## Description

This MCP server provides tools to calculate Growing Degree Units (GDU), a critical metric for predicting crop phenology. By processing temperature data, it allows AI agents to track thermal accumulation from planting through maturity. Use `calculate_daily_gdu` to compute daily heat units, `get_cumulative_gdu` to sum heat over time, `predict_growth_stage` to identify current V-stages or R-stages, and `predict_maturity_and_harvest` to estimate physiological maturity dates and harvest windows.

## Tools

### calculate_daily_gdu
Calculates the GDU value for a single day based on different mathematical methods

### get_cumulative_gdu
Calculates the total heat accumulated from the planting date up to a specific target date

### predict_growth_stage
Identifies which growth stage (V-stage or R-stage) the crop is likely in based on cumulative heat

### predict_maturity_and_harvest
Estimates the date when the crop will reach maturity and the subsequent harvest window

## Prompt Examples

**Prompt:** 
```
Calculate the GDU for a day with a max temp of 30°C, min temp of 15°C, base temp of 10°C, upper threshold of 35°C using the standard method.
```

**Response:** 
```
The calculated GDU for that day is 12.5.
```

**Prompt:** 
```
What growth stage is a corn crop in if it has accumulated 800 GDUs?
```

**Response:** 
```
Based on the provided thresholds, the corn is currently in the V12 stage.
```

**Prompt:** 
```
Estimate the maturity date for a crop planted on May 1st that requires 1200 GDUs to mature, given a forecast of steady temperatures.
```

**Response:** 
```
The crop is estimated to reach maturity on July 15th, with a harvest window starting July 18th.
```

## Frequently Asked Questions

**What is a Growing Degree Unit (GDU)?**
A GDU is a measure of heat accumulation used to predict how quickly a crop will develop through its various growth stages.

**How can I predict my harvest date?**
You can use the `predict_maturity_and_harvest` tool by providing the planting date, the required GDU for maturity, and a temperature forecast.

**Does this tool account for environmental stress?**
Yes, the `calculate_daily_gdu` tool accepts a `stressFactor` to adjust heat accumulation for conditions like drought or waterlogging.
