What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs on your computer
Transport: stdio
Category: Web & browsers

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

You need

DockerDocker installed

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "crw": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/us/crw:latest",
        "crw-mcp"
      ]
    }
  }
}

Run this in your terminal

claude mcp add crw -- docker run -i --rm ghcr.io/us/crw:latest crw-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "crw": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/us/crw:latest",
        "crw-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "crw": {
      "type": "stdio",
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "ghcr.io/us/crw:latest",
        "crw-mcp"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Runs on your computer; the tool list appears in your AI app after you install it.

Common questions

Is CRW Web Scraper safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.36.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Docker on your computer.

What can I use instead?

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.

fastCRW

Turn URLs into clean markdown or structured JSON with one engine for search, scrape, map, crawl, and extract.

Run it locally as a small Rust binary or use the managed API.

Get 1000 free credits → · Install · Docs

No credit card. Continue with GitHub.

One-command install

curl -fsSL https://fastcrw.com/install | sh

Runs local and free, no account needed. To use the Cloud, paste your key into the same command and it installs the binary, connects the key, and registers the MCP server with the AI coding tools you already have:

curl -fsSL https://fastcrw.com/install | CRW_API_KEY=crw_live_... sh

crw search "rust tutorials"

Claude Code, Cursor, Codex, Gemini CLI, OpenCode and Windsurf are picked up automatically when they are already set up; nothing else is touched, and your key stays in ~/.config/crw/config.toml rather than being copied into each tool. Add CRW_NO_AGENTS=1 to skip that step, or run crw setup on its own to choose interactively.

1000 free credits, no credit card. Managed proxies, JS rendering and search, with nothing to run or keep up to date. Get my free key →

What it does

Operation	Outcome
Scrape	One URL to markdown, HTML, links, screenshots, or schema JSON
Crawl	Follow a bounded site crawl and collect its pages
Map	Discover URLs without scraping every page
Search	Search the web and optionally scrape selected results
Extract	Produce structured fields from one or many URLs

Why fastCRW

On Firecrawl's own public 1,000-URL dataset, fastCRW recovered more truth than Crawl4AI and Firecrawl, matched the fastest median latency, and idled at ~14 MB RAM.

Methodology, full numbers, and how to reproduce it

On a different benchmark entirely, answer accuracy rather than scrape recall, fastCRW answers 90.0% of the 600 AA-Omniscience questions correctly. Every product listed on the Artificial Analysis Search Index sits below it.

Choose how you use it

CLI

crw https://example.com            # scrape, works right after install

crw search "rust async runtime" # search, after crw setup

Python SDK

Using Cloud? Get an API key, then export it once:

export CRW_API_KEY="crw_live_..."

pip install crw

from crw import CrwClient

client = CrwClient() page = client.scrape("https://example.com", formats=["markdown"])

print(page["markdown"])

Node.js

npm install crw-sdk

import { CrwClient } from "crw-sdk";

const client = new CrwClient();

const page = await client.scrape("https://example.com", { formats: ["markdown"], });

console.log(page.markdown);

MCP for AI agents

npx -y crw-mcp@latest install

Installs the CRW skill and MCP server in your detected AI tools. crw setup can also do this step, so either path is enough. Manual setup →

Choose where it runs

	Managed API	Local / self-hosted
Best for	Zero infrastructure and managed scaling	Data control, private networks, or custom infrastructure
Start	Create an API key, then `crw setup`	Install and run `crw`
Operations	Managed proxies, billing, and hosted capabilities	You choose renderers, search, auth, proxies, and capacity
