cxxmcp vs kotlin-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.; kotlin-sdk: This Kotlin SDK implements the Model Context Protocol (MCP), offering a standardized way for applications to provide context to LLMs, separating context provision from LLM interaction. It simplifies building MCP clients and servers, supporting various Kotlin platforms and standard communication transports.
