mcp-docker-tools

Docker management tools for AI agents, built on the Model Context Protocol.

Provides five tools for inspecting containers, images, Dockerfiles, and Compose configurations — all accessible to LLMs through MCP.

Tools

| Tool | Description | |------|-------------| | docker_container_list | List running or all containers with status, ports, image, created time, and resource usage (CPU, memory, network/block I/O) | | docker_image_list | List Docker images with size, tags, created date, and layer count | | docker_dockerfile_analyze | Analyze a Dockerfile for best practices: multi-stage builds, non-root user, layer caching, image size, security | | docker_compose_analyze | Analyze docker-compose.yml: services, ports, volumes, networks, health checks, dependencies, and improvement suggestions | | docker_container_logs | Get container logs with tail, keyword filter, time range, and timestamp support |

Prerequisites

• Node.js >= 18
• Docker CLI installed and accessible in PATH
• Docker daemon running (for container/image tools)

Installation

git clone <repo-url>
cd mcp-docker-tools
npm install
npm run build

      "command": "node",
      "args": ["D:/products/mcp-servers/mcp-docker-tools/dist/index.js"]
    }
  }
}

Usage with Claude Code

claude mcp add docker-tools node D:/products/mcp-servers/mcp-docker-tools/dist/index.js

Or add to .claude/settings.json:

{
  "mcpServers": {
    "docker-tools": {
      "command": "node",
      "args": ["D:/products/mcp-servers/mcp-docker-tools/dist/index.js"]
    }
  }
}
