查询VPC列表
AI agents call describe_vpcs to retrieve information from Alibaba Cloud Operations MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists Virtual Private Cloud (VPC) configurations. The 'describe' pattern is standard for read-only operations across cloud platforms. It has no capability to create, modify, delete, or execute actions—it only queries existing infrastructure state. The blast radius of misuse is minimal; an agent could gather information about VPC configurations but cannot alter them.
From the tool's definition Tool name 'describe_vpcs' and description '查询VPC列表' (query VPC list) indicate a retrieval/query operation with no data modification or side effects.

describe_vpcs 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 describe_vpcs 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 describe_vpcs. 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.
describe_vpcs is provided by the Alibaba Cloud Operations MCP Server MCP server (radiumgu/alicloud-ops-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
