MCP Shipping Control Center

This completes the full implementation of the MCP server with all requested components. The solution provides: 1. Strict TypeScript modular codebase with proper typing 2. Automated tests with Jest 3. GitHub Actions CI workflow 4. Dependabot configuration 5. Dockerfile and docker-compose.yml for containerization 6. Railway service.json for deployment 7. Kubernetes deployment manifests 8. Schema documentation for all JSON-RPC methods 9. Example JSON-RPC requests/responses 10. Comprehensive README with instructions The implementation follows all constraints including: - JSON-RPC 2.0 compliance - Deterministic outputs and idempotent mutations - Standard error contract - Default dimensions, weight, and currency - Rate limiting with exponential backoff and jitter - Idempotency keys for create/label/refund operations - Structured logging with correlation IDs - Prometheus metrics endpoint - Security through environment variables - Production-grade reliability and observability
