AlterLab web scraping MCP server
by RapierCraft
Let your AI open web pages, pull out the details you want, and take screenshots for you.
This is a helper that lets your AI assistant visit websites and bring back what is on them. It is handy when a page is hard to read, blocked, or full of clutter, and you just want the useful parts. You ask in normal words, and the AI does the fetching for you.
What is an MCP server? The 30-second version
On its own, your AI can only chat with you using what it already knows. An MCP server is a small helper program you connect once, and it gives your AI a new skill. This one gives your AI a way to reach out to AlterLab, a web scraping service, so it can open pages, read them, and take pictures of them. After you set it up, you can simply ask your AI to go look at a page, and it will use this helper to do it.
What this MCP server does
You ask your AI something like "scrape this page and tell me the price". Your AI passes that request to this helper, which sends it to the AlterLab service. AlterLab fetches the page for you, even if the site tries to block automated visits or needs a moment for its content to load. Then it sends the result back, and your AI shows it to you in the chat as text, a tidy list, or a picture.

Try asking your AI
- “Scrape this product page and tell me the name, price, and rating”
- “Take a screenshot of our landing page”
- “Extract all the FAQ questions and answers from this help page”
- “How much would it cost to scrape this site?”
What it gives back to you
You get back whatever you asked for, right in the chat. That might be a summary in plain text, a tidy list of fields like name and price, or a screenshot image you can look at. If you asked about cost or balance, you get a simple number or short answer.
Before you start
What you need
- An AlterLab account (free to sign up, and it comes with $1 of free credit)
- An AlterLab API key from your dashboard (a kind of password the site gives you)
- Node.js installed on your computer so the helper can run
- An AI app that supports MCP servers, like Claude Desktop, Claude Code, Cursor, or Windsurf
Good to know
It uses your AlterLab credit each time it scrapes, so keep an eye on your balance, and the saved login sessions hold real cookies from your accounts, so treat them like passwords.
