cxxmcp vs ruby-sdk

cxxmcp: cxxmcp is a production-ready C++17 SDK for the Model Context Protocol (MCP), enabling the creation of MCP servers and clients that integrate directly into native C++ applications. It offers full protocol coverage and robust cross-SDK conformance validation, ensuring reliability and compatibility.; 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.
