java-sdk vs ruby-sdk

java-sdk: The MCP Java SDK provides a robust set of projects enabling Java applications to seamlessly interact with AI models and tools using the Model Context Protocol. It offers a standardized interface that supports both synchronous and asynchronous communication patterns for flexible development.; ruby-sdk: The MCP Ruby SDK provides official support for building and interacting with Model Context Protocol servers and clients. It offers a comprehensive set of features including JSON-RPC handling, tool/prompt/resource management, and various transport layers, facilitating the integration of LLM-powered applications.
