Servers, volumes, networks, firewalls, load balancers, pricing and safe power operations. Hosted by usefulapi: connect it to Claude, ChatGPT, Cursor or any MCP client.
Turn on the Hetzner Cloud connector, then ask in plain words. The AI picks the tools.
For developers and sysadmins who run servers, volumes and networks on Hetzner Cloud.
The AI lists servers with their status and type, then reads the price list and server types. You get a monthly cost view per server.
The AI reads CPU, disk or network time series for one server over a time window. You can spot load peaks or an idle machine.
The AI lists firewalls with their rules and applied resources, private networks with subnets and routes, and load balancers with targets and health. You see how your setup connects.
The AI lists volumes with their size and attached server, floating IPs with their server, and certificates with their expiry. It helps you find unused or expiring items.
The AI creates a snapshot image of a server's disk, and turns automatic backups on or off. Snapshots and backups add cost, and turning backups off deletes existing backups.
Changes dataThe AI powers on a stopped server, reboots it, or shuts it down gracefully, and can turn deletion and rebuild protection on or off. Each action returns an action id to check. A stopped server still costs money.
Changes dataThe 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.
Team and Enterprise: an Owner adds the connector for the organization first.
No Add custom MCP server option? It depends on your account or workspace settings: see OpenAI's guide.
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"
}
}
} Run these commands. The second one opens the login page:
Windsurf, Cline, Zed and other MCP clients: add this URL as a remote MCP server (Streamable HTTP). The client then opens the login page in your browser.
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.
| Plan | Price | Limit |
|---|---|---|
| Free | $0 | 50 tool calls / month |
| Pro | $9/mo · $90/yr | 10,000 tool calls / month |
| Pro+ | $39/mo · $390/yr | 100,000 tool calls / month |
Each paid plan covers this Hetzner Cloud server only. Ask your AI to run hetzner_cloud_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with hetzner_cloud_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with hetzner_cloud_upgrade before then undoes the cancel. Or write to [email protected].

Look at CPU, disk or network use of a server. Review firewalls, networks and load balancers. Check volumes, floating IPs and TLS certificate expiry. Snapshot a server or change its backups. Change a server's power state or protection. See what you can do for the details.
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.
Yes. In Claude, add this server's URL as a custom connector. In ChatGPT, add it as a custom MCP server in Plugins. Then log in once. Cursor, VS Code, Claude Code and Codex work too. See the setup steps.
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 50 tool calls / month. Pro costs $9/mo or $90/yr, with 10,000 tool calls / month. Pro+ costs $39/mo or $390/yr, with 100,000 tool calls / month. Each subscription covers this Hetzner Cloud server only. Cancel any time: your paid plan then runs to the end of the paid period. Run hetzner_cloud_usage_status to see how many calls you used.
Ask the AI to run hetzner_cloud_upgrade and choose Pro or Pro+, billed monthly or yearly: it returns a Stripe Checkout link. If you already have Pro, ask to change it to Pro+. After you confirm, your existing subscription changes in place, keeps its billing interval and charges the price difference for the rest of the period immediately. To cancel, run hetzner_cloud_cancel_subscription. Your paid plan 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, ChatGPT, Codex, 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.
