What is the Web Scraper MCP Server?
Connect the Web Scraper utility to any AI agent to give it direct access to the public internet. Instead of letting the AI hallucinate facts, allow it to read real-time articles, parse documentation, and fetch clean text from any URL you provide.
What you can do
- Reader View — Convert any cluttered webpage into pristine, readable Markdown by stripping out ads, navbars, and boilerplate using Mozilla Readability logic
- Site Crawling — Instruct the AI to crawl a starting URL (like a documentation hub or wiki) up to 10 pages deep automatically
- Batch Processing — Fetch up to 10 different URLs in parallel to compare articles or summarize multiple sources at once
- Metadata Extraction — Quickly pull SEO titles, descriptions, OG tags, canonical links, and all outbound hyperlinks without downloading the entire page body
How it works
- Subscribe to this server
- No API keys or authentication required
- Simply paste a link in your chat and tell your agent to 'read this URL' or 'crawl this documentation'
Who is this for?
- Developers — point the agent to a new library's API docs and have it write code using the absolute latest syntax
- Researchers — drop a handful of Wikipedia links and ask the AI to synthesize a comprehensive summary from the fetched data
- SEO Specialists — audit a webpage's metadata, extracted titles, and outbound link structure dynamically
Built-in capabilities (5)
All URLs are fetched in parallel. Maximum 10 URLs per batch. Fetch multiple web pages in parallel
Maximum 10 pages to keep response size manageable. Crawl a website starting from a URL
Returns: title, description, OG tags, lang, author, robots, canonical, link count. For the full page content, use the read tool instead. Extract structured metadata from a web page: title, description, OG tags, and more
Internal links share the same hostname as the source page. Extract all hyperlinks from a web page
Uses @mozilla/readability (Firefox Reader View) to extract the main article content, then converts to Markdown. Works best for articles, docs, blogs, and Wikipedia. Fetch any public web page and return its full content as clean Markdown

Frequently asked questions
Can it read documentation sites that are split into multiple pages?
Yes! You can use the crawl tool. For example: 'Crawl the getting started guide at https://example.com/docs'. The agent will fetch the starting page and automatically follow inner links to gather up to 10 pages of context.
How does it handle ads and cluttered websites?
The read tool uses the same underlying technology as Firefox's 'Reader View' (@mozilla/readability). It intelligently strips out standard website boilerplate—like navbars, sidebars, footers, and ads—leaving only the title and the clean main article text converted to Markdown.
Is there a limit on how many URLs I can batch process?
Yes, to ensure conversational AI latency remains reasonable, the batch_read tool accepts a maximum of 10 URLs in a single request. All 10 URLs are fetched simultaneously in parallel for maximum speed.
How does LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
