- **@context-pods/server** (95%+ coverage): Meta-MCP Server with tools, registry management, and protocol handling
- **@context-pods/testing** (95%+ coverage): Comprehensive testing framework for MCP protocol compliance and script wrapper validation
- **@context-pods/templates** (85%+ coverage): Template validation, management, and multi-language support
- **@context-pods/create** (75%+ coverage): NPX runner for seamless installation and setup
### 2. Templates
Templates are sophisticated blueprints for generating production-ready MCP servers:
- **Multi-Language Support**: TypeScript, Python, Rust, and Shell templates
- **Variable System**: Advanced Handlebars-style templating with validation
- **Template Metadata**: Rich `template.json` files with dependencies, scripts, and MCP configuration
- **Optimization Features**: TurboRepo integration, hot reload, shared dependencies, and build caching
- **Built-in Templates**: Five production-ready templates covering different use cases and complexity levels
- **Template Validation**: Comprehensive validation system ensuring template integrity and MCP compliance
### 3. Meta-MCP Server
The Meta-MCP Server exposes Context-Pods functionality through the MCP protocol itself:
- **MCP Tools**: `create-mcp`, `wrap-script`, `list-mcps`, `validate-mcp`
- **Server Registry**: SQLite-based registry for managing generated servers
- **Protocol Compliance**: Full MCP 2024-11-05 protocol implementation
- **Claude Desktop Integration**: Seamless integration with Claude Desktop configuration
- **Development Workflow**: Built-in development server with hot reload and debugging
### 4. Testing Framework
Comprehensive testing capabilities for MCP server validation:
- **Protocol Compliance**: Validates against official MCP schemas using Zod
- **Script Wrapper Testing**: Multi-language script testing (Python, TypeScript, Rust, Shell)
- **Performance Benchmarking**: Load testing and performance analysis
- **Integration Testing**: End-to-end server communication testing
- **Report Generation**: HTML and JUnit XML reports for CI/CD integration
## Build System
### TurboRepo Optimization
- **Intelligent Caching**: Build and test results are cached for maximum performance
- **Parallel Execution**: Tasks run in parallel across packages when possible
- **Dependency Awareness**: Only rebuilds packages when their dependencies change
- **Remote Caching**: Support for shared caches across development teams
### TypeScript Configuration
- **Composite Projects**: Uses TypeScript project references for efficient incremental builds
- **Strict Mode**: Enforces strict type safety across all packages
- **ES Modules**: Modern JavaScript modules (ESM) with proper import/export patterns
- **Path Mapping**: Simplified imports between packages using TypeScript path mapping
### npm Workspaces + TurboRepo
Combined benefits:
- **Dependency Hoisting**: Shared dependencies optimized at root level
- **Cross-Package Development**: Live development with automatic rebuilds
- **Unified Commands**: Single commands orchestrate complex multi-package operations
- **Build Optimization**: Incremental builds with intelligent change detection
- **Testing Integration**: Coordinated test execution with coverage aggregation
### Build Scripts
Optimized root-level scripts:
- `npm run build`: TurboRepo-optimized parallel builds
- `npm run test`: Comprehensive test suite with coverage reporting
- `npm run lint`: ESLint with auto-fixing across all packages
- `npm run format`: Prettier formatting with consistent style
- `npm run dev`: Development mode with hot reload and file watching
- `npm run clean`: Clean all build artifacts and caches
