## Description

This MCP server provides precise tools for knitters and crocheters to swap yarns safely. Use `get_substitution_requirements` to determine the exact grams and skeins needed when changing yarn weight or gauge. Use `analyze_fiber_compatibility` to check if different materials like wool and cotton will behave similarly in your project. You can also use `get_gauge_impact_summary` to understand how a change in gauge will physically alter the dimensions of your finished piece.

## Tools

### analyze_fiber_compatibility
Analyze fiber compatibility

### get_gauge_impact_summary
Summarize gauge impact

### get_substitution_requirements
Calculate substitute yarn requirements

## Prompt Examples

**Prompt:** 
```
I want to substitute a worsted weight wool yarn (100g, 200m/g) with a bulky acrylic yarn (50g, 100m/g). The pattern needs 500m. The gauge difference is 15%. How much do I need?
```

**Response:** 
```
You will need 575 grams of the bulky acrylic yarn, which equals 12 skeins based on the 50g weight.
```

**Prompt:** 
```
Is it okay to use silk instead of alpaca for this sweater?
```

**Response:** 
```
The compatibility score is 85. While both have good drape, silk has significantly less elasticity than alpaca, which may cause the sweater to stretch out over time.
```

**Prompt:** 
```
How much will my project change if my gauge is 10% thicker than the pattern?
```

**Response:** 
```
A 10% thicker gauge will result in a smaller project if you do not adjust your yardage. You should apply a 1.10 multiplier to your required meters.
```

## Frequently Asked Questions

**How do I know if my substitute yarn is the right amount?**
You can use the `get_substitution_requirements` tool. By providing the original yarn specs and the substitute yarn specs, it calculates the exact grams and skeins required.

**Can I substitute cotton for wool?**
To check this, use `analyze_fiber_compatibility`. It will provide a compatibility score and a warning if the lack of elasticity in cotton might affect your project's drape.

**What happens if my gauge is different?**
The `get_gauge_impact_summary` tool explains how the gauge difference will change the size of your project and provides a multiplier to adjust your yardage.
