Docker Hub MCP server

The Docker Hub MCP Server is a Model Context Protocol (MCP) server that interfaces with Docker Hub APIs to make rich image metadata 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.

Key features

• Advanced LLM context: Our MCP Server provides LLMs with detailed, structured context for Docker Hub images, enabling smarter, more relevant recommendations for developers, whether they're choosing a base image or automating CI/CD workflows.
• Natural language image discovery: Developers can find the right container image using natural language, no need to remember tags or repository names. Just describe what you need, and Docker Hub will return images that match your intent.
• Simplified repository management: Hub MCP Server enables agents to manage repositories through natural language fetching image details, viewing stats, searching content, and performing key operations quickly and easily.

Install Docker Hub MCP server

1. From the MCP Toolkit menu, select the Catalog tab and search for Docker Hub and select the plus icon to add the Docker Hub MCP server.

2. In the server's Configuration tab, insert your Docker Hub username and personal access token (PAT).

3. In the Clients tab in MCP Toolkit, ensure Gordon is connected.

4. From the Ask Gordon menu, you can now send requests related to your Docker Hub account, in accordance to the tools provided by the Docker Hub MCP server. To test it, ask Gordon:

   What repositories are in my namespace?

Tip

By default, the Gordon client is enabled, which means Gordon can automatically interact with your MCP servers.

Using other clients

If want to integrate the Docker Hub MCP Server into your own development environment, you can find the source code and installation instructions on our GitHub repository.

Use Claude Desktop as a client

1. Add the Docker Hub MCP Server configuration to your claude_desktop_config.json:

For public repositories only

• /FULL/PATH/TO/YOUR/docker-hub-mcp-server - The complete path to where you cloned this repository

{
  "mcpServers": {
    "docker-hub": {
      "command": "node",
      "args": ["/FULL/PATH/TO/YOUR/docker-hub-mcp-server/dist/index.js", "--transport=stdio"]
    }
  }
}

For authenticated access

Replace the following values:

• YOUR_DOCKER_HUB_USERNAME - Your Docker Hub username
• YOUR_DOCKER_HUB_PERSONAL_ACCESS_TOKEN - Your Docker Hub Personal Access Token
• /FULL/PATH/TO/YOUR/docker-hub-mcp-server - The complete path to where you cloned this

{
  "mcpServers": {
    "docker-hub": {
      "command": "node",
      "args": ["/FULL/PATH/TO/YOUR/docker-hub-mcp-server/dist/index.js", "--transport=stdio", "--username=YOUR_DOCKER_HUB_USERNAME"],
      "env": {
        "HUB_PAT_TOKEN": "YOUR_DOCKER_HUB_PERSONAL_ACCESS_TOKEN"
      }
    }
  }
}

1. Save the configuration file and completely restart Claude Desktop for the changes to take effect.

Usage with VS Code

1. 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

{
  "mcpServers": {
    "docker-hub": {
      "command": "node",
      "args": ["/FULL/PATH/TO/YOUR/docker-hub-mcp-server/dist/index.js", "--transport=stdio"]
    }
  }
}

For authenticated access

Replace the following values:

• YOUR_DOCKER_HUB_USERNAME - Your Docker Hub username
• YOUR_DOCKER_HUB_PERSONAL_ACCESS_TOKEN - Your Docker Hub Personal Access Token
• /FULL/PATH/TO/YOUR/docker-hub-mcp-server - The complete path to where you cloned this

{
  "mcpServers": {
    "docker-hub": {
      "command": "node",
      "args": ["/FULL/PATH/TO/YOUR/docker-hub-mcp-server/dist/index.js", "--transport=stdio"],
      "env": {
        "HUB_USERNAME": "YOUR_DOCKER_HUB_USERNAME",
        "HUB_PAT_TOKEN": "YOUR_DOCKER_HUB_PERSONAL_ACCESS_TOKEN"
      }
    }
  }
}

1. Open the Command Palette and type MCP: List Servers.
2. Select docker-hub and select Start Server.
