Feature & Specification Comparison
Tools & Capabilities Breakdown
Scrapeunblocker MCP Tools (4)
fetch_html
Fetch the fully rendered HTML of any web page through ScrapeUnblocker, bypassing anti-bot protection (Cloudflare, DataDome, PerimeterX, Akamai, Shape). Use this when a normal fetch is blocked (403/429, captcha, 'access denied') or when the page needs a real browser to render. Returns the raw HTML as text.
For pages that need interaction (accept a cookie banner, click a tab, type into a search box, scroll to trigger lazy loading) pass `steps`: an ordered list of browser actions run in a real browser AFTER the page loads, then the resulting HTML is returned. Workflow: first call the `list_elements` tool to discover the real selectors on the page, then build `steps` against them. Steps are NOT idempotent - they run once per call. If a step fails, this tool returns which step failed, why, and the page HTML at that moment so you can fix the selector and retry.
list_elements
Load a page through ScrapeUnblocker and return a JSON list of its notable elements (links, inputs, buttons, selects, etc.) with a ready-to-use `selector` for each, plus tag, text and useful attributes (name, id, type, placeholder, aria_label, href, ...). Read-only and does not interact with the page. This is the discovery half of interactive scraping: call `list_elements` to find the selectors you need, then pass matching `steps` to `fetch_html` to click/type/select and capture the resulting HTML.
fetch_parsed
Fetch a web page through ScrapeUnblocker and return AI-parsed structured JSON instead of raw HTML (e.g. product details, article content). Best for extracting fields from product, listing or article pages without writing your own HTML parsing.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
