此 MCP 可以做什么

Searches, scrapes, crawls, screenshots, maps, and extracts structured data from websites, with utilities for company branding and site style analysis.

batch
Batch
Scrape a list of URLs you already have as one job. Returns a batch id straight away; read it with batch_status.

{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['urls'], 'properties': {'urls': {'type': 'array', 'items': {'type': 'string'}, 'maxItems': 25000, 'minItems': 1, 'description': 'The URLs to scrape.'}}}
batch_status
Batch status
Read a batch started with batch: how far it has got, and the results so far.

brand
Brand
A company's brand from its domain: logos for light and dark backgrounds, its real colours, name, description and socials. Answers 'what is this company' far better than a raw page dump.

crawl
Crawl
Discover and scrape a whole site as one job. Returns a crawl id straight away; read it with crawl_status. Use this instead of calling scrape in a loop.

crawl_status
Crawl status
Read a crawl started with crawl: how far it has got, and the pages it has scraped.

images
Images
Harvest a page's images with their metadata, without rendering it. Cheaper than a screenshot and returns the source images rather than a picture of the page.

logo
Logo
A company's logo as a directly embeddable image URL, chosen for the background you name. Use this rather than brand when the mark is all you need — it costs a fifth as much and returns one asset instead of the whole record.

Defaults to light.'}, 'domain': {'type': 'string', 'description': 'The company domain, e.g. stripe.com. A full URL works too.'}}}
map
Map
Enumerate a site's URLs from its sitemap and links, without scraping them.

Default false optimises for raw content and can return unstructured text on marketing and listing pages. Turn on when the document structure matters, or retry with it if `structure` came back 'plain'."}}}
screenshot
Screenshot
Render a page in a real browser and capture a PNG, returning its public URL. Use when the question is what the page looks like rather than what it says.

With fullPage the capture still extends to the full page height.'}}}

Search the web and return ranked results: title, url and snippet. Set scrapeResults to also fetch each result as markdown, at 1 extra credit per page.

styleguide
Styleguide
A site's design system read from computed styles in a real browser: colours by role with contrast ratios, the type scale, corner radius and button styling. Values defined through CSS variables come back resolved to the hex actually painted.
