Returns a list of Timestream for InfluxDB DB instances filtered by status (case-insensitive).
AI agents call LsInstancesByStatus 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 queries and filters existing Timestream for InfluxDB DB instances by their status. It performs a list/filter operation that retrieves data without side effects. The 'case-insensitive' filter is a read-only parameter. No data is created, modified, deleted, or financial transactions are involved.
From the tool's definition Tool name 'LsInstancesByStatus' and description 'Returns a list' indicate a retrieval operation with no modification or deletion of data.
Attacks that exploit this kind of access
Returns a list of Timestream for InfluxDB DB instances 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 LsInstancesByStatus: 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.
LsInstancesByStatus 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 LsInstancesByStatus 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 LsInstancesByStatus. 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.
LsInstancesByStatus 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.
