MCP Transcribe Online Videos

MCP Transcribe Online Videos

A FastMCP server that allows LLMs to access and transcribe online videos from YouTube and Bilibili using Replicate and 0x0.st for temporary file hosting.

Features

• Transcribe YouTube/ Bilibili videos with timestamped output
• Automatic audio extraction and format conversion
• Cloud-based transcription via WhisperX models
• Temporary file hosting for large files

Installation

Prerequisites

• Python 3.12+
• Conda (recommended for environment management)

Setting Up the Environment

# Create and activate a conda environment
conda create --name mcp_transcribe_online_vids python=3.12
conda activate mcp_transcribe_online_vids

# Install required system packages
conda install conda-forge::uv conda-forge::ffmpeg conda-forge::sqlite

# Install Python dependencies
uv pip install -r requirements.txt

Configuration

1. Copy the .env.template file to .env:

   cp .env.template .env
   

2. Edit the .env file with your credentials:

   • REPLICATE_API_TOKEN: Get from Replicate's API key page
   • ZERO_X_URL: URL for the 0x0.st instance (default: public instance)
   • TEMP_FILE_PATH: Directory for temporary files
   • LOCAL_FILE_SIZE_LIMIT: Maximum file size in MB for direct API uploads

Usage

Starting the Server

python main.py

Available Tools

• get_youtube_transcript(url): Transcribe a YouTube video
• get_bilibili_transcript(url): Transcribe a Bilibili video

Example

from fastmcp import MCPClient
import asyncio

async def get_transcript():
    client = MCPClient("http://localhost:8000")
    async with client:
        transcript = await client.call_tool("get_youtube_transcript",
            {"url": "https://www.youtube.com/watch?v=dQw********"})
        print(transcript)

# Run the async function
asyncio.run(get_transcript())

Deployment Options

For deploying the server in production environments, see FastMCP transport options.

To customize the transport, modify the mcp.run() call in main.py.

Self-hosting File Storage

It's highly recommended to host your own instance of 0x0.st for file storage. Follow the hosting instructions to set up your own instance.

Roadmap

• Add tools to retrieve video metadata (title, date, description)
• Add YAML configuration for deployment settings
• Add more file hosting options (Google Cloud, S3)
• Complete local transcription option using WhisperX
• Support for other media sources e.g. Spotify podcasts
