What vps_stop does on Hostinger
AI agents invoke vps_stop to trigger actions in Hostinger. 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 vps_stop is rated High
This tool executes a command against infrastructure and causes a real-world effect (stopping a running VPS), but the effect is reversible (the VPS can be restarted). It is not Destructive because data is not deleted or permanently lost. It is not Write because it does not create or modify data—it changes operational state.
From the tool's definition Tool name 'vps_stop' and description 'Stop a virtual machine' indicate an action that triggers an external operation (halting a VPS instance) whose effects are immediate and depend on which VPS is targeted.
Attacks that exploit this kind of access
The rule that runs vps_stop safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Hostinger, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For vps_stop, this is the rule to start with:
vps_stop 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Hostinger, apply this rule, and every vps_stop call is checked against it from then on.
Questions about vps_stop
Stop a virtual machine. It is categorised as a Execute tool in the Hostinger MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Hostinger MCP server in PolicyLayer and add a rule for vps_stop: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Hostinger. Nothing to install.
vps_stop is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the vps_stop rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for vps_stop. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
vps_stop is provided by the Hostinger MCP server (idugeni/hostinger-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
