AI agents call delete_access_key to permanently remove resources in Awslabs Amazon Sns Sqs — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting an access key is an irreversible operation that destroys authentication credentials. This qualifies as Destructive rather than Write (which is reversible) because deletion cannot be undone. The severity is high because an agent misusing this could lock users out of AWS services or cause authentication failures, though it is not financial in nature.
From the tool's definition Tool name 'delete_access_key' indicates irreversible deletion of an AWS access key, a security credential. The empty description prevents full certainty but the name strongly implies a destructive action that cannot be undone.
Documented attack patterns abuse exactly the kind of access delete_access_key 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 delete_access_key:
{
"version": "1",
"default": "deny",
"hide": [
"delete_access_key"
]
}delete_access_key disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

delete_access_key. It is categorised as a Destructive tool in the Awslabs Amazon Sns Sqs MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Awslabs Amazon Sns Sqs MCP server in PolicyLayer and add a rule for delete_access_key: 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.
delete_access_key is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_access_key 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 delete_access_key. 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.
delete_access_key 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.
