wtf is master-fetch?

Hound is a free tool that gives AI coding assistants like Claude Code or Cursor the ability to browse the web, search, and read documents. Normally, an AI assistant is stuck looking at the code on your computer and cannot see the internet. This tool connects to your AI assistant and lets it independently search the web, visit websites (even those with bot-blockers), and read PDFs, all without requiring any paid API keys or accounts. When you ask your AI assistant to research something, Hound does the heavy lifting behind the scenes. If a website blocks automated visits, it automatically switches to a special stealthy browser to get around the block. It can also extract just the text you care about from a long page, crawl entire websites to find documentation, and even read scanned PDFs using optical character recognition. It runs completely on your own machine, so no data is sent to a third-party service. This is built for developers, founders, or anyone using AI coding assistants who needs their AI to have real-time information. For example, if you are trying to fix a bug in a newly updated software library, you could ask your AI to search the web for the latest documentation, read the relevant forum posts, and figure out the solution. The AI can pull all of this context back into your project automatically. What makes this project notable is its all-in-one, zero-cost approach. Many existing tools handle only one task, like searching the web or reading PDFs, and often require paid accounts. This combines searching, fetching, crawling, and document reading into a single local tool. It is also designed to be very communicative: instead of just dumping raw webpage text back to the AI, it provides structured signals like a relevance score, a summary, and clear error messages if a page is blocked. This helps the AI understand exactly what it is looking at and decide what to do next.
