List all available custom terminologies.
AI agents call list_terminologies 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.
This tool retrieves metadata about existing terminologies without creating, modifying, deleting, or executing any operations. It is a read-only operation with minimal security risk. Low severity because listing terminologies exposes configuration data but typically contains no sensitive credentials or personal information that would enable direct harm.
From the tool's definition Tool name 'list_terminologies' and description 'List all available custom terminologies' indicate a query/retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_terminologies 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 list_terminologies:
{
"version": "1",
"default": "deny",
"tools": {
"list_terminologies": {}
}
}list_terminologies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all available custom terminologies. 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 list_terminologies: 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.
list_terminologies 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 list_terminologies 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 list_terminologies. 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.
list_terminologies 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.
