## Description

This MCP server provides a deterministic toolset for calculating exponential backoff delays with various jitter strategies. It helps agents manage retry logic by calculating specific delays using `calculate_retry_delay`, analyzing full retry lifecycles with `analyze_retry_schedule`, and estimating success probabilities with `estimate_success_confidence`. It supports 'none', 'full' (deterministic), and 'decorrelated' jitter types to prevent thundering herd problems in distributed systems.

## Tools

### analyze_retry_schedule
Provides a comprehensive overview of the entire retry lifecycle, including timing and success expectations

### calculate_retry_delay
Determines the specific delay duration for a single retry attempt based on the chosen jitter strategy

### estimate_success_confidence
Calculates the statistical confidence of completing a task within a specific number of attempts

## Prompt Examples

**Prompt:** 
```
Calculate the delay for the 3rd retry (attempt index 2) with an initial delay of 100ms, max delay of 1000ms, multiplier of 2.0, and full jitter.
```

**Response:** 
```
The calculated delay for attempt 2 is 400ms.
```

**Prompt:** 
```
What is the probability of success if each attempt has a 50% success rate and I have 3 attempts remaining?
```

**Response:** 
```
The cumulative success probability for 3 attempts at a 50% success rate is 87.5%.
```

**Prompt:** 
```
Analyze a schedule with 5 retries, 100ms initial delay, 2.0 multiplier, and a 2000ms deadline.
```

**Response:** 
```
The total cumulative wait time is 1500ms, and the deadline breach risk is low.
```

## Frequently Asked Questions

**How is 'full jitter' calculated?**
To ensure reproducibility, 'full jitter' uses a deterministic factor derived from the attempt number to scale the base delay.

**Can I analyze the risk of missing a deadline?**
Yes, using `analyze_retry_schedule`, you can identify the `deadlineBreachRisk` based on your cumulative wait time and provided deadline.

**What is the difference between 'none' and 'decorrelated' jitter?**
'none' provides a pure exponential increase, while 'decorrelated' jitter calculates the next delay based on the previous delay to smooth out retry spikes.
