AI agents call hash_get_all 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 tool performs a read-only retrieval operation ('get all fields and values'). It accesses data without creating, modifying, or destructively removing anything. Even in the context of an SNS/SQS server, this appears to be a data query/inspection function. Blast radius is minimal—worst case, unintended information disclosure of non-sensitive metadata.
From the tool's definition Tool description: "Get all fields and values from hash." This retrieves data from a hash structure without modifying or deleting it. No side effects indicated.

Documented attack patterns abuse exactly the kind of access hash_get_all 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 hash_get_all:
{
"version": "1",
"default": "deny",
"tools": {
"hash_get_all": {}
}
}hash_get_all is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all fields and values from hash. 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 hash_get_all: 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.
hash_get_all 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 hash_get_all 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 hash_get_all. 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.
hash_get_all 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.
