MCP Design Patterns: 6 Essential Architectures for AI Integration (Beginner to Enterprise)

Master the 6 essential MCP (Model Context Protocol) design patterns for building AI-integrated systems. Learn when to use each pattern and how to architect scalable AI solutions.

🎯 6 PATTERNS COVERED:
1. Direct API Wrapper - Quick integrations with stable APIs
2. Composite Service - Orchestrating multiple APIs for complex workflows
3. MCP-to-Agent - AI agents invoking specialized AI agents
4. Event-Driven Integration - Async processing for non-blocking workflows
5. Hierarchical MCP - Enterprise-scale domain-driven architecture
6. Local Resource Access - High-performance file system operations

⭐ COMPLEXITY RATINGS:
Direct API Wrapper: ⭐ (Low)
Composite Service: ⭐⭐⭐ (Medium)
MCP-to-Agent: ⭐⭐⭐⭐ (High)
Event-Driven: ⭐⭐⭐ (Medium)
Hierarchical: ⭐⭐⭐⭐⭐ (Very High)
Local Resource: ⭐⭐ (Low-Medium)
