C++ Style Guide

You can connect to and run the C++ Style Guide MCP Server to enforce consistent C++ style, naming, memory safety, and modernization guidance across your projects. This MCP server offers a remote HTTP endpoint for queries and a local runtime you can start on your machine to interact with its analysis tools and prompts.

How to use

Use the MCP server to analyze C++ code, fetch naming and memory safety guidance, and receive modernization suggestions up to the latest C++ standards. You can access a remote MCP endpoint or run a local instance for interactive analysis. Use clear prompts to review code, request refactors, or verify const correctness.

How to install

Prerequisites: you need a working development environment with Python 3.12 or newer and the ability to run containerized or local MCP clients.

# Clone the MCP server repository
git clone https://github.com/SongJiangzhou/cpp_guidelines_mcp.git
cd cpp_guidelines_mcp

# Install runtime dependencies (example for a local Python-based server)
pip install -r requirements.txt

# Start a local MCP server process (runtime command shown in the server setup)
uv run mcp run cpp_style_server.py

Additional sections

Configuration, security considerations, and practical usage notes are provided through explicit MCP connection options and clear start commands. You can choose to connect to the remote endpoint or run the local server, depending on your environment and preferences.

Connection options are exposed as explicit MCP configurations. See the examples below for the two available methods.

Security: ensure you control access to the local MCP server and protect any API-like endpoints when exposed in your CI or remote environments.
