Repair Windows errors before they cause bigger problemsFix Now →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →The most direct way to run a published MCP server from Docker Hub is to let your MCP client start its image as a local stdio process. For Docker’s Hub MCP server, authenticate to the dhi.io registry, add a client entry that runs docker run --rm -i dhi.io/hub-mcp, restart the client, and verify a tool call. This example manages Docker Hub image and repository information; substitute the image and arguments documented by another MCP server.
Choose the Docker route that matches your goal
“Run an MCP server from Docker Hub” can describe two different Docker workflows. They are not interchangeable:
| Route | Best for | How the server starts |
|---|---|---|
| Direct image invocation | You already know the registry image and want your client to launch it locally | The client executes docker run over stdio |
| Docker MCP Toolkit | You want a catalog, profiles and a managed gateway | Docker Desktop manages the server and client connection |
| Source build | You need to inspect or modify the server | You build and start the repository with Node.js |
The rest of this procedure uses Docker’s published dhi.io/hub-mcp image. It searches and manages Docker Hub information, rather than providing arbitrary tools for every Docker image.
Prerequisites
- Docker Engine or Docker Desktop installed and usable by your account.
- An MCP-compatible client that accepts a local stdio server, such as Claude Desktop, Claude Code, Codex or another client with equivalent configuration.
- Access to the
dhi.ioregistry. Docker’s Hardened Images example instructs you to rundocker login dhi.iobefore pulling the image. - A text editor and permission to restart or refresh the client after changing its MCP configuration.
Use a client’s own configuration location and JSON schema. Docker’s examples differ between clients; do not copy a Claude Desktop configuration into a client that expects a different shape.

Run the Docker Hub MCP server directly
1. Log in to the registry
In a terminal, authenticate to the registry named by the image:
docker login dhi.ioComplete the credential prompt using the account accepted by your registry. A successful login stores credentials for subsequent pulls. Do not place registry passwords or personal access tokens in a shared configuration file.
2. Add the server to your MCP client
For Claude Desktop, Docker’s public-repository example is:
{
"mcpServers": {
"docker-hub": {
"command": "docker",
"args": ["run", "--rm", "-i", "dhi.io/hub-mcp"]
}
}
}The fields have practical consequences:
commandtells the client to execute Docker on the host.runcreates and starts a container from the image.--rmremoves the stopped container when the client disconnects.-ikeeps standard input open, which is required for the MCP stdio stream.dhi.io/hub-mcpidentifies the published server image.
Save the entry in the client’s documented MCP configuration file. If that file already contains other servers, add the docker-hub object without deleting them, and preserve valid commas and braces.
Recommended Free Tools
3. Restart and verify
- Completely restart the MCP client, or use its reload command if it documents one.
- Check that the server is shown as connected or enabled.
- Send a low-risk request that uses a Docker Hub tool, for example: Search for official nginx images on Docker Hub.
- Try a repository-specific request, such as: Show me all tags for my “repository-name” repository.
The first request checks public discovery. Private repositories require the authenticated configuration described next.

Use private repositories and authenticated requests
Docker’s Hardened Images example passes a personal access token through HUB_PAT_TOKEN and supplies the Docker Hub username as an argument:
{
"mcpServers": {
"docker-hub": {
"command": "docker",
"args": [
"run", "--rm", "-i",
"-e", "HUB_PAT_TOKEN=your-access-token",
"dhi.io/hub-mcp",
"--username", "<your username>"
]
}
}
}Replace both values with your own credentials. The token is optional for public content, but private repository access and repository management need authentication. Prefer your client’s supported secret or environment mechanism over committing a live token to a configuration file. If the client cannot protect inline environment values, inject HUB_PAT_TOKEN through a host-level secret facility and adapt the command to that client’s documented syntax.
Use Docker MCP Toolkit instead
Docker Desktop’s MCP Toolkit is a catalog-and-gateway workflow, not a shorter spelling of the direct docker run command. The current interface instructions target Docker Desktop 4.62 and later; earlier releases have different UI.
The Tool Desk
Outbyte PC Repair FREERepair Windows errors before they cause bigger problemsFix Now →Outbyte Driver Updater FREEFix the driver behind crashes, sound loss and screen glitchesFind Drivers →- Open Docker Desktop and enable MCP Toolkit.
- Create or select a profile.
- Add the desired server from the catalog.
- Complete any required fields, including credentials where requested.
- Connect your AI client from the Toolkit interface.
- Confirm the client lists the gateway or server as connected, then invoke one of its tools.
For a compatible client configured manually, Docker documents this stdio gateway command:
docker mcp gateway run --profile my_profileChoose Toolkit when several servers must be managed under profiles or when you want Docker Desktop to handle catalog selection and client connections. Choose direct invocation when you have a known image and need a transparent local subprocess.

Build the Docker Hub server from source
The hub-mcp source repository is the alternative when you need to inspect or change the implementation. Its documented prerequisites are Docker and Node.js 22 or later.
npm install
npm run build
npm startThe source server supports stdio (the default) and HTTP transport. Its documented HTTP default is port 3000. Public Docker Hub content works without a token; authenticated repository operations require a PAT and username. Configure the resulting process using the client’s source-process format. Docker’s Hub MCP documentation shows a Node.js process configuration for Claude Desktop and VS Code, while the Hardened Images guide shows the Docker-process configuration above; do not mix those snippets.

Confirm the image and platform
Image names and tags can change. Before standardizing a deployment, inspect the image manifest and verify that your host architecture is supported. Docker’s image-building guidance recommends publishing multi-platform images and names amd64 and arm64 as common targets. That recommendation does not prove that every tag of dhi.io/hub-mcp supports both platforms, so check the current manifest for the exact image you use.
Understand the process boundary
With direct invocation, the MCP client owns a Docker child process, and Docker owns the container. The server communicates through stdin/stdout; diagnostic output should not be mixed into the protocol stream. The container is ephemeral because of --rm. Persistent state, if a different server needs it, must be provided through that server’s documented volumes or external services.
Plan for upgrades
Pin a tested image tag or digest for repeatable environments when the publisher provides one, and update it deliberately. If you use the Toolkit catalog, record the profile and server version selected there. Recheck client compatibility after changing Docker Desktop, the image or the MCP client.

Troubleshooting
The image cannot be pulled
Cause: the registry login is missing, expired or pointed at the wrong registry. Fix: run docker login dhi.io, verify the exact image name, and retry. A network proxy or organization policy can also block registry access; test Docker’s registry connectivity outside the MCP client.
The client says the server is disconnected
Cause: invalid JSON, an incorrect configuration path, a client that does not support local stdio, or a Docker executable unavailable on the client’s PATH. Fix: validate the JSON, use the client’s documented MCP settings, run docker --version as the same user, and restart the client completely.
The server starts and immediately exits
Cause: the image is incompatible with the host architecture, required arguments are missing, or Docker cannot create the container. Fix: run the same docker run command manually to expose the error, inspect the image manifest, and compare required options with the image documentation.
Public searches work but private repositories fail
Cause: no PAT was supplied, the PAT lacks the required scope, or the username argument is wrong. Fix: provide HUB_PAT_TOKEN and --username through a protected secret mechanism, then restart the client. Never paste the token into a prompt or commit it to source control.
Toolkit instructions do not match your screen
Cause: Docker Desktop is older than 4.62 or the feature is unavailable in your edition. Fix: check the installed version and use the documentation for that release, or use the direct image route, which does not require Toolkit UI.

Tools appear connected but return no useful result
Cause: the request does not match a tool exposed by this server, or the server is being asked to manage data outside Docker Hub. Fix: begin with a public image search, inspect the tools listed by the client, and use a different MCP server image for a different service.

Frequently Asked Questions
Can I run any Docker Hub image as an MCP server?
No. The image must implement the MCP protocol and expose the transport expected by your client. A normal web or command-line container is not automatically an MCP server.
Does the direct command require Docker Desktop?
No. It requires a working Docker Engine or Docker Desktop installation. The client only needs to be able to execute the Docker CLI.
When should I use HTTP instead of stdio?
Use the transport explicitly supported by the server and client. The documented hub-mcp source build defaults to stdio and also supports HTTP on port 3000; direct client-launched containers normally use stdio.
