AI agents call get_group to retrieve information from AWS without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a read-only operation that queries and returns IAM group configuration details. It has no capability to modify, delete, or execute actions. While IAM information is sensitive, the tool itself is non-destructive and poses minimal risk when used in isolation—an agent would need separate write/execute permissions to cause harm. Classified as Read with low severity.
From the tool's definition Tool retrieves comprehensive information about an IAM group including group members, attached policies, and inline policies. The description explicitly states it 'retrieves' and 'get' data with no side effects mentioned.
Documented attack patterns abuse exactly the kind of access get_group gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and AWS, and nothing reaches the server without passing your rules. This is the rule we recommend for get_group:
{
"version": "1",
"default": "deny",
"tools": {
"get_group": {}
}
}get_group is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a specific IAM group. This tool retrieves comprehensive information about an IAM group including group members, attached policies, and inline policies. Use this to get a complete picture of a group's configuration and membership. ## Usage Tips: - Use this after list_groups to get detailed information about specific groups - Review attached policies to understand group permissions - Check group members to see who has these permissions Args: group_name: The name of the IAM group Returns: GroupDetailsResponse containing comprehensive group information. It is categorised as a Read tool in the AWS MCP Server, which means it retrieves data without modifying state.
Register the AWS MCP server in PolicyLayer and add a rule for get_group: 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. Nothing to install.
get_group 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_group 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_group. 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_group is provided by the AWS MCP server (@awslabs/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from AWS, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
