highlight (red dot) and click ripple automatically
- Two-pass ffmpeg palette optimization for small, high-quality GIFs

## MCP Tools

- `record_page` — open URL, start recording (auto-injects cursor overlay)
- `interact_page` — click, type, hover, scroll, press keys, select, navigate, waitForSelector
- `stop_recording` — stop and save .webm + timeline.json
- `smart_export` — tooltip overlay export (magnified close-up on each interaction)
- `cinematic_export` — cinematic crop-pan export (camera follows the action)
- `convert_to_gif` — WebM to optimized GIF
- `convert_to_mp4` — WebM to MP4 (H.264)
- `record_and_export` — all-in-one: record + auto-export based on platform
- `list_recordings` — list all .webm, .gif, .mp4 files in output directory

## Platform Presets

| Platform | Size | Format |
|----------|------|--------|
| `github` / `readme` | 1280x720 | GIF |
| `youtube` / `twitter` | 1280x720 | MP4 |
| `reels` / `tiktok` / `shorts` | 1080x1920 | MP4 |
| `instagram` / `linkedin` | 1080x1080 | MP4 |
