Public Discovery

mcp-video is an MCP server, Python library, and CLI for agentic video editing. It helps AI agents and automation scripts inspect, trim, merge, subtitle, resize, transcode, analyze, and generate video with FFmpeg and code-driven creation workflows.

What is mcp-video?

An open-source video editing server built on the Model Context Protocol (MCP). It gives AI agents, developers, and video creators the ability to programmatically edit and create video files.

Two modes:

1. Edit existing video with FFmpeg — trim, merge, overlay text, add audio, apply filters, stabilize, detect scenes, transcribe, and more.
2. Create new video from code with Hyperframes (HTML-native, Apache 2.0) — scaffold compositions, preview live, render to MP4, then post-process.

Three interfaces:

Interface	Best For	Example
MCP Server	AI agents (Claude Code, Cursor)	"Trim this video and add a title"
Python Client	Scripts, automation, pipelines	editor.trim("v.mp4", start="0:30", duration="15")
CLI	Shell scripts, quick ops, humans	mcp-video trim video.mp4 -s 0:30 -d 15

---

Installation

Prerequisites: FFmpeg must be installed. For Hyperframes features, you also need Node.js 22+.

# macOS
brew install ffmpeg

# Ubuntu/Debian
sudo apt install ffmpeg

Install:

pip install mcp-video
# or run without installing:
uvx mcp-video

Verify your setup:

mcp-video doctor
mcp-video doctor --json

Quick Start

As an MCP Server (for AI agents)

Claude Code:

claude mcp add mcp-video -- uvx mcp-video

Claude Desktop:

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

Cursor:

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

Then just ask your agent: "Trim this video from 0:30 to 1:00, add a title card, and resize for TikTok."

As a Python Library

from mcp_video import Client

editor = Client()

info = editor.info("interview.mp4")
clip = editor.trim("interview.mp4", start="00:02:15", duration="00:00:30")
video = editor.merge(clips=["intro.mp4", clip.output_path, "outro.mp4"])
video = editor.add_text(video.output_path, text="EPISODE 42", position="top-center", size=48)
result = editor.resize(video.output_path, aspect_ratio="9:16")

Agent-safe Python workflow

For autonomous agents, prefer inspection, pipeline chaining, and a release checkpoint:

from mcp_video import Client

client = Client()
print(client.inspect("create_from_images"))  # Real params, aliases, return type

result = client.pipeline(
    [
        {"op": "create_from_images", "images": frames, "fps": 30},
        {"op": "effect_glow", "intensity": 0.2},  # safe capped default
        {"op": "add_audio", "audio_path": "soundtrack.wav", "mix": True},
        {"op": "export", "quality": "high"},
    ],
    output_path="final.mp4",
)

checkpoint = client.release_checkpoint(result.output_path)
print(checkpoint["thumbnail"], checkpoint["storyboard"])

Agent contract:

• Media-producing client calls return EditResult with .output_path.
• Analysis/discovery calls return typed reports or dictionaries.
• Client.inspect(name) exposes parameters, aliases, category, and return type.
• Raw unexpected-keyword errors are converted into actionable MCPVideoError guidance.
• Do not publish agent-generated video without assert_quality() or release_checkpoint() plus human visual/audio inspection.

As a CLI Tool

mcp-video info video.mp4
mcp-video trim video.mp4 -s 00:02:15 -d 30
mcp-video convert video.mp4 -f webm -q high
mcp-video template tiktok video.mp4 --caption "Check this out!"

Hyperframes Integration

Create videos programmatically with Hyperframes — an HTML-native framework for video.

1. Init project       -> hyperframes_init
2. Add blocks         -> hyperframes_add_block
3. Preview live       -> hyperframes_preview
4. Render             -> hyperframes_render
5. Post-process       -> hyperframes_to_mcpvideo

See Hyperframes docs and the Python client reference.

Timeline DSL

For complex multi-track edits, describe everything in a single JSON object:

editor.edit({
    "width": 1080,
    "height": 1920,
    "tracks": [
        {
            "type": "video",
            "clips": [
                {"source": "intro.mp4", "start": 0, "duration": 5},
                {"source": "main.mp4", "start": 5, "trim_start": 10, "duration": 30},
                {"source": "outro.mp4", "start": 35, "duration": 10},
            ],
            "transitions": [
