MCP-Client-Server-with-LLM-Command-Execution

Machine Command Processor (MCP)

A client-server system that uses LLMs to convert natural language queries into shell commands. The system consists of three main components: a client that processes natural language queries through Groq's LLM API, a server that executes shell commands, and a shared protocol for communication.

Features

• Natural language to shell command conversion using Groq's LLM API
• WebSocket-based client-server communication
• Command execution safety checks
• Comprehensive logging system
• Asynchronous operation using Python's asyncio
• Structured message protocol with UUID tracking

Prerequisites

• Python 3.7+
• Groq API key
• WebSocket support
• Required Python packages:
  • websockets
  • groq
  • asyncio
  • logging

Installation

1. Clone the repository
2. Install required packages:

pip install websockets groq

3. Set up your Groq API key:

export GROQ_API_KEY='your-api-key'

Components

MCP Client (mcp_client.py)

• Handles user input
• Connects to Groq API for command generation
• Communicates with server via WebSocket
• Processes and displays results

MCP Server (mcp_server.py)

• Executes shell commands
• Implements command safety checks
• Manages WebSocket connections
• Returns command execution results

Protocol (mcp_protocol.py)

• Defines message structure
• Handles message serialization/deserialization
• Provides message creation utilities

Usage

1. Start the server:

python mcp_server.py

2. In a separate terminal, start the client:

python mcp_client.py

3. Enter natural language queries when prompted. For example:

Enter your query: list all files in the current directory

Security Features

• Blocked dangerous commands including:
  • sudo
  • rm -rf
  • mkfs
  • dd
  • format
• Command validation before execution
• Logged operations for audit trails

Logging

The system maintains two log files:

• mcp_client.log: Client-side operations and LLM interactions
• mcp_server.log: Server-side operations and command execution
