Available tools 5

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

charts

search_charts

List or search charts in a Helm repository. Provide a repository_url, then optionally filter by keyword (e.g. keyword='postgres'). Note: OCI registries (oci://) do not support browsing — for OCI you must already know the chart name, then call get_versions or get_values directly with that name.

dependencies

get_dependencies

Get chart dependencies (sub-charts). Each dependency entry includes the dependency's repository URL — feed that URL back into search_charts, get_versions, or get_values to inspect the dependency. Supports both HTTP/HTTPS repos and OCI registries (oci://).

notes

get_notes

Get chart NOTES.txt (post-install instructions). Supports both HTTP/HTTPS repos and OCI registries (oci://).

values

get_values

Get chart values.yaml with optional JSON schema. Uses depth limiting (default 2) to show structure without overwhelming context. Use path to drill into specific sections, depth=0 for full YAML. include_examples surfaces nearby commented YAML examples and requires path to be set. Supports both HTTP/HTTPS repos and OCI registries (oci://).

versions

get_versions

Get available versions of a chart (newest first). Supports both HTTP/HTTPS repos and OCI registries (oci://). Use this to confirm a chart exists before calling get_values, or to find a specific version to pin.

Helm MCP — questions

Answers built from our own checks of this server.

What can Helm MCP do?

It exposes 5 tools, read directly from the server on our last check. Among them: get_dependencies, get_notes, get_values, get_versions, search_charts. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is Helm MCP working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 310 ms. The bar chart above shows every period we have measured.

The registry lists Helm MCP as active — why does it not respond?

The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.

How do I connect Helm MCP?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does Helm MCP need an API key?

No. Helm MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 5 of them are readable on this page. This is what we observed, not what the docs claim.

Is Helm MCP open source?

The code is open source: it is published under the MIT licence, written in Go, 0 stars on GitHub and 4 open issues. The licence covers the code in the repository, not the hosted service at helm-mcp.kubedoll.com, which runs on its operator's own terms.
