List all inline policies for an IAM role.
AI agents call list_role_policies to retrieve information from Awslabs Amazon Sns Sqs without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a Read operation—it retrieves and queries IAM role policy information without modifying, deleting, or executing anything. However, severity is high because the data retrieved (IAM inline policies) can reveal sensitive security configuration, permission grants, and authorization details that could be exploited by an attacker to understand or escalate privileges within the AWS environment.
From the tool's definition The tool name is 'list_role_policies' and the description states it 'List all inline policies for an IAM role.' The verb 'list' indicates a read/query operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_role_policies gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Awslabs Amazon Sns Sqs, and nothing reaches the server without passing your rules. This is the rule we recommend for list_role_policies:
{
"version": "1",
"default": "deny",
"tools": {
"list_role_policies": {}
}
}list_role_policies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all inline policies for an IAM role. It is categorised as a Read tool in the Awslabs Amazon Sns Sqs MCP Server, which means it retrieves data without modifying state.
Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for list_role_policies: 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 Awslabs Amazon Sns Sqs. Nothing to install.
list_role_policies 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_role_policies 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_role_policies. 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_role_policies is provided by the Awslabs Amazon Sns Sqs MCP server (awslabs.amazon-sns-sqs-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Awslabs Amazon Sns Sqs, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
