crw 0.3.5

Python SDK for CRW web scraper — scrape, crawl, and map any website from Python

crw

Python SDK for CRW — the open-source web scraper built for AI agents.

Install

# One-line install (auto-detects OS & arch):
curl -fsSL https://raw.githubusercontent.com/us/crw/main/install.sh | sh

# npm (zero install):
npx crw-mcp

# Python:
pip install crw

# Cargo:
cargo install crw-mcp

# Docker:
docker run -i ghcr.io/us/crw crw-mcp

CLI Usage

After installing, you can use crw-mcp as an MCP server for any AI coding agent:

# Start the MCP stdio server
crw-mcp

# Add to Claude Code
claude mcp add crw -- npx crw-mcp

MCP client config (works with Cursor, Windsurf, Cline, Claude Desktop, etc.):

{
  "mcpServers": {
    "crw": {
      "command": "npx",
      "args": ["crw-mcp"]
    }
  }
}

SDK Usage

from crw import CrwClient

# Zero-config (downloads crw-mcp binary automatically):
client = CrwClient()
result = client.scrape("https://example.com")
print(result["markdown"])

# Or connect to a remote server:
client = CrwClient(api_url="https://fastcrw.com/api", api_key="fc-...")

# Scrape with options:
result = client.scrape("https://example.com", formats=["markdown", "links"])
print(result["markdown"])
print(result["links"])

# Crawl a site:
job = client.crawl("https://example.com", max_depth=2, max_pages=10)
print(job["id"])

# Map all URLs on a site:
urls = client.map("https://example.com")
print(urls)

Search (Cloud Only)

Search requires a cloud API connection — it's not available in subprocess mode.

from crw import CrwClient

client = CrwClient(api_url="https://fastcrw.com/api", api_key="YOUR_KEY")

# Basic search
results = client.search("web scraping tools 2026")

# Search with options
results = client.search(
    "AI news",
    limit=10,
    sources=["web", "news"],
    tbs="qdr:w",
)

# Search + scrape content
results = client.search(
    "python tutorials",
    scrape_options={"formats": ["markdown"]},
)

Note: Search is a cloud-only feature. Calling search() without api_url raises CrwError.
