# Ring System Analysis

**Discipline**: Organic Chemistry | **Tools Used**: 4 | **Servers**: 3

## Description

Analyze ring systems: count aliphatic carbocycles, analyze aromaticity, compute topology, and structure complexity.

## Tools Used

- **`GetAliphaticCarbocyclesNum`** from `server-31` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/31/SciToolAgent-Chem`
- **`AromaticityAnalyzer`** from `server-28` (sse) - `https://scp.intern-ai.org.cn/api/v1/mcp/28/InternAgent`
- **`calculate_mol_topology`** from `server-2` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool`
- **`calculate_mol_structure_complexity`** from `server-2` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/2/DrugSDA-Tool`

## Workflow

1. Count aliphatic carbocycles
2. Analyze aromaticity
3. Calculate topological descriptors
4. Assess structural complexity

## Test Case

### Input
```json
{
    "smiles": "C1CCC(CC1)c1ccccc1"
}
```

### Expected Steps
1. Count aliphatic carbocycles
2. Analyze aromaticity
3. Calculate topological descriptors
4. Assess structural complexity

## Usage Example

> **Note:** Replace `sk-b04409a1-b32b-4511-9aeb-22980abdc05c` with your own SCP Hub API Key. You can obtain one from the [SCP Platform](https://scphub.intern-ai.org.cn).
