Sequel Box for Windows
AI agents connect to the desktop app only, not the browser editor. Use the installer version. The portable file is slow to start as an MCP server and its path can change.
Ask an AI agent.
Get the video.
Connect Claude, Cursor or any MCP-compatible agent to the Sequel Box desktop app. Describe the video you want, and the agent creates it and exports the MP4.
What you need.
Three things.
An MCP-compatible agent
Claude Desktop, Claude Code, Cursor, or any other app that supports MCP servers.
Node.js 18 or newer
Only for Claude Code and the shorter config. The default config uses Sequel Box itself as the runtime, so Node.js isn’t needed.
Connect in four steps.
Two minutes.
Open the menu
In the Sequel Box desktop app, click the logo (top-left) and choose Connect AI agent…
Turn on access
Switch AI agent access on. It is off by default, and nothing can control the editor while it is off.
Add it to your AI app
Pick Claude Desktop, Claude Code or Cursor / other in that window and follow the steps below.
Restart and ask
Fully quit and reopen your AI app, then ask it to make a video.
Setup for your AI app.
Pick one.
Claude Desktop
One click
Open the Claude Desktop tab and click Connect Claude Desktop automatically. Sequel Box adds itself to Claude’s settings, keeps a backup and leaves your other servers alone.
- Click the button.
- Fully quit Claude Desktop (right-click its tray icon, Quit).
- Open it again.
By hand: Settings, Developer, Edit Config, then paste the block. Your paths will differ.
{
"mcpServers": {
"sequel-box": {
"command": "C:\\Users\\you\\AppData\\Local\\Programs\\Sequel Box\\SequelBox.exe",
"args": ["C:\\Users\\you\\AppData\\Roaming\\Sequel Box\\mcp\\server.mjs"],
"env": { "ELECTRON_RUN_AS_NODE": "1" }
}
}
}Claude Code
One command
Run this once in a terminal, using the path shown in the Sequel Box window. Needs Node.js 18 or newer.
claude mcp add sequel-box -- node "C:\Users\you\AppData\Roaming\Sequel Box\mcp\server.mjs"Cursor / other
Paste the settings
Add the block from the Cursor / other tab to the app’s MCP settings, then restart it. It’s the same block as for Claude Desktop. With Node.js installed you can use the shorter version on the right instead.
{
"mcpServers": {
"sequel-box": {
"command": "node",
"args": ["C:\\Users\\you\\AppData\\Roaming\\Sequel Box\\mcp\\server.mjs"]
}
}
}Then try asking.
Plain language.
Create a 1080×1920 video with the title “Summer Sale” in big yellow text, add a whoosh sound at 0 seconds, and export it.
Bring your own assets
Give the agent your real logo, product image or clips. It uses them instead of drawing substitutes.
Name the style
Say the brand colors and the look, for example “dark premium tech, blue accent, cinematic”.
It checks its work
The agent follows design rules (safe zones, no overlapping text, no dead first second) and previews a frame before it exports.
What the agent can do.
23 tools.

Looks that feel designed
Gradient fills, soft shadows, premium text styles (gold, chrome, fire, neon…), 3D animation and whole-frame effects: bloom, film grain, vignette, light leaks. Exports MP4 at 24, 30 or 60 fps.
Private by design.
Your computer only.
Local only
The connection uses localhost with a random access token, created each time you switch agent access on. Nothing goes to the internet.
Off by default
A green “AI agent editing…” badge shows while an agent is working, and every edit is a normal undo step (Ctrl+Z).
Limited file access
The agent only reads media files at paths it names. It exports .mp4 files only inside your user folder, and never overwrites unless asked.
Troubleshooting.
Quick fixes.
“Sequel Box is not connected”
The app is closed, or AI agent access is off. Open Sequel Box and switch access on.
“token changed”
The app restarted. Restart your AI app, or switch agent access off and on.
“No project is open”
Ask the agent to start one, and it will call new_project.
Nothing happens after setup
Fully quit your AI app (for Claude Desktop, right-click its tray icon and choose Quit) and open it again.
Still stuck? Run node server.mjs --selftest from the mcp folder in Sequel Box’s data folder to see whether the app is reachable, or contact us.
Questions.
Answered.
What is the Sequel Box AI agent (MCP) feature?
MCP (Model Context Protocol) lets an AI app control Sequel Box. You describe a video, and the agent creates the project in the editor and exports it as an MP4.
Which AI apps can connect?
Claude Desktop, Claude Code, Cursor, or any other MCP-compatible agent. Claude Desktop can be set up with one click from inside Sequel Box.
Does it work in the browser version?
No. AI agents can only connect to the Sequel Box desktop app for Windows. The installer version is recommended.
Is agent access on by default?
No. It is off until you switch it on in Connect AI agent…, and nothing can control the editor while it is off.
Does anything go to the internet?
No. The connection runs on your own computer. Sequel Box listens on localhost only, with a random access token created each time you switch agent access on.
Do I need to install Node.js?
Not for Claude Desktop or Cursor with the config Sequel Box shows you, because the app itself is used as the runtime. Claude Code and the shorter config need Node.js 18 or newer.
Can I undo what the agent does?
Yes. Every edit is a normal undo step, so press Ctrl+Z. A green “AI agent editing…” badge shows while an agent is working.
Where does the exported video go?
If the agent doesn’t pick a path, the MP4 is saved in your Videos/SequelBox folder. Exports only write .mp4 files inside your user folder and don’t overwrite a file unless asked.
Watch it happen.
One sentence in.
Make a vertical video: the title “Summer Sale” in big yellow text, a whoosh at 0 seconds, then export it.
Done. Saved to Videos/SequelBox/summer-sale.mp4
