**Core Engine** (`lib/core/`): MCP server, tools, caching, HTTP client, validation - **Adapters** (`lib/adapters/`): CLI (stdio), Cloudflare Workers, Smithery deployment - **Configuration** (`lib/config/`): Environment-based config with `.mcprc.json` support - **Types** (`lib/types/`): TypeScript interfaces and type definitions ### Key Features Highlighted - 🔄 **Request Deduplication**: Prevents concurrent identical API calls - ⚡ **Circuit Breaker**: Automatic failure protection with 30s recovery - 💾 **Smart Caching**: LRU cache with TTL and automatic cleanup - 📊 **Built-in Metrics**: Request tracking, cache hits, error rates - 🔧 **Configurable APIs**: Support for custom CNPJ/CEP endpoints - 🔐 **Authentication**: Flexible header-based auth for custom APIs ## 🔧 Configuration Enhancements ### Environment Variables - Added comprehensive list of all available environment variables - Documented default values and behavior - Added transport configuration options - Enhanced authentication options ### Configuration File Support - Updated `.mcprc.json` schema documentation - Explained configuration hierarchy and priority - Added examples for different use cases ## 🚀 Deployment Options ### Multiple Deployment Methods - **NPM Package**: Global installation with `npx` command - **Local Build**: Traditional build and run approach - **Cloudflare Workers**: Serverless deployment with global edge performance - **Smithery**: Marketplace deployment option ### Transport Modes - **stdio**: Default mode for CLI tools and desktop applications - **HTTP**: Web-compatible mode with CORS support and health endpoints ## 📊 Performance Features ### Built-in Optimizations - Request deduplication to prevent redundant API calls - Circuit breaker pattern for API resilience -
