The Docker Hub MCP Server is a Model Context Protocol (MCP) server that interfaces with Docker Hub APIs to make them accessible to LLMs, enabling intelligent content discovery and repository management.
Developers building with containers, especially in AI and LLM-powered workflows, often face inadequate context across the vast landscape of Docker Hub images. As a result, LLMs struggle to recommend the right images, and developers lose time manually searching instead of building.

Use Cases
AI-powered image recommendations - LLMs access real-time Docker Hub data for accurate container image suggestions.
Enhanced content discovery - AI tools help developers find the right images faster.
Simplified Hub workflows - Manage Docker repositories and images using natural language.
transport: Choose between http or stdio (default: stdio)
port=3000
host=127.0.0.1 (HTTP transport only)
This starts the server with default settings and can only access public Docker Hub content.
[!IMPORTANT]
The http transport binds to 127.0.0.1 (loopback) by default and requires
authentication. See Securing the HTTP transport
before exposing it to a network.
Run in inspector [Optional]
The MCP Inspector provides a web interface to test your server:
The stdio transport is only reachable by the local process that spawns it. The
http transport, however, dispatches every tool call using the server operator's
Docker Hub Personal Access Token (HUB_PAT_TOKEN). Anyone who can reach the HTTP
endpoint can therefore act as that Docker Hub identity — including creating and
modifying repositories. To prevent this, the HTTP transport is locked down by
default:
Loopback binding. The listener binds to 127.0.0.1 unless you pass
--host=<addr> (for example --host=0.0.0.0 to expose it from a container).
Authentication required (fail-closed). In http mode the server refuses to
start unless you either provide a bearer token or explicitly opt out. Set the
token via the MCP_AUTH_TOKEN environment variable; clients must then send it as
Authorization: Bearer <token> on every request.
DNS-rebinding / CSRF protection. Requests are rejected when the Host header
is not in the allow-list (loopback plus --host, extendable with
--allowed-hosts), or when they carry a browser Origin header that is not
listed in --allowed-origins. Non-browser MCP clients are unaffected.
Extra Host header values to accept (comma-separated).
--allowed-origins=a,b
Browser Origin values to accept (comma-separated).
--allow-unauthenticated
Serve /mcp with no authentication. Insecure; opt-in only.
[!WARNING]
--allow-unauthenticated disables authentication entirely and exposes your
Docker Hub PAT to any client that can reach the port. Only use it on a trusted,
isolated network.
Authenticate with docker
By default this MCP server can only query public content on Docker Hub. In order to manage your repositories you need to provide authentication.
You can configure Gordon to be a host that can interact with the Docker Hub MCP server.
Gordon Setup
Ask Gordon is your personal AI assistant embedded in Docker Desktop and the Docker CLI. It's designed to streamline your workflow and help you make the most of the Docker ecosystem.
You can configure Gordon to be a client that can interact with the Docker Hub MCP server.
NOTE: Make sure you have already built the application as mentioned in Step 1.
Add the Docker Hub MCP Server configuration to your claude_desktop_config.json:
NOTE: if you are using nvm to manage node versions, you should put the node binary path in the command property. This ensure MCP server runs with the right node version. You can find your binary path by running which node in your shell
For public repositories only:
/FULL/PATH/TO/YOUR/docker-hub-mcp-server - The complete path to where you cloned this repository
Save the configuration file and completely restart Claude Desktop for the changes to take effect.
Usage with VS Code
Add the Docker Hub MCP Server configuration to your User Settings (JSON) file in VS Code. You can do this by opening the Command Palette and typing Preferences: Open User Settings (JSON).
For public repositories only:
/FULL/PATH/TO/YOUR/docker-hub-mcp-server - The complete path to where you cloned this repository
Open the Command Palette and type MCP: List Servers.
Select docker-hub and select Start Server.
