## Description

This MCP server provides biochemical modeling for wine fermentation. It allows AI agents to predict pyruvic acid accumulation using `get_pyruvic_acid_accumulation`, calculate the potential for color-stabilizing vitisin complexes via `predict_vitisin_potential`, and assess long-term pigment permanence with `calculate_color_stability_index`. It also includes `evaluate_fermentation_environment` to monitor metabolic health and thiamine-related bottlenecks.

## Tools

### calculate_color_stability_index
Predicts the long-term color stability of the wine based on pigment formation and environmental degradation

### evaluate_fermentation_environment
Assesses how the current fermentation conditions will impact the overall metabolic pathway

### get_pyruvic_acid_accumulation
Predicts the total amount of pyruvic acid that will accumulate during the fermentation process

### predict_vitisin_potential
Calculates the potential for creating color-stabilizing vitisin complexes

## Prompt Examples

**Prompt:** 
```
Predict the pyruvic acid concentration for yeast strain 'Standard-01' at 22 degrees Celsius with a thiamine level of 0.5 over 120 hours.
```

**Response:** 
```
The predicted pyruvic acid concentration is 4.25 mmol/L.
```

**Prompt:** 
```
Calculate the vitisin potential for a pyruvic acid concentration of 5.0 and an anthocyanin profile of {'anthocyaninConcentration': 15.0, 'typeDistribution': 'primary'}.
```

**Response:** 
```
The predicted concentrations are vitisin A: 2.1 and vitisin B: 1.4.
```

**Prompt:** 
```
What is the color stability score if vitisin A is 2.1, vitisin B is 1.4, oxygen exposure is 0.5, and initial anthocyanin is 15.0?
```

**Response:** 
```
The predicted color stability score is 0.78.
```

## Frequently Asked Questions

**How does this tool help with wine color?**
It predicts how pyruvic acid reacts with anthocyanins to form stable vitisin complexes, which are essential for long-term color permanence.

**What is the role of thiamine in these models?**
Thiamine is a critical cofactor. The `evaluate_fermentation_environment` tool can identify if low thiamine levels will cause a metabolic bottleneck in pyruvate production.

**Can I model different yeast strains?**
Yes, you can specify different yeast strains in `get_pyruvic_acid_accumulation` to see how their metabolic coefficients affect acid accumulation.
