Lists services in a specific ECS cluster.
AI agents call list_ecs_services 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 and queries infrastructure metadata (ECS services) without modifying, executing, or deleting anything. It has no side effects and only returns information about existing cluster state. The server's read-only design and the context of sibling tools (list_*, get_*, check_*) further confirm this is a pure data retrieval operation.
From the tool's definition Tool name is 'list_ecs_services' and description states it 'Lists services in a specific ECS cluster.' The verb 'list' is explicitly a read operation. Server description confirms it is 'read-only'.
Attacks that exploit this kind of access
Lists services in a specific ECS cluster. 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_ecs_services: 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_ecs_services 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_ecs_services 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_ecs_services. 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_ecs_services 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.
