Docker Hub MCP server

This is a small helper from Docker that connects your AI assistant to Docker Hub, the online library where container images live. Once it is set up, you can ask your AI in plain words to find images, look up tags, or tidy up your own repositories. It is handy if you work with containers and want to stop clicking around the Docker Hub website.

What this MCP server does

You type a request in your AI chat, like asking for a small Node.js image or a list of your repositories. Your AI passes that request to this helper program. The helper then talks to Docker Hub using your account details, if you gave it any. Docker Hub sends back the answer, and the helper hands it to your AI, which explains it to you in the chat. For some requests it can also make changes, like creating a repository or pushing an image.

What you can do with it

• Search Docker Hub for images by name, size, or category
• Look up the tags and details of a specific image
• List all repositories in your own namespace
• Check whether a repository or a tag already exists
• Create a new repository in your namespace
• Update information on a repository you own
• Find Docker Hardened Images for a more secure setup

Try asking your AI

• “Search for official nginx images on Docker Hub”
• “Show me the latest tag details for go”
• “List all repositories in my namespace”
• “Which of my repositories takes up the most space?”

What it gives back to you

You get answers written in the chat, not files to download. These can be lists of images or repositories, tag names, sizes, dates, and short descriptions. If you asked it to create or update something, it tells you what it changed. Everything shows up as normal text you can read and copy.
