The Lambda Performance MCP Server is a Node.js-based tool that provides comprehensive analysis, monitoring, and optimization of AWS Lambda functions. It enables you to:
Analyze performance metrics including cold starts, duration, memory usage, error rates, and invocation counts for individual functions
Track cold start patterns and frequency to identify optimization opportunities
Get targeted optimization recommendations for cold start performance, memory allocation, execution duration, and cost reduction
Compare performance metrics (duration, cold starts, errors, invocations, cost) across multiple Lambda functions over specified time ranges
List all Lambda functions in your AWS account with optional basic performance metrics
Analyze memory utilization and provide right-sizing recommendations to optimize resource allocation
Perform cost analysis for individual functions or across your entire account to identify cost optimization opportunities
Monitor real-time performance metrics and receive alerts for ongoing Lambda function monitoring
Provides comprehensive performance analysis, cold start tracking, memory utilization monitoring, cost analysis, and optimization recommendations for AWS Lambda functions through CloudWatch metrics and logs
