Implementation Reference

• cpp_style_server.py:106-125 (handler)

  The primary MCP tool handler for 'suggest_modern_cpp'. It defines the tool schema via type hints and docstring, registers it with @mcp.tool(), and delegates execution to the ModernCppSuggester class.

  @mcp.tool()
  def suggest_modern_cpp(code: str, target_standard: str = "cpp17") -> str:

• cpp_style/tools/modern_cpp.py:10-42 (helper)

  Core implementation of modernization suggestions in ModernCppSuggester class. Orchestrates feature checks via regex patterns for different C++ standards and generates a formatted report.

• cpp_style/tools/modern_cpp.py:343-349 (helper)

  Singleton factory function providing the shared ModernCppSuggester instance used by the tool handler.

• cpp_style_server.py:106-106 (registration)

  MCP tool registration decorator for 'suggest_modern_cpp'.
