# Metabolomics Pathway Analysis

**Discipline**: Metabolomics | **Tools Used**: 4 | **Servers**: 2

## Description

Analyze metabolomics: compound identification, KEGG pathway mapping, enzyme links, and PubChem data.

## Tools Used

- **`search_pubchem_by_name`** from `pubchem-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/8/Origene-PubChem`
- **`kegg_find`** from `kegg-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/5/Origene-KEGG`
- **`kegg_link`** from `kegg-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/5/Origene-KEGG`
- **`kegg_get`** from `kegg-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/5/Origene-KEGG`

## Workflow

1. Identify compound in PubChem
2. Find in KEGG
3. Link to enzymes
4. Get pathway details

## Test Case

### Input
```json
{
    "metabolite": "glucose",
    "pathway": "hsa00010"
}
```

### Expected Steps
1. Identify compound in PubChem
2. Find in KEGG
3. Link to enzymes
4. Get pathway details

## 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).
