What is the Cpp Guidelines MCP MCP server?

Enforce consistent C++ style and best practices across your codebase. Analyze naming conventions, memory safety, and const correctness, and get actionable modernization suggestions up to C++23. Accelerate reviews with ready-made prompts. Exposed over MCP by the cpp guidelines mcp mcp server, that capability becomes something an assistant can invoke while it works, not something you go and do afterwards.

Its toolset

Everything the assistant can do here goes through one of these:

  • check_naming — Validate C++ identifiers (variables, classes, functions, etc.) against naming conventions
  • check_include_guard — Verify header file include guards or #pragma once usage
  • analyze_memory_safety — Detect memory leaks, dangling pointers, and unsafe memory patterns
  • suggest_modern_cpp — Get modernization suggestions targeting C++11 through C++23
  • check_const_correctness — Find missing const qualifiers on member functions, parameters, and variables

Adding it to your client

The server ships on npm as @smithery/cli, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.

When to reach for it

This sits in the knowledge and memory group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Cpp Guidelines MCP's toolset — check_naming, check_include_guard, analyze_memory_safety and 2 more — is a fair guide to whether it matches your workflow. It is maintained by songjiangzhou; worth a glance at recent repository activity before you build anything load-bearing on it.

We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.

Caveats

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • MCP clients confirm each tool call by default. Leave that on until you have watched what the cpp guidelines mcp mcp server does with a few real requests.

Frequently asked questions

It connects Cpp Guidelines MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (check_naming, check_include_guard, analyze_memory_safety, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Cpp Guidelines MCP directly.
