MCP tools · 10 exposed · ~1,838 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
answers ~168

Answer a factual question using web search, optionally shaped into a flat JSON object of fields (returned with sources and citations). Best for a bounded, factual answer (e.g. a company's founding year, a product's current price). It is NOT reliable for enumerating a live list from a page (e.g. 'the latest N blog posts with titles and dates'). For that, use create_map or get_webpage_content on the page and read the results instead.

NameTypeReqDescription
jsonOptional shape for the answer: a flat JSON object of the fields you want. Example: { "book_title": "", "author": "", "release_date": "" }. Keep it flat. Deeply nested shapes or long lists are unrelia…
taskstringyesQuestion or task to answer using web data.

No examples provided.

batch_scrape_urls ~334

Scrape a SPECIFIC, KNOWN list of URLs (typically from different domains). **Do NOT use this for crawling a website** - if the user wants to scrape a whole site or 'crawl' a domain, use `create_crawl` instead. Use this only when you already have an explicit list of URLs to scrape (e.g., user provides a CSV of URLs, or you need to scrape unrelated pages). Returns a batch_id immediately. Use `get_batch_results` with the batch_id to fetch the scraped content once the batch completes (~5–8 min). Set `wait_for_completion_seconds` to poll automatically.

NameTypeReqDescription
countrystringOptional country code for location-specific scraping.
output_formatstringChoose format for all URLs. Default: "markdown".
parserstringOptional parser ID for specialized extraction (e.g. @olostep/google-search).
urlsarrayArray of URLs to scrape — plain URL strings, or objects with "url" and optional "custom_id".
urls_to_scrapearrayAlias for `urls`.
wait_before_scrapingintegerWait time in milliseconds before scraping each URL.
wait_for_completion_secondsintegerSeconds to wait for batch completion. If >0, polls every 10s until done or timeout, then returns status. Use 0 to return immediately with batch_id (then call get_batch_results later). Recommended: 60…

create_crawl ~270

**PREFERRED tool for crawling a website.** Use this whenever the user says 'crawl', 'scrape the whole site', 'get all pages from a site', or wants multiple pages from a single domain. This is the CORRECT tool for any whole-site scraping task. **Do NOT use `batch_scrape_urls` for crawling** - that tool is only for when you already have a specific list of unrelated URLs from different domains. Starts an ASYNC crawl that autonomously discovers and scrapes pages by following links from a start URL. Returns a crawl_id - the crawl runs in the background. You MUST then call `get_crawl_results` with the returned crawl_id to poll status and retrieve the scraped pages. Do NOT call `get_batch_results` with a crawl_id - crawls and batches are separate resources.

NameTypeReqDescription
countrystringOptional country code for location-specific crawling.
max_pagesintegerMaximum number of pages to crawl. Set to 1 to scrape only the start URL.
output_formatstringFormat for scraped content. Default: "markdown".
parserstringOptional parser ID for specialized content extraction.
start_urlstringAlias for `url`.
urlstringStarting URL for the crawl.

No output schema declared.

No examples provided.

create_map ~206

Get a LIST of URLs on a website (URL discovery only — does NOT scrape content). Use when the user wants a list of links: 'show me all URLs on this site', 'map this website', or when you want to surface candidate URLs to the user before scraping a subset. Prefer `create_crawl` if the goal is to scrape the whole site — it discovers AND scrapes in one workflow. Use this only when the URL list itself is the deliverable.

NameTypeReqDescription
exclude_url_patternsarrayOptional glob patterns to exclude (e.g., "/admin/**").
include_url_patternsarrayOptional glob patterns to include (e.g., "/blog/**").
search_querystringOptional search query to filter URLs (e.g., "blog").
top_nintegerOptional limit for number of URLs returned.
urlstringWebsite URL to extract links from.
website_urlstringAlias for `url`.

No output schema declared.

No examples provided.

get_batch_results ~126

Retrieve the status and scraped content for a batch job. Pass the batch_id returned by batch_scrape_urls. If the batch is completed, returns the scraped content for each URL. If still in_progress, returns the current status so you can call again later.

NameTypeReqDescription
batch_idstringyesThe batch_id (or id) returned from batch_scrape_urls.
formatsarrayContent formats to retrieve per URL. Default: ["markdown"].
items_limitintegerMax number of items to retrieve content for (1-100). Default: 20.

No output schema declared.

No examples provided.

get_crawl_results ~207

Retrieve the status and scraped pages for a crawl job. Pass the crawl_id returned by create_crawl. If the crawl is still in_progress, returns the current status so you can call again later (poll every ~10 seconds). Once completed, returns the list of discovered pages with their scraped content in the requested formats. This is the REQUIRED companion to create_crawl — create_crawl only kicks off the async job, this tool is how you actually get the content.

NameTypeReqDescription
crawl_idstringyesThe crawl_id (or id) returned from create_crawl.
cursorintegerPagination cursor for list-pages. Default: 0 (first page).
formatsarrayContent formats to retrieve per page. Default: ["markdown"].
items_limitintegerMax number of pages to retrieve content for (1-100). Default: 20.
search_querystringOptional filter to rank/select pages by relevance to a query.

No output schema declared.

No examples provided.

get_webpage_content ~90

Retrieve content of a webpage in markdown

NameTypeReqDescription
countrystringResidential country to load the request from (e.g., US, CA, GB). Optional.
urlstringThe URL of the webpage to scrape.
url_to_scrapestringAlias for `url`.
wait_before_scrapingintegerTime to wait in milliseconds before starting the scrape.

No output schema declared.

No examples provided.

get_website_urls ~107

Search and retrieve relevant URLs from a website (URL discovery only - does NOT scrape content). Use this only when the user wants a *filtered list of links* matching a search query. **Do NOT use this as a precursor to scraping** - if the user wants to scrape/crawl a site, use `create_crawl` directly.

NameTypeReqDescription
search_querystringyesThe search query to sort URLs by.
urlstringyesThe URL of the website to map.

No output schema declared.

No examples provided.

scrape_website ~274

Extract content from a single URL. Supports multiple formats and JavaScript rendering.

output_formatstringOutput format. "markdown" (default), "html", and "text" need no extra config. "json" returns STRUCTURED data and requires either a `parser` OR an `llm_extract` schema describing the fields to pull. D…
