reset_server · Hcloud MCP: Risk & Policy

WHAT IT DOES

What reset_server does on Hcloud

AI agents invoke reset_server to trigger actions in Hcloud. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why reset_server needs a policy

A hard reset is an abrupt power-cycle of a running server. It is not a graceful reboot and can cause data corruption or service disruption, but it does not irreversibly delete data. It falls under Execute (triggers external infrastructure operation) rather than Destructive, since the server and its data remain intact after the reset.

From the tool's definition 'Reset a server (hard)' — a hard reset forcibly restarts a server without graceful shutdown, triggering an external operation on cloud infrastructure

Verdict

reset_server Rate-limited

reset_server stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
