AI agents call list_billing_history to retrieve information from Vultr MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves historical billing information without modifying, deleting, or executing any operations. It is purely informational and carries minimal risk even if misused by an AI agent—exposure of billing history may be a privacy concern but does not enable financial transactions, data destruction, or code execution. Classified as Read with low severity.
From the tool's definition Tool name is 'list_billing_history' and description states 'List billing history for the specified number of days.' The verb 'list' and action of retrieving historical billing data indicates a read-only query with no side effects.

"default": "deny",
"tools": {
"list_billing_history": {}
}
