AI agents call policy_get 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.
Policy retrieval is a read-only operation with no side effects. It queries existing policy configuration without modifying, executing, or deleting resources. The GET semantic strongly indicates a read operation. Confidence is moderate-to-high because the empty description lacks explicit confirmation, but the naming convention is clear.
From the tool's definition Tool name 'policy_get' follows RESTful GET convention indicating a retrieval operation. The server context (SNS/SQS management) suggests this retrieves policy documents. No description provided to confirm destructive or write operations.
Documented attack patterns abuse exactly the kind of access policy_get 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 policy_get:
{
"version": "1",
"default": "deny",
"tools": {
"policy_get": {}
}
}policy_get is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

policy_get. 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 policy_get: 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.
policy_get 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 policy_get 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 policy_get. 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.
policy_get 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.
