Claude Custom Tools Server

This project implements a Model Context Protocol (MCP) server in Python that connects to Claude Desktop and exposes multiple custom tools such as:

• 🏠 Airbnb (simulated search)
• 🔍 DuckDuckGo web search
• 📚 Wikipedia search
• 📄 ArXiv research papers
• ➕➗ Custom math tools (add, multiply)

Claude can automatically invoke these tools via MCP using stdio communication.
