About
MCP server for the Hetzner Cloud API — servers, networks, volumes, firewalls, and more.
Security Report
The Hetzner MCP server is a straightforward Cloud API wrapper that requires a single API token supplied via environment variable, and its permissions (network_http, env_vars) match its stated purpose of managing Hetzner Cloud resources. Only the entry-point and split-registry files were provided, so the tool implementations, HTTP client, and dependency lockfile could not be reviewed, which limits confidence in the score. Caution is warranted because write operations can create billable resources, which the README itself notes. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity). Package verification found 1 issue.

Hetzner MCP Server
Manage Hetzner Cloud servers, networks, storage, DNS and load balancers from an MCP client. Requires Node.js 22.12 or newer.
Setup
Create an API token in the Hetzner Cloud Console. Use a read-only token for inspection; write operations can create billable resources.
For Claude Code:
claude mcp add --env HETZNER_API_TOKEN=your-token --transport stdio \
hetzner -- npx -y @lazyants/hetzner-mcp-server
For Claude Desktop and clients that accept mcpServers JSON:
{
"mcpServers": {
"hetzner": {
"command": "npx",
"args": ["-y", "@lazyants/hetzner-mcp-server"],
"env": { "HETZNER_API_TOKEN": "your-token" }
}
}
}
For a separate Storage Box token, also set HETZNER_STORAGE_API_TOKEN.
Otherwise, Storage Box tools use HETZNER_API_TOKEN.
Smaller servers
The default command exposes all tools. To load only one resource group, run a split command:
npx -y -p @lazyants/hetzner-mcp-server hetzner-mcp-networking
In a client configuration, replace args with:
["-y", "-p", "@lazyants/hetzner-mcp-server", "hetzner-mcp-networking"]
Other groups: servers, load-balancers, ips, storage, storage-boxes, config and dns.
Use the same hetzner-mcp- command prefix and token configuration.
Every server exposes the API reference at reference://hetzner/api.
