AI agents use create_group to create or update resources in Awslabs Amazon Sns Sqs — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Awslabs Amazon Sns Sqs environment.
The tool creates a new group, which is a Write operation—data is created and can be modified or deleted later. This is not Destructive (reversible), not Execute (no arbitrary code), not Read (causes side effects). Severity is medium because group creation in AWS messaging contexts could affect access control or billing if misused at scale, but lacks the critical impact of broader IAM or financial operations.
From the tool's definition Tool name 'create_group' indicates creation of a new group resource. The sibling tools include 'add_user_to_group' and 'add_inline_policy', suggesting this server manages IAM-like group entities.
Documented attack patterns abuse exactly the kind of access create_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 create_group:
{
"version": "1",
"default": "deny",
"tools": {
"create_group": {
"limits": [
{
"counter": "create_group_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_group stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

create_group. It is categorised as a Write tool in the Awslabs Amazon Sns Sqs MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for create_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.
create_group is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_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 create_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.
create_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.
