Installation

Via npm (Recommended)

npm install -g @swartdraak/docker-mcp-server

From Source

Prerequisites

• Node.js 18 or higher
• Docker installed and running
• npm or yarn package manager

Setup

1. Clone the repository:

git clone https://github.com/Swartdraak/Docker-MCP.git
cd Docker-MCP

1. Install dependencies:

npm install

1. Build the project:

npm run build

Usage

Standalone Mode

Run the server directly:

npm start

Remote Docker Configuration

The MCP server supports connecting to remote Docker hosts using environment variables:

Connect to Remote Docker via TCP

DOCKER_HOST=tcp://192.168.1.100:2375 npm start

Connect to Remote Docker via HTTPS with TLS

DOCKER_HOST=https://192.168.1.100:2376 \
DOCKER_TLS_VERIFY=1 \
DOCKER_CERT_PATH=~/.docker/certs \
npm start

Connect via SSH Tunnel

First, set up an SSH tunnel:

ssh -NL localhost:2375:/var/run/docker.sock user@remote-host

Then connect to the tunneled Docker:

DOCKER_HOST=tcp://localhost:2375 npm start

VS Code Integration

To integrate with VS Code and GitHub Copilot, add the following to your MCP settings file:

For Local Docker (~/.vscode/mcp-settings.json or in your workspace settings):

{
  "mcpServers": {
    "docker": {
      "command": "node",
      "args": ["/path/to/Docker-MCP/dist/index.js"]
    }
  }
}

For Remote Docker over TCP:

{
  "mcpServers": {
    "docker": {
      "command": "node",
      "args": ["/path/to/Docker-MCP/dist/index.js"],
      "env": {
        "DOCKER_HOST": "tcp://192.168.1.100:2375"
      }
    }
  }
}

For Remote Docker with TLS:

{
  "mcpServers": {
    "docker": {
      "command": "node",
      "args": ["/path/to/Docker-MCP/dist/index.js"],
      "env": {
        "DOCKER_HOST": "https://192.168.1.100:2376",
        "DOCKER_TLS_VERIFY": "1",
        "DOCKER_CERT_PATH": "/home/user/.docker/certs"
      }
    }
  }
}

For Claude Desktop (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "docker": {
      "command": "node",
      "args": ["/path/to/Docker-MCP/dist/index.js"]
    }
  }
}

Alternative using npx (after publishing to npm):

{
  "mcpServers": {
    "docker": {
      "command": "npx",
      "args": ["@swartdraak/docker-mcp-server"]
    }
  }
}

Testing Your Connection

Connection Test Utility

Before using the MCP server, you can test your Docker connection with the included test utility:

# Test local Docker connection
node test-connection.js

# Test remote Docker via TCP
DOCKER_HOST=tcp://192.168.1.100:2375 node test-connection.js

# Test remote Docker via TLS
DOCKER_HOST=https://192.168.1.100:2376 \
DOCKER_TLS_VERIFY=1 \
DOCKER_CERT_PATH=~/.docker/certs \
node test-connection.js

# Test SSH tunnel connection
DOCKER_HOST=tcp://localhost:2375 node test-connection.js

The test utility will:

• ✓ Validate your configuration
• ✓ Check TLS certificates (if applicable)
• ✓ Test connection to Docker daemon
• ✓ Verify Docker operations (list containers, images, networks, volumes)
• ✓ Display system information
• ✓ Provide troubleshooting recommendations

validate_connection Tool

Once the MCP server is running, you can also use the validate_connection tool from your AI assistant:

"Validate my Docker connection"

This tool performs runtime connectivity tests and returns:

• Connection status
• Docker version and API information
• System information
• Test results for common operations

Manual Testing

You can also test your connection directly with Docker CLI:

# Set environment variables
export DOCKER_HOST=tcp://192.168.1.100:2375

# Test commands
docker version
docker info
docker ps

• CONFIGURATION.md - MCP server configuration examples
• REMOTE_SETUP.md - Comprehensive remote connection setup guide (includes Windows 11 specific instructions)
