Connect Claude & ChatGPT to Hetzner Cloud

Ask your AI which servers are running, what is attached to a volume, or to reboot a server that hangs. It reads servers, volumes, networks, firewalls, load balancers, IPs and images in your Hetzner Cloud project. It can also power servers on and off, take snapshots and look up prices.

Connect Hetzner Cloud free

Free plan, no credit card. Takes about a minute.

Try asking

“Which servers are running in the project, and what are their IPs?”
The AI lists servers with status, type, location and public IP addresses.
“Reboot web-02.”
It finds the server and sends a graceful reboot through the operating system, then checks the action until it has finished.
“Take a snapshot of db-01 before I upgrade it.”
It creates a snapshot of the server's disk with your description. Snapshots are billed for storage.

What your AI can do

Servers

List and inspect servers, rename them or change labels, and power on, shut down, reboot, reset or power off.

Storage and images

See volumes, snapshots, backups and OS images, and create a snapshot or backup of a server.

Network and prices

Read firewalls, private networks, load balancers, floating and primary IPs, locations, server types and the price list.

“Which servers does the 'web' firewall apply to, and what does it allow?”
It reads the firewall with its rules and the servers it is applied to.
“What do the different server types cost?”
It lists server types with CPU, RAM, disk and price per location.
“Which volumes are not attached to any server?”
It lists volumes with size and location and points out the ones without a server.

Set up in three steps

1
Pick the app
Create a free HeyMyApps account and choose Hetzner Cloud from the app list.
2
Paste your key
Paste a Hetzner Cloud project API token. In the Hetzner Cloud Console open your project, go to Security > API tokens and click Generate API token. Choose Read or Read & Write and copy the token. It is shown only once and works for that one project.
3
Add the link to your AI
You get a personal MCP link. Add it to Claude, ChatGPT or Cursor:
1. Click your name, then Settings › Connectors › Add custom connector.
2. Paste your link as the Remote MCP server URL.
3. Switch it on from the + menu in a chat.

Questions

What can the AI do in Hetzner Cloud?

The AI can read servers, volumes, firewalls, networks, load balancers, floating and primary IPs, images, locations, server types and prices, and follow the progress of actions. It can rename servers and change labels, power servers on and off, reboot or reset them and create snapshots or backups.

Does the AI see my Hetzner Cloud API token?

No. Your Hetzner Cloud credentials are encrypted at rest and never shown to the AI. After you save them, they are not shown again, not even to you. The AI only sees the results of the tools it calls.

Can I control what the AI is allowed to do?

Yes. You choose which tools are switched on, so you can start read-only. A hard power-off or reset can lose unsaved data, and those actions can require your approval before they run. Every tool call is logged.

Does it work with ChatGPT?

Yes. In ChatGPT go to Settings › Apps & Connectors › Advanced and turn on Developer mode, then add your HeyMyApps link. Developer mode needs a paid ChatGPT plan: Plus, Pro, Business or Enterprise. The same link also works in Claude (Settings › Connectors › Add custom connector), Cursor and other MCP clients.

What does it cost?

HeyMyApps has a free plan with no credit card required. Paid plans bill per completed task. You also need your own Hetzner account.

Should I create a Read or a Read & Write token?

A Read token is enough if you only want the AI to look things up. Power actions, renaming and snapshots need Read & Write. Each token works for one project, so create one token per project you want the AI to reach.
