WHAT IT DOES

What get_maintenance_updates does on Vultr MCP

RISK

Why get_maintenance_updates is rated Low

It is a read-only operation that has no side effects on infrastructure or data. The blast radius if misused is minimal—an agent could only access update information that is already available.

From the tool's definition Tool name 'get_maintenance_updates' and description 'Get available maintenance updates for a database' use the retrieval verb 'get' and indicate only querying/reading information about available updates, not applying or executing them.
