## Description

This MCP server provides deterministic probability modeling for gacha loot box systems. It helps users navigate complex pity mechanics common in mobile games. Use `calculate_single_pull_odds` to find the immediate chance of success, `calculate_cumulative_projections` to estimate total currency costs and success rates over multiple pulls, or `check_pity_status` to determine if a featured character is guaranteed via the 50/50 mechanic.

## Tools

### calculate_single_pull_odds
Determines the specific probability of success for the very next pull based on the current state of the pity counter

### check_pity_status
Evaluates the user's current standing regarding "guaranteed" featured items (the 50/50 mechanic)

### calculate_cumulative_projections
Projects the likelihood of success and resource requirements over a user-defined number of future pulls

## Prompt Examples

**Prompt:** 
```
What is my chance of getting a 5-star on my next pull if I am at 74 pity, the base rate is 0.6%, soft pity starts at 74, hard pity is 90, and the increment is 6%?
```

**Response:** 
```
Your probability of success on the next pull is 6.6%.
```

**Prompt:** 
```
How much will it cost to do 50 more pulls if each pull costs 160 gems, with a base rate of 0.6%, soft pity at 74, hard pity at 90, and increment of 6%? I am currently at 0 pity.
```

**Response:** 
```
The total cost for 50 pulls is 8,000 gems, and your cumulative probability of success is approximately 32.8%.
```

**Prompt:** 
```
Am I guaranteed the featured character next time I hit a 5-star?
```

**Response:** 
```
Yes, you are currently in a Guaranteed state.
```

## Frequently Asked Questions

**How do I calculate my next pull chance?**
You can use the `calculate_single_pull_odds` tool. Provide your current pity counter, the base rate, and the soft/hard pity thresholds to get the exact probability.

**Can I estimate how much currency I need for a banner?**
Yes, use `calculate_cumulative_projections` to see the total cost and the cumulative probability of success for a specific number of pulls.

**What is the 50/50 mechanic?**
The 50/50 mechanic determines if your next high-rarity pull is the featured character. You can use `check_pity_status` to see if you are currently in a 'Guaranteed' state.
