WHAT IT DOES

What start_migration does on Vultr MCP

AI agents invoke start_migration 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_migration is rated High

Without a description, reliance is placed on the tool name and context. 'Start migration' implies executing an operation that transfers or moves infrastructure/data, which is an Execute category action (runs operations with external effects).

From the tool's definition Tool name 'start_migration' indicates initiation of a migration operation. In cloud infrastructure context (Vultr), migrations trigger external operations with side effects that depend on runtime conditions and cannot be easily reversed during execution.

RECOMMENDED RULE

The rule that runs start_migration 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_migration, this is the rule to start with:

start_migration Rate-limited

start_migration 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 Vultr MCP, apply this rule, and every start_migration call is checked against it from then on.
