列出所有AWS EC2实例
AI agents call list_aws_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 enumerates AWS EC2 instances, which is a query/list operation that has no side effects. It does not create, modify, delete, or execute operations on instances. The blast radius of misuse is limited to information disclosure, which is a low-severity risk in isolation. The tool fits the Read category definition of retrieving or querying data with no side effects.
From the tool's definition Tool name 'list_aws_instances' and description '列出所有AWS EC2实例' (list all AWS EC2 instances) indicate data retrieval without modification or execution capabilities.
Attacks that exploit this kind of access
列出所有AWS EC2实例. It is categorised as a Read tool in the Cloud Manage MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Cloud Manage MCP Server MCP server in PolicyLayer and add a rule for list_aws_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_aws_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_aws_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_aws_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_aws_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.
