What is MCP Helm Server?

The MCP Helm Server is a Model Context Protocol server that provides tools for AI assistants to query Helm repositories and charts without requiring a local Helm installation. Its purpose is to avoid LLMs making up the format of values.yaml and chart contents, offering a standardized way to access this information.

How to use MCP Helm Server?

Install it via Docker, a pre-built binary from the releases page, Mise, go install, or building from source. Then configure your MCP client to connect using the server’s SSE mode (e.g., -mode=sse) or Streamable HTTP mode. Authentication credentials for private repositories can be passed with command-line flags like -username, -password-file, and -registry-credentials.

Key features of MCP Helm Server

List all charts in a Helm repository (list_repository_charts)
List all available versions for a chart (list_chart_versions)
Get the latest version of a chart (get_latest_version_of_chart)
Retrieve a chart’s values file (get_chart_values)
Retrieve full chart contents including templates and metadata (get_chart_contents)
Extract chart dependencies from Chart.yaml (get_chart_dependencies)
Extract container images used in a chart (get_chart_images)
Supports both HTTP Helm repositories and OCI registries

Use cases of MCP Helm Server

An AI assistant queries which versions of a Helm chart are available in a repository
A developer retrieves the values.yaml file for a specific chart version without local Helm
A CI pipeline checks for updated chart dependencies before deploying
An LLM extracts container images from a chart to verify or document resource usage

FAQ from MCP Helm Server

What makes MCP Helm Server different from other Kubernetes MCP servers?

This server is strictly for working with Helm repositories and charts. It does not interact with other Kubernetes resources; for those, consider a separate Kubernetes-focused MCP server.

What are the runtime requirements?

If building from source, Go 1.24.3 is required. Otherwise, the server can run via Docker or using a pre-built binary, with no external Helm installation needed.

Where does the server fetch data from?

It fetches data from Helm repositories (HTTP or OCI registries) specified in tool calls. No local chart storage is required; data is pulled on demand.

How do I authenticate to private repositories?

Authentication is configured via command-line flags. For HTTP repos and OCI registries not covered by a credentials file, use -username and -password-file. For OCI registries, you can also pass -registry-credentials (a Docker-style config.json). TLS/mTLS flags are also available.

Is there a public instance for testing?

Yes, a publicly available instance is hosted at https://mcp-helm.zekker.dev/mcp for testing without installation.
