Container Registry MCP Servers — Docker Hub, ECR, ACR, JFrog, Harbor, and Beyond

At a glance: Official vendor investment is strong but narrowly scoped. Docker Hub has an official 13-tool MCP server. JFrog has the most comprehensive offering at 22+ tools. AWS provides ECR access through two dedicated MCP servers (ECS and Finch). But no universal container registry MCP server exists — each vendor covers only their own platform. 12+ servers across 8 platforms. Rating: 3.5/5.
