Add cplusplus-mcp to README - C++ code analysis server

[kandrwmrtn]

Description

Adding cplusplus-mcp to the MCP servers list. This server provides semantic C++ code analysis using libclang, enabling Claude to understand C++ codebases through AST parsing rather than text search.

Server Details

• Server: cplusplus-mcp (new addition)
• Changes to: Adding new entry to README.md servers list

Motivation and Context

This server solves the problem of LLMs struggling to understand large C++ codebases through text search alone. By using libclang for semantic analysis, it provides IDE-like code understanding capabilities including class hierarchies, function signatures, and call graph analysis. This is particularly valuable for C++ projects where grep-based searches miss important context like inheritance relationships and function overloading.

How Has This Been Tested?

Tested with Claude Code (npm install -g @anthropic-ai/claude-code) on Windows. Successfully tested scenarios include:

• Searching for classes and functions by pattern
• Analyzing inheritance hierarchies
• Tracing function call graphs
• Understanding template classes and overloaded functions

Breaking Changes

N/A - This is a new server addition

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update
