Which integrations are available for this server?

Provides C++ code analysis tools for checking naming conventions, include guards, memory safety, const correctness, and modern C++ upgrade suggestions, along with access to C++ style guide documentation and best practices.

How do I use C++ Style Guide MCP Server?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@C++ Style Guide MCP Server check this code for memory safety issues" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

C++ Style Guide 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 and quick access to curated guidelines.

Tools

Tool	Description
`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

Resources

URI	Description
`cpp-style://naming/{category}`	Naming convention reference (variable, class, function, namespace, …)
`cpp-style://best-practices/{topic}`	Best practice guides (memory, exceptions, templates, concurrency, …)
`cpp-style://standard/{version}`	C++ standard feature docs (cpp11 – cpp23)
`cpp-style://examples/{pattern}`	Design pattern examples (RAII, Pimpl, Factory, Observer, …)

Prompts

Prompt	Description
`code_review`	Code review template (general / performance / safety / readability / modern)
`refactor_suggestion`	Refactoring guide targeting a specific C++ standard

Usage

Connect via Smithery (recommended)

npx -y @smithery/cli install @SongJiangzhou/cpp_guidelines --client claude

MCP endpoint (HTTP / streamable-http)

Local installation

git clone https://github.com/SongJiangzhou/cpp_guidelines_mcp.git
cd cpp_guidelines_mcp
uv sync
uv run mcp run cpp_style_server.py

Add to your MCP client config:

{
  "mcpServers": {
    "cpp-style": {
      "command": "uv",
      "args": ["run", "mcp", "run", "cpp_style_server.py"],
      "cwd": "/path/to/cpp_guidelines_mcp"
    }
  }
}

Examples

# Check a variable name
check_naming("myVariable", "variable")

# Analyze memory safety
analyze_memory_safety("void f(int* p) { delete p; p->run(); }")

# Modernize code to C++17
suggest_modern_cpp("for (int i=0; i<v.size(); i++) {...}", "cpp17")

# Check const correctness
check_const_correctness("class Foo { int getValue() { return x; } int x; };")
