WHAT IT DOES

What start_bare_metal_server does on Vultr MCP

AI agents invoke start_bare_metal_server to trigger actions in Vultr MCP. 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.

RISK

Why start_bare_metal_server is rated High

Starting a bare metal server is an Execute operation because it triggers an external infrastructure action that changes system state. While not destructive or financial, it has high blast radius: an AI agent could start expensive compute resources incurring charges, or start servers that disrupt production workloads.

From the tool's definition Tool name is 'start_bare_metal_server' and description states it 'Start a bare metal server.' This triggers an external operation (starting cloud infrastructure) whose effects depend on which server is targeted.

RECOMMENDED RULE

The rule that runs start_bare_metal_server safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vultr MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For start_bare_metal_server, this is the rule to start with:

start_bare_metal_server Rate-limited

start_bare_metal_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.
