Qué hace este MCP

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

batch

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

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.

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.

map
Map

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.

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.
