MCP Web Scrape is designed with security and responsible web scraping practices at its core. We prioritize:

• Robots.txt compliance - respecting website policies
• Rate limiting - preventing server overload
• No paywall bypass - ethical content access only
• Safe content handling - preventing XSS and injection attacks
• Privacy protection - no sensitive data logging

• Always checks robots.txt before scraping
• Respects disallow rules for the configured user agent
• Honors crawl delays specified in robots.txt
• Fails safely if robots.txt cannot be accessed

// Example: Automatic robots.txt validation
const isAllowed = await checkRobotsTxt(url, 'mcp-web-scrape');
if (!isAllowed) {
  throw new McpError(ErrorCode.InvalidRequest, 'Robots.txt disallows access');
}

• Per-domain rate limits (default: 1 request/second)
• Configurable delays between requests
• Exponential backoff on rate limit errors
• Respect server response headers (Retry-After, etc.)

• HTML sanitization during Markdown conversion
• URL validation to prevent SSRF attacks
• Content-Type checking before processing
• Size limits to prevent memory exhaustion

• No sensitive data logging (URLs may be logged for debugging)
• Local caching only - no external data transmission
• Configurable cache retention periods
• Cache encryption for sensitive content (optional)

We provide security updates for the following versions:

Please do NOT report security vulnerabilities through public GitHub issues.

1. Email: Send details to security@mcp-web-scrape.dev (if available)
2. GitHub Security Advisories: Use the private vulnerability reporting feature
3. Encrypted communication: PGP key available on request

Subject: [SECURITY] Vulnerability in MCP Web Scrape v1.2.3

## Summary
Brief description of the vulnerability

## Impact
- Confidentiality: [High/Medium/Low]
- Integrity: [High/Medium/Low] 
- Availability: [High/Medium/Low]

## Reproduction
1. Step one
2. Step two
3. Observe vulnerability

## Affected Versions
- Version X.Y.Z through A.B.C

## Suggested Mitigation
Your ideas for fixing the issue

## Disclosure Timeline
Preferred timeline for coordinated disclosure

• Acknowledgment: Within 24 hours of report
• Initial assessment: Within 72 hours
• Regular updates: Every 7 days until resolution
• Coordinated disclosure: Work with reporter on timeline

1. Day 0: Vulnerability reported
2. Day 1: Acknowledgment sent
3. Day 3: Initial assessment and severity rating
4. Day 7: Fix development begins (for confirmed issues)
5. Day 14-30: Patch release (depending on severity)
6. Day 30-90: Public disclosure (coordinated with reporter)

• Critical: Remote code execution, data exfiltration
• High: Privilege escalation, authentication bypass
• Medium: Information disclosure, DoS attacks
• Low: Minor information leaks, configuration issues

When running the HTTP server, we recommend these headers:

// Express.js example
app.use((req, res, next) => {
  res.setHeader('X-Content-Type-Options', 'nosniff');
  res.setHeader('X-Frame-Options', 'DENY');
  res.setHeader('X-XSS-Protection', '1; mode=block');
  res.setHeader('Strict-Transport-Security', 'max-age=31536000');
  next();
});

The following are generally not considered security vulnerabilities:

• Rate limiting bypasses using multiple IPs/proxies
• Robots.txt violations when explicitly configured to ignore
• Content extraction from public, non-paywalled content
• Performance issues that don't lead to DoS
• Social engineering attacks against users
• Physical access to systems running MCP Web Scrape

• OWASP Web Scraping Security
• Responsible Web Scraping
• Robots.txt Specification

• Static analysis: ESLint security rules
• Dependency scanning: npm audit, Snyk
• Runtime protection: Helmet.js for HTTP servers
• Monitoring: Application security monitoring

• Security Email: security@mcp-web-scrape.dev (if available)
• GitHub Security: Private vulnerability reporting
