MCP servers for web research
You paste a link. The AI confidently summarizes it. The summary is wrong, or thin, or describes a loading spinner. Nobody warned you it couldn’t actually see the page.
Here’s what happened: the server sent a near-empty HTML shell and a pile of JavaScript. A browser runs that script and builds the real page. A basic fetch tool never does. So on single-page apps, JS-rendered content, lazy-loaded sections and anything behind an interaction, the AI reads the shell and improvises the rest.
The fix isn’t a smarter model, it’s a better reader. These are the MCP servers that give Claude one.
Disclosure, up front: we build Enrichr, so it appears on this list. We’ve tried to say exactly why, and to be straight about where the others are the better tool.
01 Enrichrour pick
Enrichr renders the page in a real browser, then reports on what appeared: the post-JavaScript DOM, structured data, headings, links, assets, even the animations and canvas content. scrape_url is the quick way to get clean markdown from one page; crawl_site and batch_scrape handle many. It also includes OCR and PDF parsing for content that isn’t HTML at all. Best when the page is dynamic and you need to trust what you’re reading.
02 Firecrawl
Turns pages and whole sites into LLM-friendly markdown and structured data. A popular choice for large scraping and crawling jobs where clean text is the goal.
03 Playwright
General browser control. When the content is behind a click, a login you’re authorized to use or a multi-step flow, Playwright lets Claude perform the steps and read the result.
04 Brave Search
Search is a different job from reading. Brave’s search API gives Claude a way to find pages in the first place, then hand them to a reader.
05 Fetch
The lightweight reference server for pulling a URL’s content and converting it to markdown. Fast and simple, and fine for static pages. Just know its limits: it isn’t a browser.
06 Chrome DevTools
Read network requests and the console. Sometimes the data you want isn’t in the page at all; it’s in the API call the page makes, and DevTools shows you which one.
07 PubMed
For scientific and medical research, a dedicated source beats scraping every time: search articles, read metadata, follow citations from the primary literature.
08 Google Drive
Your own documents are part of “the web” for research purposes. Pair external sources with the notes and papers you already have.
