- Implement MCP server with async/sync support and builder pattern configuration
- Add Server stdio/SSE transport layers with robust error handling
- Convert McpClient and McpServer to interfaces for better extensibility
- Add sampling capabilities for LLM interactions (text/image)
- Implement dynamic root management and runtime tool management
- Add comprehensive prompt and resource capabilities
- Add support for dynamic root management (add/remove roots at runtime)
Architecture Changes
- Introduce registration records for tools, resources, and prompts
- Improve thread safety with concurrent collections
- Enhance resource template handling
- Implement builder patterns for Server/Client capabilities
- Add support for server capabilities and implementation info
Transport Layer:

- Add StdioServerTransport for process-based communication
- Reorganize transport packages for better organization
- Improve transport error handling and shutdown processes
Documentation:
- Add detailed MCP reference documentation
- Include architecture diagrams and API documentation
- Add comprehensive test coverage for all components
- Include sample projects demonstrating stdio/SSE transports
BREAKING CHANGES:
Transport Package Reorganization
- Move StdioClientTransport to o.s.ai.mcp.client.transport
- Move SseClientTransport to o.s.ai.mcp.client.transport
- Move ServerParameters to o.s.ai.mcp.client.transport
- StdioClientTransport.errorHandler changed to private with
setter method Migration: Use setErrorHandler() method
instead of direct field access
API Changes
- Replace static factory methods with builder pattern
- Update ServerCapabilities to use builder pattern
- Make StdioClientTransport.errorHandler private with setter
- Replace rootsListProvider with direct root management
- Remove deprecated static factory methods
