Helm MCP tools (5)

write = sends, deletes, buys or posts
  • get_dependenciesFree

    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://).

  • get_notesFree

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

  • get_valuesFree

    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://).

  • get_versionsFree

    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.

  • search_chartsFree

    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.

What the publisher says

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

mcp-helm

Give your AI assistant access to real Helm chart data. No more hallucinated values.yaml files.

What is this?

When you ask Claude, Cursor, or other AI assistants to help with Kubernetes deployments, they don't have access to Helm chart schemas. So they guess — and the guesses look plausible but don't match reality.

Without mcp-helm:

  • :x: Hallucinates field names that look right but don't exist
  • :x: Suggests stale or deprecated chart versions
  • :x: Wastes tokens on web fetches and guesswork

With mcp-helm:

  • :whitecheckmark: Queries actual Helm repositories for real chart data
  • :whitecheckmark: Gets the latest chart version automatically
  • :whitecheckmark: Correct configurations the first time

mcp-helm implements the Model Context Protocol (MCP) — a standard way for AI assistants to access external data sources.

Try It Now

Add this to your editor's MCP config to use our public instance (rate limited, no install required):

{
  "mcpServers": {
    "helm": {
      "type": "http",
      "url": "https://helm-mcp.kubedoll.com/mcp"
    }
  }
}

Then ask your AI: "What values can I configure for the bitnami/postgresql chart?"

Editor Setup

Claude Code

Edit ~/.claude/mcp.json:

{
  "mcpServers": {
    "helm": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "ghcr.io/kubedoll-heavy-industries/mcp-helm", "--transport=stdio"]
    }
  }
}

Claude Desktop

Edit ~/Library/Application Support/Claude/claudedesktopconfig.json (macOS) or %APPDATA%\Claude\claudedesktopconfig.json (Windows):

{
  "mcpServers": {
    "helm": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "ghcr.io/kubedoll-heavy-industries/mcp-helm", "--transport=stdio"]
    }
  }
}

Cursor

Edit MCP settings in Cursor's configuration:

{
  "mcpServers": {
    "helm": {
      "command": "docker",
      "args": ["run", "--rm", "-i", "ghcr.io/kubedoll-heavy-industries/mcp-helm", "--transport=stdio"]
    }
  }
}

VS Code + Continue

Add to your Continue config (~/.continue/config.json):

{
  "experimental": {
    "modelContextProtocolServers": [
      {
        "transport": {
          "type": "stdio",
          "command": "docker",
          "args": ["run", "--rm", "-i", "ghcr.io/kubedoll-heavy-industries/mcp-helm", "--transport=stdio"]
        }
      }
    ]
  }
}

Without Docker

If you prefer to run the binary directly, install mcp-helm and replace the Docker config with:

{
  "mcpServers": {
    "helm": {
      "command": "mcp-helm"
    }
  }
}

Does Helm MCP need an API key?
Not as far as the registry entry and our scan can tell: no credentials are declared or required.
Is Helm MCP maintained?
The last commit was 72 days ago (2026-08-24). The latest release is v0.1.4.
Is Helm MCP up?
100% of our last 28 checks got an answer. We check remote servers about four times a day.
What can I use instead of Helm MCP?
Servers from other publishers that do the same job: Excel MCP Server and jCodeMunch MCP server.
How does Helm MCP compare with other MCP servers?
safety score 88/100 (higher than 75% of 48,255 servers); tools 5 (the typical server has 7); tools that change things 0% (typical: 0%. Fewer write tools means less an agent can break). Full comparison.
