Superstore MCP Server

# Security Guide for Superstore MCP This document outlines security considerations, best practices, and implementation details for the Superstore MCP server. ## Security Overview The Superstore MCP server implements multiple layers of security to protect user credentials, maintain session integrity, and ensure safe operation. ## Authentication Security ### Credential Management #### Environment Variable Storage - **Method**: Credentials stored in environment variables only - **Location**: `SUPERSTORE_EMAIL` and `SUPERSTORE_PASSWORD` in `mcp.json` - **Protection**: Never logged, never stored in code, never transmitted ```json { "superstore-mcp": { "env": { "SUPERSTORE_EMAIL": "your-email@example.com", "SUPERSTORE_PASSWORD": "your-secure-password" } } } ``` #### Best Practices 1. **Strong Passwords**: Use complex, unique passwords for your Superstore account 2. **Regular Rotation**: Change passwords periodically 3. **Secure Storage**: Protect your `mcp.json` file with appropriate file permissions 4. **No Hardcoding**: Never hardcode credentials in source code ### Session Security #### Cookie Management - **Secure Storage**: Cookies stored in memory only, never persisted to disk - **Automatic Cleanup**: Sessions cleaned up on logout or timeout - **Isolation**: Each MCP server instance has isolated sessions #### Session Timeout - **Default**: 1 hour session timeout - **Configurable**: Set via `SESSION_TIMEOUT` environment variable - **Automatic Refresh**: Sessions refreshed before expiry ## Network Security ### Stealth Mode The system uses `puppeteer-extra-plugin-stealth` to: - Avoid detection as automated browser - Mimic real user behavior - Use realistic headers and fingerprints - Implement human-like delays ### Request Headers ```typescript { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36', 'Accept-Language': 'en-US,en;q=0.9', 'Accept-Encoding': 'gzip, deflate, br', 'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9', 'Cache-Control': 'no-cache', 'Pragma': 'no-cache' } ``` ### Rate Limiting - **Built-in Delays**: Human-like delays between requests - **Exponential Backoff**: Increasing delays on failures - **Jitter**: Random variation to avoid patterns - **Circuit Breaker**: Prevents cascading failures ## Data Protection ### No Persistent Storage - No credentials stored on disk - No session data persisted - No cache data contains sensitive information - All data exists only in memory during operation ### Data Validation - **Input Sanitization**: All inputs validated and sanitized - **Type Safety**: TypeScript ensures type safety - **Schema Validation**: Zod schemas validate all data structures ### Error Handling - **No Information Leakage**: Error messages don't expose sensitive data - **Secure Logging**: Credentials never logged - **Graceful Degradation**: System fails securely ## Browser Security ### Headless Browser Configuration ```typescript { headless: 'new', args: [ '--no-sandbox', '--disable-setuid-sandbox', '--disable-dev-shm-usage', '--disable-accelerated-2d-canvas', '--no-first-run', '--no-zygote', '--disable-gpu', '--disable-background-timer-throttling', '--disable-backgrounding-occluded-windows', '--disable-renderer-backgrounding' ] } ``` ### Security Features - **Sandboxing**: Browser runs in sandboxed environment - **Resource Limits**: Limited system resource usage - **Process Isolation**: Browser processes isolated from main application ## Operational Security ### Monitoring and Logging #### What is Logged - Authentication attempts (success/failure, no credentials) - Session lifecycle events - Error conditions (without sensitive data) - Performance metrics #### What is NOT Logged - Passwords or credentials - Session cookies - Personal information - Sensitive order data #### Log Example ``` [INFO] Authentication attempt started [INFO] Session created successfully [ERROR] Network timeout after 3 retries [INFO] Session expired, refreshing... ``` ### Error Handling Security #### Secure Error Messages ```typescript // Good - No sensitive data throw new Error("Authentication failed: Invalid credentials"); // Bad - Exposes sensitive data throw new Error('Authentication failed: Password "secret123" is incorrect'); ``` #### Error Context - **Operation**: What operation failed - **Attempt**: Which attempt failed - **Timestamp**: When the error occurred - **No Sensitive Data**: Never include credentials or personal data ## Configuration Security ### MCP Configuration ```json { "superstore-mcp": { "command": "node", "args": ["/path/to/dist/index.js"], "env": { "NODE_ENV": "production", "SUPERSTORE_EMAIL": "user@example.com", "SUPERSTORE_PASSWORD": "secure-password", "SESSION_TIMEOUT": "3600000" } } } ``` ### File Permissions ```bash # Secure the MCP configuration file chmod 600 ~/.cursor/mcp.json # Ensure only owner can read/write chown $USER:$USER ~/.cursor/mcp.json ``` ### Environment Isolation - **Process Isolation**: Each MCP server runs in isolated process - **Memory Isolation**: No shared memory between instances - **Network Isolation**: Each instance has independent network state ## Threat Mitigation ### Common Threats #### 1. Credential Theft **Mitigation**: - No credential storage - Environment variable protection - Secure file permissions - Regular credential rotation #### 2. Session Hijacking **Mitigation**: - Secure cookie handling - Session timeout enforcement - Automatic session cleanup - No persistent session storage #### 3. Man-in-the-Middle Attacks **Mitigation**: - HTTPS-only communication - Certificate validation - Secure headers - No credential transmission #### 4. Automated Detection **Mitigation**: - Stealth mode operation - Human-like behavior simulation - Rate limiting - Realistic browser fingerprinting ### Security Monitoring #### Indicators of Compromise - Unusual authentication patterns - Unexpected session timeouts - High error rates - Unusual network traffic #### Response Procedures 1. **Immediate**: Revoke session and require re-authentication 2. **Investigation**: Check logs for suspicious activity 3. **Recovery**: Reset credentials if necessary 4. **Prevention**: Update security measures ## Compliance and Privacy ### Data Privacy - **Minimal Data Collection**: Only necessary data is collected - **No Personal Data Storage**: No personal information persisted - **Temporary Processing**: Data processed in memory only - **Automatic Cleanup**: All data cleaned up on session end ### GDPR Compliance - **Data Minimization**: Only collect necessary data - **Purpose Limitation**: Data used only for intended purpose - **Storage Limitation**: No long-term data storage - **Right to Erasure**: Automatic cleanup provides data deletion ### Terms of Service Compliance - **Respectful Usage**: Rate limiting prevents server overload - **Authorized Access**: Only access user's own account - **No Data Scraping**: Only access authorized account data - **Terms Compliance**: Follows Superstore's terms of service ## Security Best Practices ### For Users 1. **Strong Credentials** - Use unique, complex passwords - Enable 2FA on your Superstore account - Regular password rotation 2. **Secure Configuration** - Protect your `mcp.json` file - Use appropriate file permissions - Regular security updates 3. **Monitoring** - Monitor for unusual activity - Check session statistics regularly - Report suspicious behavior ### For Developers 1. **Code Security** - Never log credentials - Validate all inputs - Use secure coding practices - Regular security audits 2. **Dependency Management** - Keep dependencies updated - Monitor for security vulnerabilities - Use trusted packages only 3. **Testing** - Security testing included - Penetration testing recommended - Regular security reviews ## Incident Response ### Security Incident Procedure 1. **Detection** - Monitor logs and metrics - Automated alerts for anomalies - User reports of suspicious activity 2. **Response** - Immediate session termination - Credential reset if necessary - Investigation and analysis 3. **Recovery** - System restoration - Security measure updates - User notification if necessary 4. **Prevention** - Security measure improvements - Process updates - Training and awareness ### Contact Information For security issues: - Report via secure channels - Include detailed information - Provide logs if possible - Follow responsible disclosure ## Security Updates ### Regular Updates - **Dependencies**: Keep all packages updated - **Security Patches**: Apply security updates promptly - **Configuration**: Review and update security settings - **Monitoring**: Update monitoring and alerting ### Security Announcements - Monitor for security advisories - Subscribe to security mailing lists - Follow security best practices - Regular security training ## Conclusion The Superstore MCP server implements comprehensive security measures to protect user data and ensure safe operation.
