Browser Use
Lets AI do web tasks for you, such as filling forms, searching and extracting data, in the maker’s cloud browsers or on your computer.
Description from the maker (original English)
Live web access for agents: scrape, SERP search, crawl/map, 100+ collectors, datasets, proxies.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.

MCP server for browser use access
Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.
Connect QuanticData to Claude, Cursor, and any MCP client. Gives an AI agent live web access — scrape, search, map, and crawl — through residential proxies with real-browser TLS fingerprints, so pages that block ordinary bots come back clean. It also hands the agent raw proxy endpoints of every type (residential, mobile, datacenter, ISP, IPv6) from your active plans, ready to plug into any HTTP client.
It calls the public QuanticData Scraper API with your own qd_live_ key, so there are no internal secrets and you run it locally.
| Tool | What it does |
|---|---|
scrape | Scrape one URL → Markdown/HTML/text, including PDF/Office documents. Supports multi-format output, absolute link collection, JSON-LD metadata, structured CSS extraction, AI prompt/JSON-schema extraction, and mode: summary. |
unlock | Web Unlocker: replay any HTTP request (method, headers, body) through a residential exit with a real browser TLS fingerprint, retry on a fresh IP, escalate a blocked GET to a real browser. Returns the raw response (status, headers, body); a still-blocked page comes back flagged (blocked, blockClass, vendor), never as a silent 200. Interactive captchas are not solved (blockClass: "captcha"). |
seo_audit | Fetch a URL as a no-JS bot and fully rendered, return both SEO views + the diff (JS-only content, changed title/description, missing canonical) and bot-facing meta (robots, OG, JSON-LD). |
ai_visibility | Can ChatGPT, Claude, Perplexity, Google AI Overview and Bing Copilot read and cite a page? On-page audit (24 AI crawlers in robots.txt, Content-Signal, a fetch as GPTBot, noindex/nosnippet/noai, text without JS, JSON-LD entities, answer-shaped copy, dates with age, author, sources) scored per pillar with blockers, evidence and fixes — plus an optional citation panel that asks the engines and reports cited / mentioned / rank, share of voice and who wins the questions you are absent from. |
search | Structured Google/Bing/DuckDuckGo results. Set render: true for Google AI Overview, PAA, Knowledge Graph and other JS enrichments. |
search_and_read | SERP → fetch top pages → numbered citation-ready sources and one token-bounded context string ready for an AI prompt. |
search_bulk / search_bulk_status | Async multi-page pagination with merged organic results and page-one AI/zero-click enrichments. |
map | Fast URL discovery (sitemaps + homepage links), no full crawl. Compact by default: up to limit URLs (100) plus site-wide total and per-section summary; group_by: path for the path tree. |
crawl / crawl_status | Async BFS site crawl → Markdown per page; poll for progress. |
batch / batch_status | Scrape many URLs asynchronously; mode: summary for metadata-only items. Incremental polling via since cursor; page content only with include_content. |
create_dataset / dataset_status | Prompt-driven structured dataset collection with budget and row limits. |
list_collectors / run_collector / collector_run_status | Ready-made Collectors: run a versioned scraper with a semantic input (keyword + location, place id, product id, domain…) instead of URLs — Google Maps places, place reviews, Google Jobs/News/Shopping, product offers, hotels, local business leads, site contacts, company profile. Priced per delivered row; async runs poll by run_id, rows exportable as CSV. |
list_proxies | List your proxy services of every type — Residential Basic/Premium/Private, Mobile, Mobile V2, Datacenter, ISP, IPv6 — with bandwidth left, expiry and the orderId used to generate. |
generate_proxies | Ready-to-use proxy strings (credentials included) from any active plan: geo targeting (country/state/city/ISP/ASN), rotating or sticky sessions, HTTP or SOCKS5, several output formats. |
proxy_locations | Valid geo-targeting values per plan type: countries, states, cities, ASNs, or the full location tree with ISP codes. |
whitelist_ip | Manage IP-auth whitelisting (add/list/remove) for plans that support it, including the Mobile V2 IP-auth proxy list. |
report | Send feedback to the team from inside the agent: a bug (wrong/empty result, error, blocked page), a missing feature or collector, a question. Works without an API key. |
No install needed — npx fetches quanticdata-mcp on demand (Node.js 18+).
Claude Code (one command):
claude mcp add quanticdata \
-e QUANTICDATA_API_KEY=qd_live_your_key_here \ -- npx -y quanticdata-mcp
Claude Desktop / Cursor / any MCP client (claude_desktop_config.json, .cursor/mcp.json, or .mcp.json):
{
"mcpServers": { "quanticdata": { "command": "npx", "args": ["-y", "quanticdata-mcp"], "env": { "QUANTICDATA_API_KEY": "qd_live_your_key_here" } } } }
The same server also runs as a hosted Streamable HTTP endpoint, for clients that prefer a URL over a local package:
https://api.quanticdata.io/mcp
The endpoint supports the MCP authorization spec (OAuth 2.1). In a client that supports it, add the URL above as a remote server and nothing else:
MCP · appears on the dashboard API keys page; delete it to disconnect the client.Under the hood: authorization server metadata at https://app.quanticdata.io/.well-known/oauth-authorization-server, protected resource metadata at https://api.quanticdata.io/.well-known/oauth-protected-resource/mcp, dynamic client registration (RFC 7591) and Client ID Metadata Documents, PKCE (S256) required, 1-hour access tokens with rotating refresh tokens, tokens bound to this endpoint (RFC 8707). Usage is billed to your balance like any key.
Clients that take a bearer token can skip OAuth: the key travels per request in the Authorization header (or X-Api-Key), nothing is stored server-side.
curl -X POST https://api.quanticdata.io/mcp \
-H "Authorization: Bearer qd_live_your_key_here" \ -H "Content-Type: application/json" \ -H "Accept: application/json, text/event-stream" \ -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
A request with neither a token nor a key gets 401 with a WWW-Authenticate header pointing at the metadata above: that is what makes OAuth-capable clients start the sign-in.
Self-hosting the endpoint is a second binary in this same package. With QUANTICDATA_API_KEY set it serves that one account to callers that send no credential:
QUANTICDATA_API_KEY=qd_live_… PORT=9310 npx -y quanticdata-mcp-remote
npm install
npm run build
Then point the client at the local build instead of npx:
{
"mcpServers": { "quanticdata": { "command": "node", "args": ["/absolute/path/to/scraper-mcp/dist/index.js"], "env": { "QUANTICDATA_API_KEY": "qd_live_your_key_here" } } } }
| Var | Default | Notes |
|---|---|---|
QUANTICDATA_API_KEY | — | Required. Your qd_live_ key. |
QUANTICDATA_API_BASE | https://api.quanticdata.io/v1 | Override for staging/self-host. |
QUANTICDATA_TOOLS | all 28 | Load only some tools: names (search,scrape) or a preset (lite, web, research, collectors, proxies). See below. |
Self-hosted remote endpoint only (quanticdata-mcp-remote), optional:
| Var | Default | Notes |
|---|---|---|
MCP_OAUTH_RESOURCE | https://api.quanticdata.io/mcp | This endpoint as an OAuth resource. |
MCP_OAUTH_ISSUER | https://app.quanticdata.io | Authorization server advertised in the resource metadata. |
MCP_OAUTH_INTROSPECT_URL | http://127.0.0.1:3090/api/v1/internal/oauth/introspect | Where OAuth access tokens are checked. |
MCP_INTERNAL_TOKEN | — | Secret for the introspection call. Unset = only API keys are accepted. |
The 28 tool definitions are about 14,000 tokens. A local model on Ollama's default 4K context cannot hold them, and a 32K context loses almost half its room before the first page. Load fewer tools:
| Preset | Tools | Definition tokens |
|---|---|---|
lite | search_and_read | ~360 |
web | search, search_and_read, scrape | ~4,200 |
research | web + map, batch, batch_status | ~5,100 |
collectors | list_collectors, run_collector, collector_run_status | ~830 |
proxies | list_proxies, generate_proxies, proxy_locations, whitelist_ip | ~1,800 |
Over stdio set QUANTICDATA_TOOLS=web. On the hosted endpoint add ?tools=web to the URL and send your API key as a Bearer header: https://api.quanticdata.io/mcp?tools=web. Names can be combined: ?tools=lite,collectors.

What this server sends. It runs on your machine and talks only to the public QuanticData API at https://api.quanticdata.io/v1, authenticated with your own qd_live_ key. Each call carries the arguments you (or your agent) passed — the target URL or query, and any extraction prompt. Nothing else on your machine is read or transmitted: the server has no filesystem, shell or clipboard access.
What we collect. Account data you give us (name, email, billing details) and a request log kept for billing, abuse prevention and support: target URL or query, timestamp, response status, bytes transferred and the API key used. We do not retain scraped page content beyond what is needed to return your result.
Data you collect through the service. You decide what public web data to collect and you are the controller of that data — we process it on your behalf only to fulfil your request. You are responsible for using the service lawfully, for respecting the terms of the sites you access, and for any personal data you collect through it.
Sharing. We do not sell personal data. We share it only with the processors that run the service — payment providers, email delivery, hosting, CDN and analytics — under contracts that bind them to protect it, and with the upstream proxy networks that route your traffic (connection metadata only, never your account details). We may disclose data where required by law.
Retention. Account data for as long as the account exists; request logs on a rolling window for billing and abuse investigation. You can request deletion at any time.
Your key. Claude Desktop stores it in the OS keychain and passes it to this server as an environment variable. It is never written to the bundle and never sent anywhere except the QuanticData API. Revoke or rotate it at https://app.quanticdata.io/api-keys.
