Returns a list of Timestream for InfluxDB DB clusters filtered by status (case-insensitive).
AI agents call ListClustersByStatus 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.
This tool retrieves and filters existing cluster information without creating, modifying, or deleting any resources. It is a read-only operation that queries the state of Timestream for InfluxDB clusters. The blast radius of misuse is minimal—an attacker could only discover cluster information, not compromise or alter infrastructure.
From the tool's definition Tool name 'ListClustersByStatus' and description 'Returns a list of... clusters filtered by status' indicate a query/list operation with no modification or deletion of data.
Attacks that exploit this kind of access
Returns a list of Timestream for InfluxDB DB clusters filtered by status (case-insensitive). 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 ListClustersByStatus: 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.
ListClustersByStatus 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 ListClustersByStatus 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 ListClustersByStatus. 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.
ListClustersByStatus 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.
