## Description

Stop guessing how much yarn you need for your next project. This connector helps knitters and crocheters calculate the exact amount of material required by analyzing key variables like gauge, specific pattern multiples, and overall dimensions. You simply feed in the details—the weight category, the size, and the stitch count—and it handles the complex mathematics. Need to break down a huge garment into separate color sections? Use this MCP's summary tools to aggregate multiple segments into one total report. It supports every yarn weight, from delicate lace to heavy super bulky materials. Because Vinkius hosts over 4,000 specialized connectors, you can connect your preferred AI client and get this utility alongside hundreds of other industry-specific tools, all in one place.

## Tools

### calculate_multi_color_project_summary
Aggregates the yarn requirements needed across multiple color segments into a single total report.

### calculate_single_segment_usage
Calculates the specific amount of yarn required for one individual piece or section.

### get_yarn_weight_catalog
Provides a comprehensive list and data points for different yarn weight categories, useful for accurate constant lookups.

## Prompt Examples

**Prompt:** 
```
I need total yarn for a throw blanket. It's 150x200cm and uses four different colors: red (30x40), blue (30x40), green (30x40), and yellow (30x40).
```

**Response:** 
```
Here is the total project breakdown based on your dimensions and sport weight yarn:

| Segment Color | Size (cm) | Usage Estimate |
| :---: | :---: | :---: |
| Red | 30 x 40 | 25.1 meters |
| Blue | 30 x 40 | 25.1 meters |
| Green | 30 x 40 | 25.1 meters |
| Yellow | 30 x 40 | 25.1 meters |

**Total Project Requirement: 100.4 meters.**
```

**Prompt:** 
```
What yarn weight constants do I need for lace, fingering, and worsted yarn?
```

**Response:** 
```
**Yarn Weight Consumption Constants:**

*   **Lace:** 0.05 yardage per stitch constant.
*   **Fingering:** 0.06 yardage per stitch constant.
*   **Worsted:** 0.12 yardage per stitch constant.

These constants ensure your calculations are based on current industry standards for accurate planning.
```

**Prompt:** 
```
I'm doing a garment with a main body (sport weight) and matching cuffs (lace weight). What do I need?
```

**Response:** 
```
**Calculation Summary:**

*   **Body Segment Estimate:** 68.2 meters of sport weight yarn.
*   **Cuff Segment Estimate:** 14.5 meters of lace weight yarn.

**Total Estimated Yarn: 82.7 meters.** Remember to always check the full catalog for updated constants.

## Capabilities

### Calculate usage for a single color segment
Determines the precise yarn length needed when working on one distinct piece or section.

### Summarize multiple-color projects
Aggregates yarn requirements across several different colored segments to provide a total project yardage estimate.

### Reference the full yarn weight catalog
Retrieves constant data for various yarn weights, allowing you to use accurate conversion factors in your calculations.

## Use Cases

### A multi-color baby blanket project
A crafter needs to know the total yarn for a 4-section blanket using blue (10x10cm) and white (15x15cm) segments. They use `calculate_multi_color_project_summary` to get one consolidated number, confirming they have enough material before starting.

### Estimating a single sleeve pattern
A designer needs the yarn for just one patterned sleeve that is worsted weight. They use `calculate_single_segment_usage` and input the gauge, receiving an immediate metric of required length.

### Checking material viability
A user wants to know what weights are available for their project plan. They call `get_yarn_weight_catalog` first to check constants like lace or super bulky before running any calculations.

### Comparing yarn weight needs
They need to estimate two different parts of a garment: one in sport weight and another in worsted weight. They run separate single segment usage checks for each material type to compare consumption rates accurately.

## Benefits

- Know exactly how much yarn you need. By using `calculate_single_segment_usage`, you get the precise length needed for any individual patch or piece, eliminating guesswork.
- Handle complex designs easily. The ability to aggregate multiple color segments via `calculate_multi_color_project_summary` means one total number for a huge garment project.
- Use reliable constants. You can access the full yarn weight data set using `get_yarn_weight_catalog`, ensuring your calculations use industry-standard metrics.
- Stop wasting money on overstocking. Precise estimates mean you only buy what's needed, saving cash and minimizing waste.
- Supports every material type. Whether it’s fingering weight or super bulky yarn, the MCP handles all major yarn categories accurately.

## How It Works

The bottom line is that you get an accurate, calculated measurement of yarn needed, eliminating manual math and guesswork entirely.

1. Specify the project details: provide the dimensions (e.g., 20cm x 20cm), the gauge measurements, and the yarn weight category.
2. Run the calculation using the appropriate tool—either for a single segment or for summarizing multiple color sections.
3. Receive an immediate report detailing the exact required yardage in meters or yards.

## Frequently Asked Questions

**How do I use the Yarn Length Calculator MCP when my project has many color changes?**
You must use the multi-color summary feature. This tool takes all your individual segment dimensions and gauges, then adds up the total required yarn in a single report. It eliminates manual addition errors.

**Is this MCP good for figuring out if I have enough yarn for one small piece?**
Yes, it’s perfect for that. Use the function designed for individual segments; you input the size and gauge of just that part to get a precise length estimate.

**Can the Yarn Length Calculator handle different yarn weights like lace and super bulky?**
Absolutely. The MCP supports all major fiber categories, from delicate lace up through super bulky materials, ensuring your constants are accurate regardless of the weight you use.

**What information do I need to provide for the Yarn Length Calculator MCP?**
You need three things: the dimensions (length and width), the gauge (stitches/rows per measurement), and the yarn weight category. The more detail you give, the better the calculation.

**Does this MCP just calculate meters or does it support yards too?**
It handles both metric and imperial units for your calculations. You can specify whether you need the final measurement reported in meters or yards to suit your preference.
