gateway_delete
AI agents call gateway_delete to permanently remove resources in Amazon ElastiCache Memcached MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Delete operations are classified as Destructive because they remove data irreversibly and cannot be undone. Even without a description, the 'delete' verb in the tool name indicates this is a destructive action. Severity is high because deleting gateway infrastructure in a production ElastiCache cluster could disrupt service availability and data access.
From the tool's definition Tool name is 'gateway_delete' which uses the verb 'delete', indicating irreversible removal of data. The tool description is empty, preventing confirmation of scope, but the name alone strongly suggests deletion of AWS ElastiCache gateway resources.
Attacks that exploit this kind of access
gateway_delete. It is categorised as a Destructive tool in the Amazon ElastiCache Memcached MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Amazon ElastiCache Memcached MCP Server MCP server in PolicyLayer and add a rule for gateway_delete: 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 ElastiCache Memcached MCP Server. Nothing to install.
gateway_delete 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 gateway_delete 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 gateway_delete. 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.
gateway_delete is provided by the Amazon ElastiCache Memcached MCP Server MCP server (awslabs.memcached-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
