列出所有阿里云ECS实例
AI agents call list_alibaba_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 retrieves and queries data about cloud instances without modifying, deleting, or executing operations on them. The 'list' operation is a standard read-only retrieval pattern. Even if an AI agent misuses it, the blast radius is limited to information disclosure rather than infrastructure changes or data destruction.
From the tool's definition Tool name contains 'list' (retrieval operation); description translates to 'List all Alibaba Cloud ECS instances' - a pure enumeration function with no side effects.
