列出所有Vultr实例
AI agents call list_vultr_instances to retrieve information from Cloud Manage MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and enumerates cloud instances for monitoring/identification purposes. It performs no write, deletion, execution, or financial operations. The operation is read-only information retrieval, consistent with the sibling tools (get_*_info, get_*_monitoring) on this server.
From the tool's definition Tool name 'list_vultr_instances' and description '列出所有Vultr实例' (list all Vultr instances) indicate a query/list operation that retrieves instance information without modifying state.

Register the Cloud Manage MCP Server MCP server in PolicyLayer and add a rule for list_vultr_instances: 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 Cloud Manage MCP Server. Nothing to install.
list_vultr_instances is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the list_vultr_instances 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 list_vultr_instances. 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.
list_vultr_instances is provided by the Cloud Manage MCP Server MCP server (rainhan99/cloud_manage_mcp_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
