Installation

Quick Start with npm

# Install and run
npx cpp-enhancement-mcp-server

# First-time setup (configure Brave Search API)
npx cpp-enhancement-mcp-server --setup

# Run interactive demo
npx cpp-enhancement-mcp-server --demo

Manual Installation

1. Install dependencies:

pip install -r requirements.txt

2. Setup Brave Search API (optional but recommended):

python cpp_enhancement_server.py --setup

See BRAVE_SEARCH_SETUP.md for detailed instructions.

3. Configure MCP client: Add the server configuration to your MCP client (Claude Desktop, Cursor, etc.):

{
  "mcpServers": {
    "cpp-enhancement": {
      "command": "npx",
      "args": ["cpp-enhancement-mcp-server"],
      "env": {},
      "description": "C++ Programming Enhancement MCP Server"
    }
  }
}

4. Run the server:

python cpp_enhancement_server.py

Available Tools

Parameters:

• topic (string): C++ topic (auto, smart_pointers, move_semantics, etc.)
• include_examples (boolean, optional): Include code examples

suggest_modern_alternatives

Suggest modern C++ alternatives to legacy code patterns.

Parameters:

• legacy_code (string): Legacy C++ code to modernize
• target_standard (string, optional): Target C++ standard (cpp11, cpp14, cpp17, cpp20, cpp23)

performance_optimization_tips

Get performance optimization suggestions.

Parameters:

• code (string): C++ code to optimize
• optimization_type (string, optional): Type of optimization (cache_locality, vectorization, memory_management, general)

memory_management_advice

Get advice on memory management and RAII.

Parameters:

• code (string): C++ code with memory management concerns
• focus (string, optional): Focus area (smart_pointers, raii, memory_leaks, ownership)

template_programming_help

Get help with template metaprogramming.

Parameters:

• code (string): Template code or description
• technique (string, optional): Specific technique (sfinae, crtp, concepts, variadic_templates, type_traits)

Usage Examples

Code Analysis

# Analyze code for improvements
result = await analyze_cpp_code(
    code="int* ptr = new int(42); delete ptr;",
    focus_areas=["memory_safety", "modern_features"]
)

Get Best Practices

# Get smart pointer best practices
result = await get_cpp_best_practices(
    topic="smart_pointers",
    include_examples=True
