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

Features

  • 🔍 Web Search Integration: Allows Claude to search for information on the web
  • 🤖 Claude 3 API Support: Works with Claude's latest models and tool use features
  • 🌐 DuckDuckGo Search: Uses DuckDuckGo for ethical, tracking-free search results
  • Fast Responses: Streamlined architecture for quick information retrieval
  • 💬 Natural Conversation: Claude can seamlessly incorporate web search results into conversations

Setup Instructions

Prerequisites

  • Python 3.9 or higher
  • Claude API key

Installation

  1. Clone this repository
  2. Install dependencies:
    pip install -r requirements.txt
  3. Set your Claude API key:
    # On Windows $env:CLAUDE_API_KEY = "your-api-key" # On Linux/Mac export CLAUDE_API_KEY="your-api-key"

Running the Server

  1. Start the MCP server:
    python mcp_server.py
    The server will run on port 5001 by default.
  2. Interact with Claude:
    python ask_claude.py "your question here"
