cxxmcp vs swift-mcp

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.; swift-mcp: Swift MCP extends the official, incomplete Swift SDK for the Model Context Protocol, providing a robust implementation of most features from protocol version 2025-11-25. It also addresses critical bugs and compliance issues found in the original SDK, offering comprehensive guides for both client and server development.
