Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟢scrape(url, formats, preferStructure)
Turn a URL into clean, LLM-ready markdown and structured data.
Input Schema
{
"type": "object",
"properties": {
"url": {
"type": "string",
"description": "The URL to scrape."
},
"formats": {
"description": "Which outputs to return. Defaults to markdown.",
"type": "array",
"items": {
"type": "string",
"enum": [
"markdown",
"html",
"rawHtml",
"links",
"structured"
]
}
},
"preferStructure": {
"description": "Keep headings, lists and tables as markdown. 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'.",
"type": "boolean"
}
},
"required": [
"url"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢map(url, limit)
Enumerate a site's URLs from its sitemap and links, without scraping them.
Input Schema
{
"type": "object",
"properties": {
"url": {
"type": "string",

"limit": {
"description": "Max URLs to return.",

"maximum": 5000
}
},
"required": [
"url"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢crawl(url, limit, maxDepth)
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.
Input Schema
{
"type": "object",
"properties": {
"url": {
"type": "string",
"description": "The site to start from."
},
"limit": {
"description": "Maximum pages to scrape.",

"maximum": 500
},
"maxDepth": {
"description": "How far from the seed to follow.",
"type": "integer",
"minimum": 0,
"maximum": 9007199254740991
}
},
"required": [
"url"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢crawl_status(crawlId)
Read a crawl started with crawl: how far it has got, and the pages it has scraped.
Input Schema
{
"type": "object",
"properties": {
"crawlId": {
"type": "string",
"description": "The id returned by crawl."
}
},
"required": [
"crawlId"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢batch(urls)
Scrape a list of URLs you already have as one job. Returns a batch id straight away; read it with batch_status.
Input Schema
{
"type": "object",
"properties": {
"urls": {
"minItems": 1,
"maxItems": 25000,
"type": "array",
"items": {
"type": "string"
},
"description": "The URLs to scrape."
}
},
"required": [
"urls"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢batch_status(batchId)
Read a batch started with batch: how far it has got, and the results so far.
Input Schema
{
"type": "object",
"properties": {
"batchId": {
"type": "string",
"description": "The id returned by batch."
}
},
"required": [
"batchId"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢search(query, limit, scrapeResults, preferStructure)
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.
Input Schema
{
"type": "object",
"properties": {
"query": {
"type": "string",
"description": "The search query."
},
"limit": {
"description": "Max results (default 5).",
"type": "integer",
"minimum": 1,
"maximum": 15
},
"scrapeResults": {
"description": "Also scrape each result to markdown, 1 extra credit per page (default false).",
"type": "boolean"
},
"preferStructure": {
"description": "Keep headings, lists and tables in each scraped result.",
"type": "boolean"
}
},
"required": [
"query"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢brand(domain)
A company's brand from its domain: logos for light and dark backgrounds, its real colours, name, description and socials. Answers 'what is this company' far better than a raw page dump.
Input Schema
{
"type": "object",
"properties": {
"domain": {
"type": "string",
"description": "The company domain, e.g. stripe.com. A full URL works too."
}
},
"required": [
"domain"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢logo(domain, theme, type)
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.
Input Schema
{
"type": "object",
"properties": {
"domain": {
"type": "string",
"description": "The company domain, e.g. stripe.com. A full URL works too."
},
"theme": {
"description": "The background the logo will sit on. Defaults to light.",
"type": "string",
"enum": [
"light",
"dark",
"auto"
]
},
"type": {
"description": "The square mark, or the full logotype. Defaults to icon.",
"type": "string",
"enum": [
"icon",
"wordmark"
]
}
},
"required": [
"domain"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢extract(urls, prompt, schema, preferStructure, showConfidence, ...)
Pull typed structured data from one or more URLs by JSON schema or prompt.
Input Schema
{
"type": "object",
"properties": {
"urls": {
"minItems": 1,
"type": "array",
"items": {
"type": "string"
},
"description": "The URLs to extract from."
},
"prompt": {
"description": "Natural-language description of what to pull.",
"type": "string"
},
"schema": {
"description": "A JSON schema the result must conform to.",
"type": "object",
"propertyNames": {
"type": "string"
},
"additionalProperties": {}
},
"preferStructure": {
"description": "Keep headings, lists and tables in the text handed to the model.",
"type": "boolean"
},
"showConfidence": {
"description": "For each field, return a confidence score and the exact source passage the value was drawn from.",
"type": "boolean"
},
"showSources": {
"description": "Return the list of URLs that were actually extracted.",
"type": "boolean"
}
},
"required": [
"urls"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢styleguide(domain)
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.
Input Schema
{
"type": "object",
"properties": {
"domain": {
"type": "string",
"description": "The domain to read, e.g. stripe.com. A full URL works too."
}
},
"required": [
"domain"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢screenshot(url, fullPage, viewport, viewportWidth, viewportHeight, ...)
Render a page in a real browser and capture a PNG, returning its public URL. Use when the question is what the page looks like rather than what it says.
Input Schema
{
"type": "object",
"properties": {
"url": {
"type": "string",
"description": "The URL to capture."
},
"fullPage": {
"description": "Capture the whole scrollable page rather than the viewport.",
"type": "boolean"
},
"viewport": {
"description": "Screen size to render at. Defaults to desktop (1920x1080). Ignored when width or height are given.",
"type": "string",
"enum": [
"desktop",
"laptop",
"tablet",
"mobile"
]
},
"viewportWidth": {
"description": "Exact viewport width in pixels. Overrides viewport.",
"type": "integer",
"minimum": 320,
"maximum": 3840
},
"viewportHeight": {
"description": "Exact viewport height in pixels. Overrides viewport. With fullPage the capture still extends to the full page height.",
"type": "integer",
"minimum": 240,
"maximum": 2160
},
"waitFor": {
"description": "Extra milliseconds to let the page settle before capture.",
"type": "integer",
"minimum": 0,
"maximum": 30000
},
"timeout": {
"description": "Overall time budget for the capture, in milliseconds.",
"type": "integer",
"minimum": 1000,
"maximum": 120000
},
"maxAge": {
"description": "Reuse a stored screenshot younger than this many milliseconds. Defaults to 7 days, so a repeat returns the stored PNG without re-rendering and without applying waitFor. Pass 0 to force a fresh capture.",
"type": "integer",
"minimum": 0,
"maximum": 9007199254740991
}
},
"required": [
"url"
],
"$schema": "http://json-schema.org/draft-07/schema#"
}🟢images(url)
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.
Input Schema
{
"type": "object",
"properties": {
"url": {
"type": "string",
"description": "The page to harvest images from."
}
},
"required": [
"url"
],
"$schema": "http://json-schema.org/draft-07/schema#"
