ListAHORunCaches
AI agents call ListAHORunCaches to retrieve information from Amazon ElastiCache Memcached MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
List operations retrieve and enumerate resource information without side effects. The tool name strongly suggests read-only access to cache resources within ElastiCache. While the empty description prevents absolute certainty, the 'List' prefix is a strong signal of read category. Severity is low because listing cache metadata poses minimal risk even if invoked inappropriately.
From the tool's definition Tool name 'ListAHORunCaches' indicates a list operation on caches. The tool prefix 'List' typically denotes read-only enumeration of resources without modification. Description is empty, reducing confidence slightly.
Attacks that exploit this kind of access
ListAHORunCaches. It is categorised as a Read tool in the Amazon ElastiCache Memcached MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Amazon ElastiCache Memcached MCP Server MCP server in PolicyLayer and add a rule for ListAHORunCaches: 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.
ListAHORunCaches 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 ListAHORunCaches 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 ListAHORunCaches. 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.
ListAHORunCaches 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.
