## Description

This MCP server provides specialized tools for assessing Safety Instrumented Functions (SIF) against IEC 61508 and IEC 61511 standards. It allows engineers to calculate the Probability of Failure on Demand (PFDavg) and Risk Reduction Factor (RRF) using `evaluate_sif_performance`. You can verify if your hardware architecture meets specific safety targets with `verify_architectural_compliance`, or predict how changing maintenance schedules affects safety using `simulate_test_impact`. The tool also includes `validate_failure_data` to ensure your reliability datasets are mathematically sound before performing critical safety calculations.

## Tools

### evaluate_sif_performance
Calculates the primary reliability metrics for a single SIF configuration

### simulate_test_impact
Predicts how changing the proof test frequency will affect the SIL achievement

### validate_failure_data
Ensures that the provided failure rate data is mathematically consistent and logically sound

### verify_architectural_compliance
Checks if the hardware configuration is sufficient for the target SIL

## Prompt Examples

**Prompt:** 
```
Calculate the reliability metrics for a SIF with a 720-hour test interval.
```

**Response:** 
```
The calculated PFDavg is 0.0012, providing a Risk Reduction Factor (RRF) of 833, which meets SIL 2 requirements.
```

**Prompt:** 
```
Will increasing the test interval from 8760 to 17520 hours affect my SIL rating?
```

**Response:** 
```
Increasing the interval to 17520 hours will increase the PFDavg to 0.0045, which would result in a drop from SIL 2 to SIL 1.
```

**Prompt:** 
```
Is a 1oo1 Type A architecture compliant for SIL 3?
```

**Response:** 
```
No, a 1oo1 Type A architecture is not compliant for SIL 3 due to insufficient hardware fault tolerance requirements.
```

## Frequently Asked Questions

**How do I calculate the PFDavg for my safety loop?**
You can use the `evaluate_sif_performance` tool by providing your SIF configuration and the intended test interval in hours.

**Can I check if my hardware meets SIL 2 requirements?**
Yes, use `verify_architectural_compliance` to check if your hardware type and redundancy level satisfy the target SIL requirements.

**What happens if my failure rate data is invalid?**
The `validate_failure_data` tool will identify inconsistencies, such as negative failure rates or invalid diagnostic coverage, before you proceed with calculations.
