## Description

This MCP server provides structural engineering tools to evaluate reinforcement density in concrete sections. It allows AI agents to verify if rebar spacing is sufficient for aggregate passage, ensure mechanical vibrators can access the cage, and calculate a congestion score to prevent honeycombing. Use `calculate_clear_spacing` to find physical gaps, `check_aggregate_passage` to verify aggregate flow, `evaluate_vibration_access` for tool clearance, and `get_congestion_score` for a density assessment.

## Tools

### evaluate_vibration_access
Checks if there is enough room for a concrete vibration tool to enter the cage

### calculate_clear_spacing
Determines the actual physical gap between rebar elements

### check_aggregate_passage
Verifies if the specified concrete aggregate can pass through the rebar cage

### get_congestion_score
Provides a high-level assessment of the reinforcement density

## Prompt Examples

**Prompt:** 
```
Check if 20mm aggregate can pass through a cage with 16mm bars in a 300x300mm section with 40mm cover and 2 layers.
```

**Response:** 
```
The aggregate can pass through the reinforcement cage.
```

**Prompt:** 
```
What is the congestion score for 25mm bars in a 500x500mm section with 50mm cover and 3 layers?
```

**Response:** 
```
The congestion score is 15, which is considered Low risk.
```

**Prompt:** 
```
Will a 40mm vibrator needle fit in a section with 12mm bars and 30mm clear cover?
```

**Response:** 
```
No, the vibrator needle cannot access the target areas.
```

## Frequently Asked Questions

**How do I check if my aggregate will fit between the bars?**
You can use the `check_aggregate_passage` tool by providing the bar sizes, section dimensions, and the maximum aggregate diameter.

**Can this tool help prevent concrete honeycombing?**
Yes, by using `get_congestion_score` and `evaluate_vibration_access`, you can identify if the reinforcement is too crowded for proper concrete consolidation.

**What information is needed for the spacing calculation?**
To use `calculate_clear_spacing`, you need the array of bar diameters, the number of layers, the section width and height, and the clear cover.
