hetzner-mcp-server

MCP server for the Hetzner Cloud API. Manage servers, networks, volumes, firewalls, load balancers, and more through the Model Context Protocol.

185 tools across 15 resource domains, with 9 entry points so you can pick the right server for your MCP client's tool limit. A read-only API-reference Resource (reference://hetzner/api) is also exposed on every entry point.

Installation

npm install -g @lazyants/hetzner-mcp-server

Or run directly:

npx @lazyants/hetzner-mcp-server

Configuration

Set your Hetzner Cloud API token:

export HETZNER_API_TOKEN=your-token-here

Get a token from the Hetzner Cloud Console under Security > API Tokens.

The Storage Box tools call a separate host (https://api.hetzner.com/v1). They use HETZNER_STORAGE_API_TOKEN if set, otherwise fall back to HETZNER_API_TOKEN, so a single token keeps working. Set HETZNER_STORAGE_API_TOKEN only if you scope Storage Box access to a dedicated token:

export HETZNER_STORAGE_API_TOKEN=your-storage-token-here  # optional

Entry Points

Use split servers to reduce context size — pick only the splits you need.

Security

• Never commit your API token to version control
• Use read-only tokens when you only need to list/get resources
• Create and delete tools cost real money — Hetzner bills for provisioned resources
• The server handles rate limiting automatically (3,600 requests/hour, exponential backoff on 429)
