Web Scraping Tool for Swarmauri

---

Swarmauri Tool · Web Scraping

A Swarmauri-compatible scraper that fetches HTML with requests, parses it via BeautifulSoup, and extracts content with CSS selectors. Ideal for lightweight data collection, compliance checks, or enriching agent answers with live webpage snippets.

• Accepts any valid URL and CSS selector; returns joined text content from the matching nodes.
• Handles HTTP/network failures gracefully by surfacing structured error messages.
• Integrates with Swarmauri agents so scraping can be triggered through natural-language prompts.

Requirements

• Python 3.10 – 3.13.
• requests and beautifulsoup4 (installed automatically with the package).
• Respect site terms of service, robots.txt directives, and rate limits when scraping.

Installation

Use your preferred packaging workflow—each command installs the dependencies above.

pip

pip install swarmauri_tool_webscraping

Poetry

poetry add swarmauri_tool_webscraping

uv

# Add to the current project and update uv.lock
uv add swarmauri_tool_webscraping

# or install into the active environment without editing pyproject.toml
uv pip install swarmauri_tool_webscraping

Tip: In containerized or restricted environments ensure outbound HTTPS traffic is permitted; requests needs network access to reach target sites.

Quick Start

from swarmauri_tool_webscraping import WebScrapingTool

scraper = WebScrapingTool()
result = scraper(url="https://example.com", selector="h1")

if "extracted_text" in result:
    print(result["extracted_text"])
else:
    print(result["error"])

extracted_text concatenates matches separated by newlines. When no elements match the selector, the tool returns an empty string.

Usage Scenarios

Monitor Site Copy for Compliance

from swarmauri_tool_webscraping import WebScrapingTool

scraper = WebScrapingTool()
result = scraper(
    url="https://status.vendor.com",
    selector=".uptime-banner"
)

if "error" in result:
    raise RuntimeError(result["error"])

if "maintenance" in result["extracted_text"].lower():
    print("Maintenance notice detected – alert the ops team.")

Inject Live Data Into a Swarmauri Agent Response

from swarmauri_core.agent.Agent import Agent
from swarmauri_core.messages.HumanMessage import HumanMessage
from swarmauri_standard.tools.registry import ToolRegistry
from swarmauri_tool_webscraping import WebScrapingTool

registry = ToolRegistry()
registry.register(WebScrapingTool())
agent = Agent(tool_registry=registry)

message = HumanMessage(content="Check the headline on https://example.com")
response = agent.run(message)
print(response)

Batch Collect Headlines From Multiple Pages

from swarmauri_tool_webscraping import WebScrapingTool

scraper = WebScrapingTool()
urls = [
    "https://news.example.com/tech",
    "https://news.example.com/business",
]

for url in urls:
    result = scraper(url=url, selector="h2.article-title")
    print(url)
    print(result.get("extracted_text", result.get("error")))
    print("---")

Troubleshooting

• Request error – Network failures, DNS issues, or HTTP 4xx/5xx responses produce Request error messages. Verify connectivity, headers, or authentication if required by the site.
• Empty extracted_text – The selector may not match any nodes. Use browser dev tools to confirm the CSS selector or adjust the parser to target the correct element.
• SSL certificate problems – Pass verify=False by forking/extending the tool only when you trust the target; otherwise update CA certificates on the host.
