Can I use Hetzner Cloud as a CLI?

Yes. KosmoKrator exposes a Hetzner Cloud CLI through kosmo integrations:call and the provider shortcut command. Commands can return JSON for scripts, CI, and coding agents.

Can I expose Hetzner Cloud through MCP?

Yes. The KosmoKrator MCP gateway can expose selected Hetzner Cloud tools to clients such as Claude Code, Cursor, Codex, and other MCP-compatible tools.

Where are Hetzner Cloud credentials stored?

Hetzner Cloud credentials are configured in KosmoKrator's local integration settings and reused by CLI, Lua, and MCP gateway surfaces.

Can I deny write access for Hetzner Cloud MCP tools?

Yes. Start the gateway with --write=deny for read-only clients, or use ask/allow only for trusted workspaces.

Connect Hetzner Cloud to Claude Agent SDK

Give Claude Agent SDK workflows access to KosmoKrator integrations through a local MCP server.

Add a KosmoKrator stdio MCP server to the Claude Agent SDK options. The gateway is local, scoped to this integration, and starts with --write=deny so Claude Agent SDK can inspect read-capable tools without receiving write access by default.

Hetzner Cloud MCP Config for Claude Agent SDK

Use a narrow integration list so the agent does not load unrelated tools.

{
  "mcpServers": {
    "kosmokrator-hetzner": {
      "type": "stdio",
      "command": "kosmo",
      "args": [
        "mcp:serve",
        "--integration=hetzner",
        "--write=deny"
      ]
    }
  }
}

Run the Gateway Manually

kosmokrator mcp:serve --integration=hetzner --write=deny

Why Use KosmoKrator Here

Scoped tools

Expose only Hetzner Cloud instead of a broad multi-service tool list.

Local credentials

Reuse credentials already configured for the KosmoKrator CLI and Lua runtime.

Write policy

Start read-only, then opt into ask or allow for trusted workspaces.
