M6-4: Production Hardening & Quality Assurance

Overview

Implement comprehensive production hardening measures and quality assurance processes to ensure the MCP server meets enterprise security, reliability, and performance standards for production deployment.

Acceptance Criteria

Security Hardening

  • Implement input validation and sanitization for all endpoints
  • Add rate limiting and DDoS protection mechanisms
  • Implement request size limits and timeout protections
  • Add security headers and CORS policy configuration
  • Implement audit logging for all security-relevant events
  • Add secrets rotation and secure credential management
  • Implement principle of least privilege for all operations

Error Handling & Resilience

  • Implement comprehensive error handling with structured logging
  • Add circuit breaker patterns for external API calls
  • Implement retry logic with exponential backoff
  • Add graceful degradation for non-critical failures
  • Implement proper resource cleanup and connection pooling
  • Add health checks with dependency validation
  • Implement request timeout and cancellation handling

Quality Assurance Testing

  • Achieve ≥80% test coverage across all modules
  • Implement comprehensive integration test suite
  • Add load testing and stress testing scenarios
  • Create chaos engineering tests for failure scenarios
