Helm MCP

An open-source MCP (Model Context Protocol) server that gives AI assistants full access to Helm - the Kubernetes package manager. Built with the native Helm Go SDK, supporting both Helm 3.x and 4.x in a single binary. Its 40 documented tools cover helm, repo, plugin, install. It runs locally over stdio via the published package.

People who work with helm, repo and plugin and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Go.

01 · Install Helm MCP

before you install - you'll need

Set HELM_MCP_OTEL_ENABLED, HELM_MCP_OTEL_EXPORTER, HELM_MCP_OTEL_SERVICE_NAME, HELM_MCP_MAX_RESPONSE_BYTES, HELM_MCP_OIDC_ISSUER, HELM_MCP_OIDC_AUDIENCE, HELM_MCP_REQUIRED_SCOPES, HELM_MCP_REQUIRED_ROLES, HELM_MCP_ALLOWED_CLIENTS, HELM_MCP_OIDC_JWKS_URL before connecting.

Claude Code

claude mcp add scgis-wales-helm-mcp -- uvx helm-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "scgis-wales-helm-mcp": {
      "command": "uvx",
      "args": [
        "helm-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

02 · Evidence

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · container (OCI image) - can be sandboxed away from your filesystem

license MIT - declared in the repository

pypi package helm-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.SCGIS-Wales is GitHub-verified and matches the repo owner

Does Helm MCP run locally?

Yes - it's a stdio server: it runs on your machine (via uvx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
