Servers, volumes, networks, firewalls, load balancers, pricing and safe power operations. Hosted by usefulapi — connect from Claude, Cursor, or any MCP client.
Team and Enterprise: an Owner adds the connector for the organization first.
Run this command, then run /mcp in Claude Code to log in:
Add to Cursor or add this to ~/.cursor/mcp.json:
{
"mcpServers": {
"hetzner-cloud": {
"url": "https://hetzner-cloud.usefulapi.io/mcp"
}
}
}Add to VS Code or add this to .vscode/mcp.json:
{
"servers": {
"hetzner-cloud": {
"type": "http",
"url": "https://hetzner-cloud.usefulapi.io/mcp"
}
}
}Other MCP clients (Windsurf, Cline, Zed and more): add the URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser. Do not add an Authorization header: see Before you connect.
The login page asks for your Hetzner Cloud API token.
Create one in the Hetzner Cloud Console → your project → Security → API tokens. Your token is used only to call the API on your behalf and to derive a private account id; it is never shown to anyone.
Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Hetzner Cloud API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
Turn on the Hetzner Cloud connector, then ask in plain words. The AI picks the tools.
| Tool | Type | What it does |
|---|---|---|
hetzner_list_servers | read | List servers List the servers in the token's project, optionally filtered by name, status or a label selector. Hetzner Cloud: GET /servers. |
hetzner_get_server | read | Get one server Fetch a single server with its type, image, IPs, volumes, networks and protection flags. Hetzner Cloud: GET /servers/{id}. |
hetzner_get_server_metrics | read | Get server metrics Fetch CPU, disk or network time series for one server over a window. Hetzner Cloud: GET /servers/{id}/metrics. |
hetzner_list_server_types | read | List server types List the available server types with their cores, memory, disk and hourly and monthly prices — read this before creating a server. Hetzner Cloud: GET /server_types. |
hetzner_list_images | read | List images List OS images, snapshots and backups you can boot or restore from. Hetzner Cloud: GET /images. |
hetzner_list_locations | read | List locations List the datacentre locations (city, country, network zone) servers can run in. Hetzner Cloud: GET /locations. |
hetzner_get_pricing | read | Get pricing Fetch the full price list for the project's currency — server types, volumes, traffic, floating IPs, load balancers and backups. Hetzner Cloud: GET /pricing. |
hetzner_get_action | read | Get one action Fetch the status of one asynchronous action. Every write tool here returns an action id — poll it with this to see whether the operation finished. Hetzner Cloud: GET /actions/{id}. |
hetzner_list_volumes | read | List volumes List block-storage volumes, their size and which server they are attached to. Hetzner Cloud: GET /volumes. |
hetzner_get_volumes | read | Get one volume Fetch a single resource by id. Hetzner Cloud: GET /volumes/{id}. |
hetzner_list_networks | read | List networks List private networks, their IP ranges, subnets and routes. Hetzner Cloud: GET /networks. |
hetzner_get_networks | read | Get one network Fetch a single resource by id. Hetzner Cloud: GET /networks/{id}. |
hetzner_list_firewalls | read | List firewalls List firewalls, their rules and which resources they are applied to. Hetzner Cloud: GET /firewalls. |
hetzner_get_firewalls | read | Get one firewall Fetch a single resource by id. Hetzner Cloud: GET /firewalls/{id}. |
hetzner_list_load_balancers | read | List load balancers List load balancers, their services, targets and health status. Hetzner Cloud: GET /load_balancers. |
hetzner_get_load_balancers | read | Get one load balancer Fetch a single resource by id. Hetzner Cloud: GET /load_balancers/{id}. |
hetzner_list_ssh_keys | read | List SSH keys List the SSH public keys available to inject when creating a server. Hetzner Cloud: GET /ssh_keys. |
hetzner_get_ssh_keys | read | Get one SSH key Fetch a single resource by id. Hetzner Cloud: GET /ssh_keys/{id}. |

hetzner_get_primary_ips | read | Get one primary IP Fetch a single resource by id. Hetzner Cloud: GET /primary_ips/{id}. |
hetzner_list_certificates | read | List certificates List TLS certificates, managed or uploaded, and their expiry. Hetzner Cloud: GET /certificates. |
hetzner_get_certificates | read | Get one certificate Fetch a single resource by id. Hetzner Cloud: GET /certificates/{id}. |
hetzner_create_server | write | Create a server Provision a new server. THIS STARTS BILLING: the chosen server type is charged by the hour from the moment it boots. Call hetzner_list_server_types first to see prices, and hetzner_list_images for a bootable image. Hetzner Cloud: POST /servers. |
hetzner_poweron_server | write | Power on a server Power on a stopped server. Returns an action id — poll it with hetzner_get_action. Hetzner Cloud: POST /servers/{id}/actions/poweron. |
hetzner_shutdown_server | write | Shut down a server Ask the guest OS to shut down gracefully via ACPI. Prefer this over a hard power-off. Note that a stopped server still costs money — only deleting it stops the bill. Hetzner Cloud: POST /servers/{id}/actions/shutdown. |
hetzner_reboot_server | write | Reboot a server Reboot a server gracefully via ACPI. Hetzner Cloud: POST /servers/{id}/actions/reboot. |
hetzner_create_image_from_server | write | Snapshot a server to an image Create a snapshot image from a server's disk — the safe thing to do BEFORE a risky change. Snapshots are billed for the space they use. Hetzner Cloud: POST /servers/{id}/actions/create_image. |
hetzner_enable_server_backup | write | Enable server backups Turn on automatic backups for a server. This adds roughly 20% to the server's price. Hetzner Cloud: POST /servers/{id}/actions/enable_backup. |
hetzner_disable_server_backup | write | Disable server backups Turn off automatic backups for a server. Existing backups are DELETED. Hetzner Cloud: POST /servers/{id}/actions/disable_backup. |
hetzner_change_server_protection | write | Change a server's protection Turn deletion and rebuild protection on or off for a server. Turning protection ON is the safest write in this server. Hetzner Cloud: POST /servers/{id}/actions/change_protection. |
hetzner_cloud_usage_status | Usage status (free-tier meter) Report the caller's current free-tier usage this month: calls used, monthly limit, remaining, and whether the cap is reached. Read-only; does not count against the meter. | |
hetzner_cloud_request_feature | Request a missing feature Tell usefulapi that the user needs something the Hetzner Cloud tools cannot do yet (a missing tool, field or filter). Call it only when the user asks for something none of the tools can do, and tell the user that you send the request. Do not call it for errors or for normal requests. Do not include personal data, credentials or customer records. Stored with the product name and the client type (for example Claude or Cursor), without the user's account. At most 5 requests per day. Does not count against the meter. | |
hetzner_cloud_upgrade | Upgrade to Pro (unlimited) Subscribe to the Pro plan for UNLIMITED Hetzner Cloud tool calls (the free tier caps monthly usage). Choose monthly ($9/month) or yearly ($90/year — 2 months free) billing. Returns a Stripe Checkout link to open in your browser; after payment your account upgrades automatically. Does not count against the meter. | |
hetzner_cloud_cancel_subscription | Cancel the Pro subscription Cancel the caller's Hetzner Cloud Pro subscription at the end of the paid period (no refund for the current period; unlimited calls continue until then, then the free tier applies). Requires confirm: true. Run hetzner_cloud_upgrade later to undo the cancel before the period ends. Does not count against the meter. |
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 100 tool calls / month |
| Pro | $9/mo · $90/yr | Unlimited |
Pro covers this Hetzner Cloud server only. Subscribe with hetzner_cloud_upgrade (it returns a Stripe Checkout link). Cancel any time with hetzner_cloud_cancel_subscription: Pro continues to the end of the paid period, with no refund for the current period, and running hetzner_cloud_upgrade before then undoes the cancel. Or write to [email protected].
No. usefulapi is an independent service. It is not affiliated with or endorsed by Hetzner Cloud. The server calls the Hetzner Cloud API with your own Hetzner Cloud access, so it sees only the data that your account can see.
The login page asks for your Hetzner Cloud API token. See Before you connect for where to find it.
No. Add only the URL. Do not add an Authorization header or an API key to the client config. The server signs you in with OAuth: the login page asks for your Hetzner Cloud API token. If the config has such a header, remove it: some clients then send that header instead of the login token, and every call fails with 401.
The login stores them encrypted in the authorization grant of your connection. The server uses them to call the Hetzner Cloud API for you and to derive a private account id for usage metering. usefulapi does not show them on any page or in any reply. To stop all access, remove the connector and change or delete these credentials in Hetzner Cloud.
Yes, if you approve it. 8 of the 32 Hetzner Cloud tools can create or change data. The other 24 are marked read-only. Most MCP clients ask you to approve a tool call before it runs.
The Free plan gives 100 tool calls / month. Pro costs $9/mo or $90/yr, with unlimited tool calls, for this Hetzner Cloud server only. Run hetzner_cloud_usage_status to see how many calls you used.
Ask the AI to run hetzner_cloud_upgrade: it returns a Stripe Checkout link. To cancel, run hetzner_cloud_cancel_subscription. Pro continues to the end of the paid period.
Tell the AI what you wanted to do. It can send the request with hetzner_cloud_request_feature. We store the text with the server name, the type of AI client and the tool you tried, not with your account, and read every request when we plan new tools. You can send up to 5 requests per day.
Any client that supports remote MCP servers (Streamable HTTP) with OAuth login: Claude (web and desktop), Claude Code, Cursor, VS Code, Windsurf and others.
This is a Model Context Protocol endpoint — meant to be connected from an AI client, not opened in a browser. An invalid_token response at the URL is the auth gate working as designed; clients authenticate automatically.
