How It Works

WhatsUpDoc (downmarked) uses the Model Context Protocol (MCP) to standardize communication between the CLI and the documentation server. The tool:

1. Fetches HTML content from the specified URL
2. Parses the HTML using Cheerio
3. Converts the HTML to Markdown using Turndown
4. Saves the Markdown to the specified location
