AutoGen agents doing web research hit a common wall: Cloudflare-protected sites return 403s or empty content. Standard HTTP fetchers don't work on ~60% of high-value web targets.

Root Cause

AutoGen agents doing web research hit a common wall: Cloudflare-protected sites return 403s or empty content. Standard HTTP fetchers don't work on ~60% of high-value web targets.

Code Example

{
  "mcpServers": {
    "anybrowse": {
      "type": "streamable-http",
      "url": "https://anybrowse.dev/mcp"
    }
  }
}

Context

AutoGen agents doing web research hit a common wall: Cloudflare-protected sites return 403s or empty content. Standard HTTP fetchers don't work on ~60% of high-value web targets.

Suggestion

anybrowse is an MCP server that handles this natively -- it runs real residential Chrome to bypass bot detection and returns clean markdown ready for LLM context.

Add to your AutoGen + MCP setup:

{
  "mcpServers": {
    "anybrowse": {
      "type": "streamable-http",
      "url": "https://anybrowse.dev/mcp"
    }
  }
}

Then your agents can call scrape, search, and extract tools on any site including Cloudflare-protected ones.

Why this matters for AutoGen

  • Research agents can reliably retrieve from news sites, LinkedIn, Amazon, and gov sites
  • extract tool returns structured JSON from any page (price, title, in-stock etc.)
  • batch_scrape handles up to 10 URLs in parallel -- good for research tasks
  • Free tier requires no API key, so agents can use it out of the box

Fix Plan

To resolve the issue of AutoGen agents being blocked by Cloudflare-protected sites, integrate the anybrowse MCP server into your setup. Here are the steps:

  • Add the anybrowse MCP server configuration to your AutoGen setup:
{
  "mcpServers": {
    "anybrowse": {
      "type": "streamable-http",
      "url": "https://anybrowse.dev/mcp"
    }
  }
}
  • Update your agents to use the scrape, search, and extract tools provided by anybrowse.
  • For example, to scrape a Cloudflare-protected site, use the scrape tool:
import requests

url = "https://example.com"  # Cloudflare-protected site
response = requests.post("https://anybrowse.dev/mcp/scrape", json={"url": url})
print(response.json())
  • To extract structured data from a page, use the extract tool:
import requests

url = "https://example.com"  # Cloudflare-protected site
response = requests.post("https://anybrowse.dev/mcp/extract", json={"url": url})
print(response.json())

Verification

To verify that the fix worked, test your agents with Cloudflare-protected sites and check that they can successfully retrieve content and extract data.

Extra Tips

  • Make sure to check the anybrowse documentation for usage limits and requirements: https://anybrowse.dev/docs
  • Consider using the batch_scrape tool for parallel scraping of multiple URLs.
