AI agents use create_agent_runtime 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 'create' prefix indicates a Write operation—reversible infrastructure provisioning rather than destructive deletion or irreversible changes. No evidence of financial commitments, code execution, or data deletion. Medium severity reflects typical cloud resource creation risks (cost, permission issues, misconfiguration), though exact capabilities are unclear due to missing description.
From the tool's definition Tool name 'create_agent_runtime' suggests creation of a runtime agent within AWS services. The server context (Amazon SNS/SQS MCP) implies this creates messaging/service infrastructure. Description is empty, limiting evidence precision.
Documented attack patterns abuse exactly the kind of access create_agent_runtime 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_agent_runtime:
{
"version": "1",
"default": "deny",
"tools": {
"create_agent_runtime": {
"limits": [
{
"counter": "create_agent_runtime_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_agent_runtime 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_agent_runtime. 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_agent_runtime: 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_agent_runtime 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_agent_runtime 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_agent_runtime. 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_agent_runtime 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.
