## [Unreleased]

## [0.1.0-alpha1] - 2025-08-02

### Added - Initial MCP CVE Intelligence Server Lite Alpha

> **Note**: This is the **first alpha release** of the MCP CVE Intelligence Server **Lite**, providing core CVE intelligence capabilities through the Model Context Protocol. This lite version focuses on essential features with streamlined functionality. This alpha version is feature-complete but may undergo API refinements before the stable 1.0 release.

#### Core CVE Intelligence Features (7 MCP Tools - Lite Version)

- **Advanced CVE Search** (`searchCves`): Multi-source CVE data aggregation with comprehensive filtering and intelligent date-based recommendations
- **Detailed CVE Information** (`getCveDetails`): Full CVSS v4/v3/v2 metrics, affected products, and exploit references
- **Trending Analysis** (`getTrendingCves`): CVE trending based on severity, age, and exploit indicators with intelligent scoring
- **EPSS Risk Scoring** (`calculateEpssScores`): Environmental context-aware vulnerability prioritization with exploit prediction
- **Professional Reports** (`generateCveReport`): Technical penetration testing reports in multiple formats (Markdown, JSON, summary)
- **Product Discovery** (`searchByCpe`): CPE-based vulnerability discovery for specific products and versions
- **Health Monitoring** (`getSourceHealth`): Data source availability, performance tracking, and status diagnostics

#### CVE Data Sources (3 Implemented - Lite Configuration)

- **NVD (National Vulnerability Database)**: Primary CVE data source with CVSS metrics and CPE matching
- **MITRE CVE Records**: Authoritative CVE information with official assignments and CWE mappings  
- **GitHub Security Advisories**: Modern vulnerability advisories with ecosystem-specific data

#### Exploit Intelligence System (Lite Pattern Detection)

- **Pattern-Based Detection**: Automatic detection from CVE references using streamlined pattern matching
- **Essential Coverage**: Support for Exploit-DB, Metasploit, PacketStorm, GitHub PoCs, Nuclei, and Nmap
- **Intelligence Analysis**: Intelligent parsing of CVE references with verification and context
- **Performance Optimized**: Pre-calculated exploit indicators during data normalization for fast access

#### Enterprise-Ready Features (Lite Edition)

- **Dual Transport Support**: HTTP REST API mode and MCP stdio transport for flexible integration
- **Health Monitoring**: Essential endpoints with source diagnostics
- **Performance Optimized**: Built-in timing metrics and intelligent caching
- **Flexible Authentication**: Multi-API key support with automatic fallback and rate limit management
- **Docker Ready**: Containerization with multi-stage builds and health checks
- **Security Hardened**: Non-root containers, input sanitization, and secure error handling

#### Technical Foundation

- **TypeScript Excellence**: Fully typed codebase with strict mode, comprehensive error handling, and modern ES modules
- **Robust Error Handling**: Exponential backoff retry logic, intelligent failure recovery, and graceful degradation
- **Configuration Management**: Flexible multi-source configuration via `cve-sources.json` with hot-reload support
- **Structured Logging**: Winston-based logging with performance timing, context tracking, and multiple output formats
- **Comprehensive Validation**: Zod schema validation for all inputs with detailed error reporting and sanitization

#### Documentation & Community

- **Complete Documentation**: Comprehensive README with setup guides and usage examples
- **Contributing Guidelines**: Detailed development workflow and contribution standards
- **Security Policy**: Vulnerability reporting procedures and security best practices
- **MIT License**: Open source licensing for broad compatibility and community adoption
- **Code Quality**: ESLint configuration with TypeScript best practices and automated checks

### Known Limitations (Lite Alpha Release)

- **Lite Version**: This is a streamlined lite edition focused on core CVE intelligence features
- **Alpha Version**: This is an alpha release - APIs may change before stable release
- **In-Memory Processing**: No persistent data storage in this lite version
- **Essential Pattern Detection**: Exploit detection uses reference pattern matching (no active scanning)
- **Public APIs Only**: Uses free/public APIs with rate limiting considerations

### Future Enhancements (Beyond Lite Version)

- Full enterprise edition with advanced exploit classification
- Real-time vulnerability monitoring and alerting
- Premium vulnerability database integrations
- Advanced threat intelligence correlation
- Persistent data storage and caching mechanisms
- Enhanced weaponization classification system
- Extended pattern detection capabilities

### Contributing

We welcome contributions! This lite release provides a solid foundation for expanding CVE intelligence capabilities. Priority areas for contribution include:

- Adding additional CVE and exploit data sources  
- Enhancing exploit detection and classification algorithms
- Improving performance optimization and caching mechanisms
- Expanding report formats and visualization options
