## 🎯 **Core Design Principles**

KGraph-MCP is built on these foundational principles:

### **1. Knowledge-Driven Architecture**
- Semantic representation of MCP primitives
- Graph-based tool discovery and orchestration
- Intelligent tool selection and routing

### **2. Agent-Based Autonomy**
- Specialized AI agents for different functions
- Self-orchestrating tool networks
- Autonomous task planning and execution

### **3. Modular & Extensible**
- Plugin-based architecture
- Clean separation of concerns
- Easy integration with existing MCP servers

### **4. Performance & Scalability**
- Efficient graph operations
- Asynchronous processing
- Horizontal scaling capabilities

## 📋 **Architecture Patterns**

- **Event-Driven Architecture** - Asynchronous event processing
- **Microservices Pattern** - Loosely coupled, independently deployable services
- **Repository Pattern** - Data access abstraction
- **Strategy Pattern** - Pluggable algorithms and behaviors
- **Observer Pattern** - Real-time status updates and monitoring

## 🔗 **Integration Points**

- **MCP Protocol** - Model Context Protocol compliance
- **RESTful APIs** - HTTP-based external integrations
- **WebSocket** - Real-time bidirectional communication
- **Graph Databases** - Native graph storage and querying
- **Vector Databases** - Semantic search and similarity
