获取ECS实例CPU使用率数据
AI agents call get_cpu_usage_data 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 monitoring metrics (CPU usage statistics) from Alibaba Cloud ECS instances. It performs a read-only query operation that returns monitoring data without creating, modifying, deleting, or executing any operations. No financial transactions or destructive actions are involved.
From the tool's definition Tool name 'get_cpu_usage_data' and description '获取ECS实例CPU使用率数据' (Get ECS instance CPU usage data) indicate data retrieval without modification or side effects.
Attacks that exploit this kind of access
获取ECS实例CPU使用率数据. It is categorised as a Read tool in the Alibaba Cloud Operations MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Alibaba Cloud Operations MCP Server MCP server in PolicyLayer and add a rule for get_cpu_usage_data: 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 Alibaba Cloud Operations MCP Server. Nothing to install.
get_cpu_usage_data 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 get_cpu_usage_data 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 get_cpu_usage_data. 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.
get_cpu_usage_data 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.
