AI agents call describe_attachment to retrieve information from Amazon Translate MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'describe_*' naming pattern in AWS APIs typically denotes read-only operations that retrieve and return information about resources without side effects. Given no contrary evidence in the empty description, this falls under Read category. Severity is low because describing attachments poses minimal risk even if misused by an agent—it merely exposes information without enabling modification or deletion.
From the tool's definition Tool name 'describe_attachment' suggests retrieval of attachment metadata or details with no modification capability. The empty description prevents full certainty, but the 'describe' verb pattern indicates a read-only query operation.
Documented attack patterns abuse exactly the kind of access describe_attachment gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Amazon Translate MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for describe_attachment:
{
"version": "1",
"default": "deny",
"tools": {
"describe_attachment": {}
}
} describe_attachment is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

describe_attachment. It is categorised as a Read tool in the Amazon Translate MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon Translate MCP Server MCP server in PolicyLayer and add a rule for describe_attachment: 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 Amazon Translate MCP Server. Nothing to install.

Yes. Add a rate_limit block to the describe_attachment 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 describe_attachment. 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.
describe_attachment is provided by the Amazon Translate MCP Server MCP server (awslabs.amazon-translate-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
