WhatsUpDoc (downmarked) MCP Server

What is WhatsUpDoc?

WhatsUpDoc is a command-line tool that fetches developer documentation from any website, converts it to Markdown using the Model Context Protocol (MCP), and saves it locally. It is intended for developers who want to store documentation offline or as local Markdown files.

How to use WhatsUpDoc?

Install globally with npm install -g downmarked, then run downmarked fetch <url> to fetch and save documentation. Use options like -o for output path, -s for a CSS selector, -r for recursive linked pages, -d for max depth, and --split to split by headers into separate files.
