Web Browsing Skill

Automatic fallback mechanism for web research.

CRITICAL: Tool Availability

NEVER check mcps folder to verify tool existence. Tools are ALWAYS available - just call them directly:
  • WebFetch
    - Cursor built-in fetch tool (fastest)
  • cursor-browser-extension
    - Cursor built-in browser
  • user-chrome-devtools
    - Chrome DevTools (alternative)

Fallback Chain

1. WebFetch (fast, preferred)
   ↓ fails/error
2. Browser MCP (cursor-browser-extension)
   ↓ captcha/block
3. ai_interaction (request user help)

Step 1: WebFetch (Default)

WebFetch url="https://example.com"
Continue to Step 2 if:
  • HTTP error (4xx, 5xx)
  • Content empty or truncated
  • Authentication required
  • Rate limited

Step 2: Browser MCP

Use 
cursor-browser-extension
MCP tools directly:
1. browser_navigate → target URL
2. browser_snapshot → get page content
3. browser_take_screenshot → visual reference (if needed)
Alternative: 
user-chrome-devtools
if cursor-browser-extension fails.
Continue to Step 3 if:
  • Captcha detected
  • Bot check / "verify you're human"
  • Login required
  • Cloudflare/DDoS protection
  • Page content not loading

Step 3: User Assistance

CRITICAL RULES:
  • NEVER make autonomous decisions (e.g., switching to DuckDuckGo when Google blocked)
  • NEVER bypass user by trying alternative search engines/sites without asking
  • ALWAYS inform user and wait for instruction via ai_interaction
Call 
ai_interaction
tool with message:
"Browser bị chặn bởi [captcha/bot check/login].
URL: [url]
Cần bạn:
1. Mở browser manual
2. Bypass protection
3. Báo lại khi xong để tôi tiếp tục

Hoặc bạn muốn thử [alternative option]?"
Then wait for user confirmation via ai_interaction before retrying.

Detection Patterns

Captcha/Block Indicators

  • "verify you are human"
  • "captcha"
  • "cloudflare"
  • "access denied"
  • "please wait while we verify"
  • Blank page with only scripts
  • HTTP 403, 429, 503

Success Indicators

  • Meaningful content returned
  • Expected HTML structure
  • No error messages

Best Practices

  1. Always try WebFetch first - fastest option
  2. Check response quality - not just HTTP status
  3. Don't spam retries - wait between attempts
  4. Be transparent - tell user what's happening
  5. Save useful content - don't re-fetch unnecessarily

Integration with ai_interaction

When user helps bypass protection:
  1. User completes manual action
  2. User responds via ai_interaction
  3. Agent retries with Browser MCP (cookies preserved)
  4. Continue with research
