What the publisher says

From the Helm repository's README, as published. We do not edit it. Read it on GitHub

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.

Use natural language to manage your Kubernetes deployments. Connect helm-mcp to Claude, Cursor, VS Code, or any MCP-compatible client to install charts, manage releases, search repositories, and more — all through conversation.

  • Cloud provider ready — EKS, GKE, AKS kubeconfig formats work out of the box
  • Security first — Linux process hardening, credential memory zeroing, input validation, path traversal prevention
  • Python wrapper — FastMCP-based proxy that auto-discovers all tools
  • Forward proxy support — respects HTTPPROXY, HTTPSPROXY, NO_PROXY
