📦 Claude MCP Custom Tools Server (Python)

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.
