Find ElastiCache clusters with low CPU utilization (<20%).
AI agents call find_underutilized_elasticache_clusters to retrieve information from AWS FinOps 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 monitoring data and identifies underutilized resources—a read-only analysis operation. It gathers information about ElastiCache cluster utilization to inform optimization decisions but does not modify, delete, or execute changes to AWS resources.
From the tool's definition Tool name 'find_underutilized_elasticache_clusters' and description 'Find ElastiCache clusters with low CPU utilization' indicate a query/search operation that retrieves and analyzes existing AWS resource metrics without modifying, deleting, or executing…

Find ElastiCache clusters with low CPU utilization (<20%). It is categorised as a Read tool in the AWS FinOps MCP Server MCP Server, which means it retrieves data without modifying state.
Register the AWS FinOps MCP Server MCP server in PolicyLayer and add a rule for find_underutilized_elasticache_clusters: 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 AWS FinOps MCP Server. Nothing to install.
find_underutilized_elasticache_clusters 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 find_underutilized_elasticache_clusters 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 find_underutilized_elasticache_clusters. 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.
find_underutilized_elasticache_clusters is provided by the AWS FinOps MCP Server MCP server (prashantgupta123/aws-pillar-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
