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.

Why helm-mcp?

46 MCP tools covering every Helm CLI command (minus shell completion and help)
Dual Helm SDK support — Helm v3 and v4 via native Go SDK (not CLI wrappers)
Two transport modes — stdio (default) and Streamable HTTP, stateless by default
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 HTTP_PROXY, HTTPS_PROXY, NO_PROXY

Installation

Pre-built Binaries

Download the latest release for your platform from GitHub Releases:

Build from Source

Requires Go 1.27.2+.

git clone https://github.com/SCGIS-Wales/helm-mcp.git

cd helm-mcp make build

Docker

docker build -t helm-mcp .

docker run -v ~/.kube:/home/helmuser/.kube:ro helm-mcp --mode stdio

Python Package

pip install helm-mcp

See Python Package below for full details.

Quick Start

stdio mode (for Claude Code, Cursor, etc.)

helm-mcp --mode stdio

HTTP mode (Streamable HTTP)

helm-mcp --mode http

HTTP mode listens on 127.0.0.1:8080 by default. To accept remote clients, configure authentication (see Authentication) and bind explicitly, for example --addr 0.0.0.0:8080.

HTTP mode is stateless by default (MCP 2026-07-28): there is no initialize handshake and no Mcp-Session-Id header, so the server can sit behind a plain round-robin load balancer with no sticky sessions and no shared session store. Clients speaking an older protocol revision still work — the SDK negotiates down automatically.

If a client needs the legacy per-session behaviour:

helm-mcp --mode http --stateless=false

Removed in v0.2.0: `--mode sse`. The HTTP+SSE transport has been

deprecated by the MCP specification since 2025-03-26 and is formally

Deprecated under the 2026-07-28 feature lifecycle policy. Use

--mode http, which serves Streamable HTTP on the same address.

MCP Client Configuration

Claude Desktop

Add to ~/.claude/claude_desktop_config.json:

"mcpServers": { "helm": { "command": "helm-mcp", "args": ["--mode", "stdio"] } } }

Claude Code

claude mcp add helm -- helm-mcp --mode stdio

Cursor / Windsurf / VS Code

Add to your MCP server configuration:

"helm-mcp": { "command": "helm-mcp", "args": ["--mode", "stdio"] } }

Remote / HTTP Clients

Start the server in HTTP mode, then connect any MCP-compatible client to the endpoint:

helm-mcp --mode http

MCP endpoint: http://localhost:8080/mcp

MCP Protocol Support

helm-mcp implements MCP `2026-07-28` and negotiates down to earlier revisions (2025-11-25, 2025-06-18, 2025-03-26, 2024-11-05) for older clients, so upgrading the server does not require upgrading your client.

Feature	Status
Tools	Supported: 46 tools, each with a top level `title`, annotations and (where the result has a stable shape) an output schema
Progress	Supported. `helm_install`, `helm_upgrade`, `helm_uninstall`, `helm_rollback` and `helm_test` send `notifications/progress` heartbeats every 10 seconds when the request carries a progress token, so clients that reset their timeout on progress keep waiting for long `wait` operations
Cancellation	Supported. In HTTP mode a dropped request cancels the running tool call, as Ctrl+C cancels the `helm` CLI (`--propagate-cancellation=false` to let it finish)
Stateless transport	Supported and the default for `--mode http` (`--stateless=false` to opt out)
`server/discover`	Supported
Deterministic `tools/list` order	Supported — tools are returned sorted by name so clients and prompt caches keep hitting
Server instructions	Supported — the server explains version selection, cluster targeting and destructive-tool safety
Resources / Prompts	Not applicable — every Helm operation is a tool call
Tasks extension	Not implemented. Attractive for long `helm install --wait` runs, but client support is still thin. Tracked as a follow-up.
MRTR / Elicitation	Not implemented, deliberately. Helm tools take all their input as arguments, so there is no mid-call question to ask.
Roots / Sampling / Logging	Not implemented. All three are deprecated as of `2026-07-28` (SEP-2577).
HTTP+SSE transport	Removed in v0.2.0 — deprecated by the specification. Use `--mode http`.

Every tool carries MCP annotations so a client — or an agent deciding what to call — can tell a read at a glance from a change to your cluster.
