Find DynamoDB tables with low capacity utilization.
AI agents call find_underutilized_dynamodb_tables 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 and analyzes metrics about DynamoDB table utilization to inform cost optimization decisions. It performs no modifications, deletions, or execution of operations—only reads CloudWatch metrics and DynamoDB configuration data. The blast radius of misuse is minimal; an AI agent cannot cause harm by querying underutilization data.
From the tool's definition Tool name 'find_underutilized_dynamodb_tables' and description 'Find DynamoDB tables with low capacity utilization' indicate data retrieval and analysis only.
