MCP Server Docker - NPX Wrapper

Usage: npx mcp-server-docker [options]

Options:
  --docker-host <host>    Docker host URL (default: unix:///var/run/docker.sock)
  --help, -h             Show this help message

Environment Variables:
  DOCKER_HOST            Docker host URL
  MCP_SERVER_DOCKER_HOST Override Docker host for MCP server

Examples:
  npx mcp-server-docker
  npx mcp-server-docker --docker-host tcp://192.168.1.100:2376
  DOCKER_HOST=ssh://user@host npx mcp-server-docker
