AWS Auto Scaling Group Capacity Calculator

AWS Auto Scaling Group Capacity Calculator MCP Connector for Claude

A+

Calculate exact instance requirements and scaling thresholds for AWS Auto Scaling Groups.

3 tools Official Updated Oct 1, 2026 Official Vinkius Partner

This MCP server provides deterministic tools to model AWS Auto Scaling Group (ASG) capacity. It helps engineers determine the exact number of instances needed to maintain a target CPU utilization based on request rates and processing times. Use calculate_fleet_capacity to find required instance counts, analyze_scaling_behavior to determine scale-out and scale-in thresholds, and predict_traffic_spikes to evaluate how your fleet handles sudden traffic surges. It bridges the gap between traffic metrics and infrastructure provisioning.

3 tools expose this connector's capabilities to your AI agent.

analyze_scaling_behavior

Calculates the thresholds for scaling actions and predicts how the fleet responds to traffic changes

calculate_fleet_capacity

Determines the required number of instances to meet the target CPU utilization for a specific traffic load

predict_traffic_spikes

Evaluates the robustness of the ASG configuration against sudden increases in traffic

How many instances do I need for 500 requests per second with 50ms processing time on a 2 vCPU instance at 70% target CPU?

You need 2 instances to meet the target CPU utilization.

What happens if my traffic doubles?

A doubling of traffic would require 4 instances to maintain the same target CPU utilization.

Check my scaling thresholds for a 50% target CPU.

Your scale-out threshold is 60% and your scale-in threshold is 30%.

The capacity is calculated by determining the relationship between total work (request rate multiplied by processing time) and available vCPU processing power, adjusted for your target CPU utilization.
