电商价格监控
跨数百个电商网站追踪竞争对手价格与产品库存情况。
面临的问题
电商团队每天需要监控数百个产品页面上的竞争对手定价。人工核查难以规模化，而传统抓取程序在网站更新布局后便会失效。
解决方案
CrawlForge 的 batch_scrape 可并行处理数百个 URL，track_changes 则会自动检测价格与库存变化。当竞争对手调整定价时，你将收到提醒。
代码示例
// Monitor competitor prices across product pages
const products = await mcp.batch_scrape({
urls: [
"https://competitor-a.com/product/widget-pro",
"https://competitor-b.com/products/widget-pro",
"https://competitor-c.com/shop/widget-pro",
],
selectors: {
price: ".product-price",
availability: ".stock-status",
title: "h1.product-title",
},
});
// Track changes since last check
const changes = await mcp.track_changes({
url: "https://competitor-a.com/product/widget-pro",
selectors: [".product-price", ".stock-status"],
});
console.log(changes.diff);使用的工具
