Remotion MCP App

An MCP App for AI-powered video creation. It combines an MCP server with an interactive widget — the model writes React/Remotion code, the server compiles it in real-time, and a live video player renders the result directly inside the chat.

Unlike a standard MCP server that only returns text, an MCP App bundles a full UI widget alongside its tools. The Remotion Player widget renders inline in any compatible client (ChatGPT, Claude, or custom apps built with mcp-use), giving the model a visual canvas it can iterate on.

How it works

This is an MCP App — an MCP server paired with a UI widget. The two pieces work together:

1. MCP Server -- exposes create_video tool + rule tools for teaching Remotion patterns
2. Widget -- a Remotion Player that renders inline in the chat, receives compiled bundles from the server

The flow:

1. The model calls create_video with React/Remotion source files
2. The server compiles the project with esbuild (sub-second)
3. The compiled bundle is sent back as structuredContent, and the widget renders it as a playable video
4. For edits, the model calls create_video again with only changed files -- the widget updates in-place with a loading overlay

Model                    MCP App (Server + Widget)
  |                          |
  |-- create_video({files}) ->|
  |                          |-- esbuild compile
  |<- structuredContent -----|
  |                          |-- Widget renders video inline
  |                          |
  |-- create_video({edits}) ->|
  |                          |-- merge + recompile
  |                          |-- Widget updates in-place

Single tool design

There is one tool: create_video. It handles both creation and editing. The files parameter is always required -- for edits, only send changed files. The server merges them with the previous session state.

Rule tools

The server includes teaching tools derived from the remotion-best-practices skill that the model can call to learn Remotion patterns:

Tool	Topic
rule_react_code	Project structure, imports, entry file contract
rule_remotion_animations	useCurrentFrame, frame-driven animation
rule_remotion_timing	interpolate, spring, Easing configs
rule_remotion_sequencing	Sequence, scene management, duration
rule_remotion_transitions	TransitionSeries, fade, slide, wipe
rule_remotion_text_animations	Typewriter effect, word highlighting
rule_remotion_trimming	Trimming with negative Sequence from

Widget (the "App" part)

The Remotion Player widget is what makes this an MCP App rather than a plain MCP server. It runs inside the chat interface and features:

• Live video playback with controls
• Animated loading state with shader gradient while the model writes code
• Editing overlay (blur + gradient) when updating an existing video
• Fullscreen mode
• Error display with compilation error details

Local development

Prerequisites

• Node.js 18+
• npm or pnpm

Setup

git clone https://github.com/mcp-use/remotion-mcp-app.git
cd remotion-mcp-app
npm install
npm run dev

The server starts at http://localhost:3000/mcp.

Connect a client

Point any MCP client at http://localhost:3000/mcp. For example with mcp-use:

{
  "mcpServers": {
    "remotion": {
      "url": "http://localhost:3000/mcp"
    }
  }
}

Build and deploy

npm run build
npm run deploy

Project structure

index.ts                     -- MCP server, tool definitions, handler
utils.ts                     -- esbuild compilation, session state, response helpers
types.ts                     -- Shared types (VideoProjectData, VideoMeta)
rules/                       -- Remotion teaching content served by rule tools
resources/remotion-player/   -- Widget source (React + Remotion Player)
  widget.tsx                 -- Main widget component
  components/
    CodeComposition.tsx      -- Bundle compiler (eval + runtime shim)

Tool schema

create_video({
  files: string,            // REQUIRED -- JSON string of {path: code}
  entryFile?: string,       // Default: "/src/Video.tsx"
  title?: string,
  durationInFrames?: number, // Default: 150
  fps?: number,             // Default: 30
  width?: number,           // Default: 1920
  height?: number,          // Default: 1080
})

The files parameter is a JSON string mapping virtual file paths to source code:

{
  "/src/Video.tsx": "import {AbsoluteFill} from \"remotion\";\nexport default function Video() { return <AbsoluteFill />; }"
}

Session behavior

• Each MCP session maintains its own project state
• Calling create_video merges new files with the previous project
• Metadata (title, fps, dimensions) carries forward unless overridden
• Sessions are capped at 250 concurrent projects with LRU eviction
