v1.6.4

🚀 Embedded Transport Implementation

This release introduces a complete embedded transport implementation for zero-overhead in-process MCP communication.

✨ New Features

• Embedded Transport: Direct in-process communication using Go channels with no serialization overhead
• Client Integration: New WithEmbedded() option for seamless client configuration
• Server Integration: New AsEmbedded() method following the same pattern as other transports
• Full MCP Protocol Support: Complete bidirectional communication for all MCP operations

🔧 Implementation Details

• Thread-safe concurrent operations using atomic operations and sync.Map
• Proper JSON-RPC 2.0 message handling and notification routing
• Clean channel-based architecture eliminating mutex usage
• Comprehensive integration tests covering tools, resources, prompts, and sampling

📚 Examples

• Complete embedded transport example demonstrating all MCP capabilities
• Integration tests showing concurrent operations and notification handling

🎯 Use Cases

Perfect for:

• Library integration scenarios
• Testing and development environments
• High-performance in-process MCP communication
• Scenarios where network overhead should be eliminated

🧪 Testing

• All existing tests continue to pass
• New comprehensive integration tests added
• Example application demonstrates full functionality

This embedded transport provides the fastest possible MCP communication method while maintaining full protocol compatibility.
