## Description

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.

## Tools

### 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

## Prompt Examples

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

**Response:** 
```
You need 2 instances to meet the target CPU utilization.
```

**Prompt:** 
```
What happens if my traffic doubles?
```

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

**Prompt:** 
```
Check my scaling thresholds for a 50% target CPU.
```

**Response:** 
```
Your scale-out threshold is 60% and your scale-in threshold is 30%.
```

## Frequently Asked Questions

**How is the required capacity calculated?**
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.

**What are the scaling thresholds?**
Scale-out is triggered when CPU utilization exceeds the target plus 10%, and scale-in is triggered when it falls below the target minus 20%.

**Can I predict how my fleet handles a traffic spike?**
Yes, using `predict_traffic_spikes`, you can evaluate if your current configuration can handle a 2x normal load or a 10x extreme spike.
