Setup requires a single config entry or a `claude mcp add` command, with the API key passed in the URL or an Authorization: Bearer header, and new accounts start with 1,000 free credits.", "body_md": "Large language models know a lot, but they don't know what changed on a website this morning. If you use Claude Code, Claude Desktop, Cursor or another MCP client, you can close that gap by connecting a web data server through the Model Context Protocol (MCP). This post explains what that gives you, how to set it up in a few minutes, and how to use it without wasting tokens.\n\nWhat MCP adds\n\nMCP is an open protocol that lets an AI client call external tools. A web scraping MCP server exposes tools such as \"scrape this URL\" or \"search the web\" that the assistant can call on its own when a task needs fresh information: reading the latest docs for a library, checking a changelog, comparing pricing pages, or collecting examples from a site.\n\nWhich tools you get\n\nAs an example, the [XCrawl](https://www.xcrawl.ai/) MCP server (npm package xcrawl-mcp, for the XCrawl web data API) exposes these tools:\n\nOption 1: the hosted endpoint\n\nThe simplest setup uses the hosted MCP URL, so nothing runs on your machine. In Claude Desktop's claude_desktop_config.json:\n\n```\n{\n  \"mcpServers\": {\n    \"xcrawl\": {\n      \"url\": \"https://mcp.xcrawl.com/YOUR_API_KEY/mcp\"\n    }\n  }\n}\n```\n\nIn Claude Code you can add the same endpoint from the terminal:\n\n```\nclaude mcp add --transport http xcrawl https://mcp.xcrawl.com/YOUR_API_KEY/mcp\n```\n\nThe server also accepts the key in an Authorization: Bearer header if you'd rather keep it out of the URL.\n\nOption 2: run it locally over stdio\n\nIf you prefer a local process (Node.js 18+):\n\n```\nXCRAWL_API_KEY=YOUR_API_KEY npx -y xcrawl-mcp\n```\n\nor register it with Claude Code:\n\n```\nclaude mcp add xcrawl -e XCRAWL_API_KEY=YOUR_API_KEY -- npx -y xcrawl-mcp\n```\n\nPrompts that work well\n\nKeeping it efficient\n\nWrapping up\n\nConnecting a web data MCP server turns your assistant from \"trained up to some date\" into something that can check the live web when it matters. Setup is a single config entry, and new XCrawl accounts start with 1,000 free credits, which is plenty to try the workflow on your own projects.
