A note from us

We have been building tools and systems for ourselves for the past two years. The fact that this repo is small and has few stars is not because it is new. It is because we only just decided to share what we have built. It is not a fresh experiment, it is a long story with a recent commit.

We love building things and sharing them. We do not love social media tactics, growth hacks, or chasing stars and followers. So this repo is small. The code is real, it gets used, issues get answered. Judge for yourself.

If it helps you, sharing, testing, and feedback help us. If it could be better, an issue is more useful. If you build something with it, tell us at hello@studiomeyer.io. That genuinely makes our day.

From a small studio in Palma de Mallorca.

With Claude Code (stdio)

{
  "mcpServers": {
    "video": {
      "command": "npx",
      "args": ["-y", "mcp-video"]
    }
  }
}

With npx

npx mcp-video

git clone https://github.com/studiomeyer-io/mcp-video.git
cd mcp-video
npm install
npx playwright install chromium
npm run build
npm start

HTTP mode

# Start as HTTP microservice
npx mcp-video --http --port=9847

# Or via environment variables
MCP_HTTP=1 MCP_PORT=9847 npx mcp-video

Narrated explainer	video_speech → video_color	AI voiceover + cinematic color grade
Before/after comparison	video_screenshot → video_edit	Smart element screenshots + PiP composition
Automated QA	video_record + video_screenshot	Record user flows + screenshot specific elements

Usage Examples

Record a website

Use video_record with type "cinema" to record https://example.com
with a smooth scroll and hover over the navbar.

Create a narrated explainer video

Use video_speech with type "narrated" to create a narrated video of
https://example.com with these segments:
1. "Welcome to our homepage" — pause on hero section
2. "Check out our features" — scroll to features
3. "Get started today" — hover over CTA button

Auto-caption a video

Use video_text with type "caption" to add auto-generated captions
to /path/to/video.mp4

Export for social media

Use video_compose with type "social-all" to convert
/path/to/video.mp4 to all social media formats.

Smart screenshot

Use video_screenshot with type "capture" to screenshot the chat widget
and pricing section on https://example.com
