Whats Trending On Social Media

This MCP server fetches trending data from YouTube, TikTok, and Instagram Reels by combining scraping techniques with API access. It is designed to run with FastMCP and exposes a set of practical tools you can use from a local CLI or by starting the server directly. Use it to surface current trends for content ideas, market research, or social media analysis in real time.

How to use

To use this MCP server with an MCP client, start the server using the runtime configuration below. You will access the available trending data through the CLI or any client that speaks the MCP protocol. The runtime exposes commands and environment controls to fetch YouTube trends, YouTube video data, YouTube comments, TikTok trends, and Instagram Reels trends.

How to install

Prerequisites you need before installation:

• Python 3.8+ (recommended)
• pip (Python package manager)
• Node.js/npm (if you plan to use optional MCP tooling)

Install the required Python packages. Run these commands in your terminal one per line:

pip install beautifulsoup4
pip install youtube-comment-downloader
pip install yt_dlp
pip install requests
pip install fastmcp

Prepare and start the MCP server. Use the stdio runtime configuration shown here to run the server with all needed plugins loaded.
