- Add client and server-side logging capabilities with configurable severity levels
- Implement logging message notifications with DEBUG to EMERGENCY levels
- Add logging consumers for client-side log handling
- Update documentation with logging examples and configuration
- Add comprehensive tests for logging functionality
- Fix typo in README.md (notificaiotn -> notification)
- Centralize MCP method names as constants
- Move all JSON-RPC method names to McpSchema class as static constants
- Replace hardcoded method strings with constant references in McpAsyncClient
and McpAsyncServer
- Update test cases to use new method name constants
Resolves#35
- Reorganize McpAsyncServer code into logical sections (Lifecycle, Tool, Resource, Prompt Management)
- (bug) Fix resource registration to use URI instead of name as map key
- Improve error logging in StdioServerTransport with helper methods
- Clean up documentation and add transport mode descriptions
- Update sample server configuration with clearer method names and organization
- Replace bounded elastic schedulers with single thread executors
- Add timeouts to MCP server tests
- Enhance error handling in StdioServerTransport
- Comment out unused PaginatedRequest unmarshalling
- Simplify shutdown logic in StdioServerTransport
Removes custom stream injection capability from StdioServerTransport and
simplifies it to only use System.in/out.
Updates related tests to use System streams instead of piped streams.
- Add isClosing flag to coordinate graceful shutdown
- Synchronize output stream writes to prevent race conditions
- Enhance error handling in stream processing
- Add delay for pending message processing during shutdown
- Improve connection state tracking in tests
- 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:

- 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
Resolves #27,#25,#24,#11
Related to #12
