Security Best Practices

Guidelines for implementing secure webMCP applications

API Security

Use HTTPS Everywhere

Always use HTTPS for all API communications

Configure TLS certificates and enforce HTTPS redirects

Implement Rate Limiting

Prevent abuse with configurable rate limits

Set per-user and per-IP rate limits based on usage patterns

Validate All Inputs

Sanitize and validate all user inputs

Use schema validation and input sanitization libraries

Authentication

Strong JWT Secrets

Use cryptographically secure secrets for JWT signing

Generate secrets with at least 256 bits of entropy

Token Expiration

Set appropriate token expiration times

Use short-lived access tokens with refresh token rotation

Secure Token Storage

Store tokens securely on client side

Use httpOnly cookies or secure storage mechanisms

Data Protection

Encrypt Sensitive Data

Encrypt PII and sensitive form data

Use field-level encryption for sensitive elements

Secure Key Management

Implement proper key rotation and storage

Use HSM or key management services for production

Data Minimization

Only collect and process necessary data

Implement data retention policies and automatic cleanup

Security Configuration Examples

Practical examples for implementing security features

Basic Security Configuration

Enable core security features

import { WebMCPProcessor } from '@webmcp/core';

const processor = new WebMCPProcessor({
  security: {
    // Enable CSRF protection
    enableCSRF: true,
    csrfTokenExpiry: 3600, // 1 hour
    
    // JWT configuration
    jwt: {
      secret: process.env.JWT_SECRET,
      expiresIn: '1h',
      scopes: ['webmcp:read', 'webmcp:write']
    },
    
    // Data encryption
    encryption: {
      method: 'jwe',
      algorithm: 'A256GCM',
      keyRotationInterval: 86400 // 24 hours
    },
    
    // Rate limiting
    rateLimit: {
      windowMs: 60000, // 1 minute
      maxRequests: 100,
      skipSuccessfulRequests: false
    }
  }
});

Advanced Security Setup

Production-ready security configuration

const securityConfig = {
  // HTTPS enforcement
  httpsOnly: true,
  hsts: {
    maxAge: 31536000, // 1 year
    includeSubDomains: true,
    preload: true
  },
  
  // Content Security Policy
  csp: {
    directives: {
      defaultSrc: ["'self'"],
      scriptSrc: ["'self'", "'unsafe-inline'"],
      styleSrc: ["'self'", "'unsafe-inline'"],
      imgSrc: ["'self'", "data:", "https:"]
    }
  },
  
  // Security headers
  headers: {
    'X-Frame-Options': 'DENY',
    'X-Content-Type-Options': 'nosniff',
    'X-XSS-Protection': '1; mode=block',
    'Referrer-Policy': 'strict-origin-when-cross-origin'
  },
  
  // Audit logging
  audit: {
    enabled: true,
    logLevel: 'info',
    sensitiveFields: ['password', 'ssn', 'creditCard'],
    retention: 90 // days
  }
};

const processor = new WebMCPProcessor({ security: securityConfig });
