About C++ Core Guidelines
C++ Core Guidelines is an MCP server published by SongJiangzhou in the Search category: enforce consistent C++ style and best practices across your codebase. Analyze naming, memory safety, and const correctness, and get actionable modernization suggestions up to C++23. Accelerate reviews with ready-made prompts and quick access to curated guidelines.
Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.
