## Description

This MCP server provides essential tools for Statistical Process Control (SPC). It allows AI agents to calculate control limits, identify center lines, and detect out-of-control patterns in manufacturing or service processes. Using tools like `calculate_control_parameters` and `analyze_process_stability`, agents can determine if a process is stable or if it exhibits non-random trends and shifts.

## Tools

### generate_individual_limits
Specifically calculates limits for processes where measurements are taken one at a time (Individual charts)

### analyze_process_stability
Determines if a process is in a state of statistical control based on provided measurements and chart type

### calculate_control_parameters
Generates the mathematical boundaries for a specific SPC chart type

### detect_out_of_control_patterns
Identifies specific non-random patterns in a sequence of data points

## Prompt Examples

**Prompt:** 
```
Calculate the control limits for these subgroups: [[10, 12], [11, 13], [9, 11]] using an x_bar chart.
```

**Response:** 
```
The calculated parameters for the x_bar chart are: UCL: 13.5, LCL: 8.5, and Center Line: 11.0.
```

**Prompt:** 
```
Is this process stable? Measurements: [10, 10, 10, 15, 10], chartType: 'individual', controlLimits: {"ucl": 12, "lcl": 8}, centerLine: 10
```

**Response:** 
```
The process is unstable. A violation was detected because the measurement 15 falls outside the upper control limit of 12.
```

**Prompt:** 
```
Find patterns in this series: [10, 11, 12, 13, 14, 15], centerLine: 10, ucl: 20, lcl: 0
```

**Response:** 
```
A trend pattern was detected in the series.
```

## Frequently Asked Questions

**What types of charts can I design?**
You can design X-bar, R, S, and Individual (I) charts using the `calculate_control_parameters` and `generate_individual_limits` tools.

**How do I check if my process is stable?**
Use the `analyze_process_stability` tool with your measurements and control limits to detect violations and stability status.

**Can I detect trends in my data?**
Yes, the `detect_out_of_control_patterns` tool is specifically designed to identify trends, shifts, and oscillations in your data series.
