AI agents call get_group 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.
The 'get_group' naming pattern strongly suggests a read/retrieval operation. Although the description is empty (lowering confidence slightly), the tool name semantics and the fact it appears alongside read operations like 'list' suggest it queries existing data without side effects. No evidence of write, delete, or execute capabilities.
From the tool's definition Tool name 'get_group' with no description provided. Based on naming convention and context of an AWS/messaging MCP server, this tool retrieves group information without modifying data.
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 Awslabs Amazon Sns Sqs, 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_group. 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 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 Awslabs Amazon Sns Sqs. 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 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.
