   DEPLOYMENT_NAME=your_deployment_name
   

Usage

1. Start the MCP server:

   python mcp_server.py
   

2. In a new terminal, start the Flask application:

   python app.py
   

3. Access the chatbot interface at http://localhost:5000

MCP Protocol

The Model Context Protocol (MCP) is implemented to handle message communication between the chatbot and the server. It provides:

• Secure message transmission
• Message queuing and reliability
• Detailed logging
• Real-time message handling

Message Types

• Chat Messages: User queries and AI responses
• System Messages: Administrative and control messages

Logging

The application maintains detailed logs in the logs directory:

• client_messages.log: Chat message history
• mcp_client.log: Client connection and operation logs
• mcp_server.log: Server operation logs

Bank Information

The chatbot is configured with comprehensive bank information including:

• Business hours
• Branch locations
• Available services
• Contact information
• Support channels

Development

Adding New Features

1. Update the BANK_INFO dictionary in app.py for new bank information
2. Modify the SYSTEM_MESSAGE for updated AI behavior
3. Add new message handlers in mcp_client.py for additional functionality

Testing

Run the test client to verify MCP functionality:

python test_client.py

Clear logs for testing:

python clear_logs.py

Security

• API keys and sensitive information are stored in .env
• MCP provides secure message transmission
• Input validation and error handling are implemented
