About MCP Helm

The purpose of using MCP for Helm is to avoid making up format of values.yaml and contents of the charts when working with LLMs. Instead, the server provides a standardized way to access this information, making it easier for AI assistants to interact with Helm charts and repositories.

Features

  • list_repository_charts - Lists all charts available in a Helm repository (or chart name for OCI registries)

  • list_chart_versions - Lists all available versions/tags for a chart

  • get_latest_version_of_chart - Retrieves the latest stable (non-prerelease) version of a specific chart

  • get_chart_values - Retrieves the values file for a chart (latest version or specific version)

  • get_chart_contents - Retrieves the contents of a chart (including templates, values, and metadata), optionally filtered by file path glob patterns (for example, templates/**)

  • get_chart_dependencies - Retrieves the dependencies of a chart as defined in its Chart.yaml file

  • get_chart_images - Extracts container images used in a Helm chart by rendering templates and parsing Kubernetes manifests
