Claude MCP Server

A lightweight bridge enabling Claude AI to search the web in real-time. This Flask-based server integrates Claude's advanced capabilities with DuckDuckGo search, allowing the AI to access current information during conversations.

Project Overview

This project implements a server that enables Claude to perform web searches during conversations. It consists of:

1. MCP Server: A Flask server that handles tool calls and performs web searches

2. Claude Integration: A client that connects to Claude's API and manages tool use capabilities

3. Command-line Interface: A simple way to interact with Claude + web search capabilities
