Introduction

The Model Context Protocol (MCP) has revolutionized how AI agents interact with external systems and data sources. However, setting up individual MCP servers can be complex and time-consuming. MCP Containers by Metorial solves this challenge by providing containerized versions of hundreds of MCP servers, making it incredibly simple to integrate powerful AI capabilities into your applications.

In this comprehensive tutorial, we’ll explore how to use MCP Containers to build sophisticated AI agents that can interact with databases, APIs, file systems, and much more - all through Docker containers.

What is MCP and Why MCP Containers?

Understanding Model Context Protocol

The Model Context Protocol (MCP) is an open standard that enables AI models to securely connect to external data sources and tools. It provides a standardized way for AI agents to:

  • Access databases and APIs
  • Interact with file systems
  • Execute commands securely
  • Process various data formats
  • Integrate with third-party services

The Challenge with Traditional MCP Setup

Setting up MCP servers traditionally involves:

  • Complex dependency management
  • Environment configuration
  • Security considerations
  • Version compatibility issues
  • Time-consuming setup processes

MCP Containers Solution

MCP Containers addresses these challenges by providing:

  • 🚀 Simple Setup: Just pull the Docker image
  • 🛠️ Always Up-to-Date: Automatically updated daily
  • 🔒 Secure: Isolated container execution
  • 📦 Comprehensive: Hundreds of pre-built servers

Prerequisites

Before we begin, ensure you have:

  • Docker installed and running
  • Basic understanding of Docker commands
  • Familiarity with AI/LLM concepts
  • Text editor or IDE
  • Terminal/command line access

Getting Started with MCP Containers

Step 1: Basic Container Usage

The fundamental pattern for using MCP Containers is straightforward:

# Basic syntax
docker run -it ghcr.io/metorial/mcp-containers:{server-name}

# Example: Running a filesystem server
docker run -it -v $(pwd):/workspace ghcr.io/metorial/mcp-containers:filesystem

Step 2: Understanding Container Architecture

Each MCP Container follows a consistent structure:

Container Structure:
├── MCP Server Implementation
├── Required Dependencies
├── Security Configuration
├── Standard Input/Output Interface
└── Error Handling

Practical Examples

Example 1: File System Integration

Let’s start with a practical example using the filesystem MCP server:

# Create a working directory
mkdir mcp-demo
cd mcp-demo

# Create sample files
echo "Hello MCP World!" > sample.txt
echo "This is a test file." > test.txt

# Run filesystem MCP server
docker run -it -v $(pwd):/workspace ghcr.io/metorial/mcp-containers:filesystem

Use Cases:

  • File content analysis
  • Automated document processing
  • Code review and analysis
  • Data extraction from documents

Example 2: Database Integration

For database operations, let’s use the SQLite MCP server:

# Create a sample SQLite database
sqlite3 demo.db "CREATE TABLE users (id INTEGER PRIMARY KEY, name TEXT, email TEXT);"
sqlite3 demo.db "INSERT INTO users (name, email) VALUES ('John Doe', 'john@example.com');"

# Run SQLite MCP server
docker run -it -v $(pwd):/workspace ghcr.io/metorial/mcp-containers:sqlite

Capabilities:

  • Query execution
  • Data analysis
  • Report generation
  • Database schema exploration

For web search capabilities:

# Set up environment variable for API key
export BRAVE_API_KEY="your_brave_api_key_here"

# Run Brave search MCP server
docker run -it -e BRAVE_API_KEY=${BRAVE_API_KEY} ghcr.io/metorial/mcp-containers:brave-search

Features:

  • Real-time web search
  • Information gathering
  • Research automation
  • Content discovery

Advanced Configuration

Environment Variables and Secrets

Many MCP servers require configuration through environment variables:

# Example with multiple environment variables
docker run -it \
  -e API_KEY="your_api_key" \
  -e BASE_URL="https://api.example.com" \
  -e TIMEOUT="30" \
  ghcr.io/metorial/mcp-containers:your-server

Volume Mounting Strategies

Different mounting strategies for various use cases:

# Read-only access
docker run -it -v $(pwd):/workspace:ro ghcr.io/metorial/mcp-containers:filesystem

# Specific directory mounting
docker run -it -v /path/to/data:/data ghcr.io/metorial/mcp-containers:server

# Multiple volume mounts
docker run -it \
  -v $(pwd)/input:/input:ro \
  -v $(pwd)/output:/output \
  ghcr.io/metorial/mcp-containers:processor

Network Configuration

For servers requiring network access:

# Custom network
docker network create mcp-network
docker run -it --network mcp-network ghcr.io/metorial/mcp-containers:server

    networks:
      - mcp-network

volumes:
  database:

networks:
  mcp-network:
    driver: bridge

Event-Driven Architecture

Implement event-driven workflows:

#!/bin/bash
# event-driven-mcp.sh

# Watch for file changes and trigger processing
inotifywait -m /watch/directory -e create -e modify |
while read path action file; do
    echo "File $file was $action"
    
    # Trigger MCP processing
    docker run --rm \
