Model Context Protocol (MCP) Implementation

🌟 Features

• 🚀 Implementation of the Model Context Protocol (MCP)
• 🤖 Integration with Anthropic's Claude AI model
• 🛠️ Tool execution system with JSON-RPC communication
• 🔐 Environment variable configuration for API keys
• ⏰ Example tool implementation (get_current_time)

📋 Prerequisites

• Python 3.11 or higher
• Anthropic API key
• pip (Python package installer)

🚀 Installation

1. Clone the repository:

git clone <your-repository-url>
cd <repository-name>

2. Install the required dependencies:

pip install -r requirements.txt

3. Create a .env file in the root directory and add your Anthropic API key:

ANTHROPIC_API_KEY=your_api_key_here

📁 Project Structure

.
├── chatbot.py          # Main client implementation
├── mcp_server.py      # Server implementation
├── requirements.txt   # Python dependencies
└── .env              # API key configuration (not in repo)

💻 Usage

1. Start the chatbot:

python chatbot.py

2. Interact with the chatbot in the terminal:
   • Ask questions that might require tool usage
   • Type "exit" to quit the program

📝 Example Interaction

User: What time is it?
Assistant: Let me check the current time for you.
Found 1 tool calls
Tool get_current_time result: 2024-03-26 15:30:45
Assistant: The current time is 2024-03-26 15:30:45.

🔧 How It Works

1. The MCPClient class manages communication with the MCP server using JSON-RPC
2. When a user sends a message, it's processed by Claude
3. If Claude determines a tool is needed, it makes a tool call
4. The tool call is executed by the MCP server
5. The result is sent back to Claude for final response generation

🔒 Security

• 🔑 API keys are stored in .env file and not committed to the repository
• 🚫 The .env file is included in .gitignore to prevent accidental commits
