Overview

AI-generated overview

DemoStudio lets an AI assistant generate short-form video ads for Instagram Reels, TikTok and YouTube Shorts from a text brief, then check render status and set

What you can do
Generate a rendered short-form video ad from a text brief, with optional product URL crawling, music mood, subtitles and voiceover gender choices. Check build progress for a project and retrieve the exported video URL. List the available scene types and Remotion templates. Create a recurring schedule so videos are generated automatically on a daily, weekly, biweekly or monthly cadence.
When to use it
Use it when you want an assistant to turn a product brief into a social video ad without leaving the conversation, or to set up recurring automated video generation for a brand.
Requirements
Runs locally over stdio via the npm package, so Node.js 18+ is needed. A DemoStudio API key is required in the DEMOSTUDIO_API_KEY environment variable. Network access to the DemoStudio service is implied.
Before you install
The server needs a DemoStudio API key, which is a billable credential. Usage is credit-based: scene generation, video export and automated runs each consume credits, so generating videos spends money on the account. Scheduled runs generate videos repeatedly and consume credits each time. A product URL supplied to the tools is crawled by the service.

Installation

In SourceWeft

  1. Open DemoStudio in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Other MCP clients

Follow the launch instructions in the repository.

Maintainer guide — publishing updates

1. Make code changes in src/index.ts

2. Bump the version

bash
npm version patch   # 0.1.2 → 0.1.3  (bug fix / small change)npm version minor   # 0.1.2 → 0.2.0  (new tool or renamed tool)npm version major   # 0.1.2 → 1.0.0  (breaking change)

3. Publish to npm

bash
npm publish --access public

The prepublishOnly script runs tsc automatically before publishing.

4. Update server.json — bump both version fields

json
{  "version": "0.1.3",          ← top-level version  "packages": [{    "version": "0.1.3"         ← must match npm version  }]}

5. Re-authenticate and publish to MCP registry

The registry JWT expires after ~1 hour. Always re-login before publishing.

bash
# Download the publisher binary (if not already on PATH)curl -L "https://github.com/modelcontextprotocol/registry/releases/latest/download/mcp-publisher_$(uname -s | tr '[:upper:]' '[:lower:]')_$(uname -m | sed 's/x86_64/amd64/;s/aarch64/arm64/').tar.gz" | tar xz mcp-publisher
# Login via GitHub device flow./mcp-publisher login github# → go to https://github.com/login/device and enter the printed code
# Publish./mcp-publisher publish server.json

6. Push to GitHub

bash
git add -Agit commit -m "chore: bump to vX.Y.Z — <what changed>"git push origin main

Score

40% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
