Tools & capabilities

Exa MCP Server tools 2

  • web_search_exaSearch the web for any topic and get clean, ready-to-use content. Best for: Finding current information, news, facts, people, companies, or answering questions about any topic. Returns: Clean text content from top search results. Query tips: describe the ideal page, not keywords. "blog post comparing React and Vue performance" not "React vs Vue". Use category:people / category:company to search through Linkedin profiles / companies respectively. If highlights are insufficient, follow up with web_fetch_exa on the best URLs.
  • web_fetch_exaRead a webpage's full content as clean markdown. Use after web_search_exa when highlights are insufficient or to read any URL. Best for: Extracting full content from known URLs. Batch multiple URLs in one call. Returns: Clean text content and metadata from the page(s).

Olostep MCP Server tools 10

  • create_mapGet 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.
  • create_crawl**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.
  • get_crawl_resultsRetrieve 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.
  • batch_scrape_urlsScrape 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.
  • get_batch_resultsRetrieve 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.
  • answersAnswer 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.
  • search_webSearch the web for a given query and return structured results (non-AI, parser-based).
  • scrape_websiteExtract content from a single URL. Supports multiple formats and JavaScript rendering.
  • get_webpage_contentRetrieve content of a webpage in markdown
  • get_website_urlsSearch 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.
