An MCP (Model Context Protocol) server that provides tools for interacting with Helm repositories and charts. This server enables AI assistants to query Helm repositories, retrieve chart information, and access chart values without. That is what the mcp helm mcp server brings to an AI assistant: the same capability, reachable through the Model Context Protocol rather than a separate app or dashboard.
The server publishes 9 tools. What each one is for:
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 chartget_latest_version_of_chart — Retrieves the latest version of a specific chartget_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)get_chart_dependencies — Retrieves the dependencies of a chart as defined in its Chart.yaml fileget_chart_images — Extracts container images used in a Helm chart by rendering templates and parsing KubernetesFlag — DescriptionAuthentication — The server supports authentication for both OCI registries and HTTP Helm repositoriesThe server ships on a container image as ghcr.io/zekker6/mcp-helm, so your MCP client can launch it on demand — there is no separate build step. Add the server block to your client's configuration, restart it, and the tools register themselves.
Configuration is passed through the environment: GITHUB_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Among the cloud and infrastructure options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. MCP Helm's toolset — list_repository_charts, list_chart_versions, get_latest_version_of_chart and 6 more — is a fair guide to whether it matches your workflow. It is maintained by zekker6; worth a glance at recent repository activity before you build anything load-bearing on it.
This entry was verified against MCP Helm's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
