Lists Elastic IPs that are not associated with any instance.
AI agents call list_unassociated_eips to retrieve information from AWS 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 information about unassociated Elastic IP addresses without creating, modifying, deleting, or executing any operations. It is a pure read/query operation with minimal blast radius if misused by an agent — the worst outcome would be information disclosure about unused cloud resources. The read-only nature of the parent server and the list/query semantics confirm Read category classification.
From the tool's definition Tool name is 'list_unassociated_eips' and description states it 'Lists Elastic IPs' — a query operation with no side effects. The server is described as 'read-only' and provides 'secure, AI-ready access to AWS infrastructure data.'
Attacks that exploit this kind of access
Lists Elastic IPs that are not associated with any instance. It is categorised as a Read tool in the AWS MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP Server MCP server in PolicyLayer and add a rule for list_unassociated_eips: 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 AWS MCP Server. Nothing to install.
list_unassociated_eips 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_unassociated_eips 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_unassociated_eips. 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_unassociated_eips is provided by the AWS MCP Server MCP server (sergiosediq/aws-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
