获取ECS实例磁盘使用率数据
AI agents call get_disk_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 from Alibaba Cloud ECS instances. It performs data retrieval only with no side effects, no resource modifications, and no irreversible actions. Reading system metrics and usage data is inherently a Read-category operation with low severity risk.
From the tool's definition Tool description translates to 'Get ECS instance disk usage data'. The function retrieves monitoring/metrics data about disk utilization without modifying any resources. This is a pure query operation that returns observability data from CloudMonitor.
Attacks that exploit this kind of access
获取ECS实例磁盘使用率数据. 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_disk_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_disk_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_disk_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_disk_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_disk_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.
