ITMCP

Secure network administration tools for AI assistants through the Model Context Protocol (MCP).

Overview

ITMCP is an MCP server that enables AI assistants to safely execute networking commands inside a Docker container sandbox. It provides a secure interface for running common network diagnostic and administration tools while maintaining strict security controls.

The project implements the Model Context Protocol (MCP) to expose networking tools as callable functions for AI assistants, allowing them to perform network diagnostics and system administration tasks in a controlled environment.

Features

Docker Isolation: All commands run in a sandboxed Docker container for enhanced security
Security Controls: Comprehensive whitelisting of hosts, directories, and commands
Network Diagnostic Tools: SSH, ping, nslookup, telnet, dig, tcpdump, and more
File Operations: Secure access to view and analyze files with tools like cat, grep, head, tail
Process Management: View running processes with ps and top tools
Credential Management: Secure handling of SSH keys and passwords
MCP Integration: Full compatibility with the Model Context Protocol
Enterprise-Grade Security: Session management, audit logging, and access controls

Installation

Prerequisites

Python 3.10 or higher
Docker (for containerized execution)
MCP library (version 1.0.0 or higher)

Basic Installation

Clone the repository:
git clone https://github.com/yourusername/itmcp.git cd itmcp
Install dependencies:
pip install -e .

Docker Setup

Build the Docker container:
docker build -t itmcp_container .
Run the container:
docker-compose up -d

Configuration

ITMCP uses a YAML-based configuration system and environment variables for setup.

Environment Variables

Create a .env file in the project root with the following variables:

# Docker configuration
USE_DOCKER=true
DOCKER_CONTAINER=itmcp_container

# SSH credentials configuration
SSH_CREDENTIALS_PATH=/app/secrets/ssh_credentials.json
SSH_KEYS_PATH=/app/secrets/keys

# Security whitelists
ALLOWED_HOSTS=localhost,127.0.0.1,example.com
ALLOWED_DIRECTORIES=/tmp,/var/log
ALLOWED_REMOTE_COMMANDS=ls,cat,grep

Security Whitelists

ITMCP implements three key whitelists for security:

Allowed Hosts: Restricts which hosts can be targeted by network tools
Allowed Directories: Limits file system access to specific directories
Allowed Remote Commands: Controls which commands can be executed remotely

Available Tools

ITMCP provides the following network administration tools:

Tool	Description
`ssh_tool`	Connect to a target via SSH
`ping_tool`	Ping a host to check connectivity
`nslookup_tool`	Perform DNS lookup on a hostname or IP address
`telnet_tool`	Test TCP connectivity to a host and port
`dig_tool`	Perform DNS lookup with dig command
`tcpdump_tool`	Capture network packets (limited time)
`ps_tool`	List running processes
`cat_tool`	Display content of a file
`top_tool`	Display system processes (snapshot)
`grep_tool`	Search for patterns in files
`head_tool`	Display the beginning of a file
`tail_tool`	Display the end of a file

Security Features

ITMCP implements enterprise-grade security features:

Session Management

Secure session creation with cryptographic tokens
Session expiration and timeout controls
Concurrent session limits
Session validation and regeneration

Audit Logging

Comprehensive command logging
User attribution for all actions
Success/failure logging
Security event flagging
Tamper-evident logs

Access Control

Command whitelisting
Directory restrictions
Host restrictions
Input validation and sanitization

Docker Integration

ITMCP uses Docker to create a secure sandbox for command execution:

All commands are routed through the Docker container
The container has limited access to the host system
Resource limits can be applied to prevent abuse
Network isolation provides an additional security layer

Security Considerations

ITMCP is designed with security in mind, but proper configuration is essential:

Always run in a Docker container for isolation
Carefully configure whitelists for hosts, directories, and commands
Regularly review audit logs for suspicious activity
Keep the system updated with security patches
Follow the security best practices in the documentation

This server cannot be installed

security - not tested

license - not tested

quality - not tested

remote-capable server

The server can be hosted and run remotely because it primarily relies on remote services or has no dependency on the local environment.

Secure network administration MCP server that enables AI assistants to safely execute networking commands like SSH, ping, and DNS lookups inside a Docker container sandbox.
