ArtifactHub MCP server

This MCP server enables interaction with Helm charts on ArtifactHub directly from your development environment. It provides tools for retrieving chart information, values files, and templates through the Model Context Protocol.

Installation

Using Visual Studio Code

The easiest way to install is using the VS Code auto-install link. Just click this auto-install-link in your browser.

Manual Configuration

Alternatively, you can manually configure the MCP server in your MCP client configuration:

{
	"servers": {
		"artifacthub-mcp": {
			"type": "stdio",
			"command": "docker",
			"args": ["run", "-i", "--rm", "ghcr.io/alexw00/artifacthub-mcp"]
		}
	}
}

This configuration uses Docker to run the server, so ensure Docker is installed on your system.

Available Tools

The ArtifactHub MCP server provides several tools for working with Helm charts:

helm-chart-info

Retrieve basic information about a Helm chart including its ID and latest version.

helm-chart-values

Get the default values.yaml file for a specific Helm chart.

helm-chart-values-fuzzy-search

Search within a chart's default values file using fuzzy matching to quickly find configuration options.

helm-chart-template

Retrieve a specific template from a Helm chart by providing the template name.

helm-chart-template-fuzzy-search

Perform fuzzy searching across template names and contents to find relevant templates.

Usage Examples

Each tool can be invoked through your MCP client. Here are some examples of how you might use them:

Getting Chart Information

Use helm-chart-info to retrieve basic information about a chart:

helm-chart-info bitnami/postgresql

Retrieving Values File

Get the default values file for a chart:

helm-chart-values bitnami/nginx

Searching Values

Find specific configuration options using fuzzy search:

helm-chart-values-fuzzy-search bitnami/mysql root password

Working with Templates

Get a specific template:

helm-chart-template bitnami/wordpress templates/deployment.yaml

Or search across templates:

helm-chart-template-fuzzy-search bitnami/redis configmap

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "artifacthub-mcp" '{"type":"stdio","command":"docker","args":["run","-i","--rm","ghcr.io/alexw00/artifacthub-mcp"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "artifacthub-mcp": {
            "type": "stdio",
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "ghcr.io/alexw00/artifacthub-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "artifacthub-mcp": {
            "type": "stdio",
            "command": "docker",
            "args": [
                "run",
                "-i",
                "--rm",
                "ghcr.io/alexw00/artifacthub-mcp"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
