# Drug Target Identification Pipeline

**Discipline**: Drug Discovery | **Tools Used**: 3 | **Servers**: 3

## Description

Identify drug targets for a disease by querying OpenTargets for associated targets, then retrieve detailed target info from ChEMBL and protein data from UniProt.

## Tools Used

- **`get_associated_targets_by_disease_efoId`** from `opentargets-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/15/Origene-OpenTargets`
- **`get_target_by_name`** from `chembl-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/4/Origene-ChEMBL`
- **`get_general_info_by_protein_or_gene_name`** from `uniprot-server` (streamable-http) - `https://scp.intern-ai.org.cn/api/v1/mcp/10/Origene-UniProt`

## Workflow

1. Query OpenTargets for lung cancer targets
2. Get EGFR target details from ChEMBL
3. Get EGFR protein info from UniProt

## Test Case

### Input
```json
{
    "disease_efo_id": "EFO_0000311",
    "disease_name": "lung cancer"
}
```

### Expected Steps
1. Query OpenTargets for lung cancer targets
2. Get EGFR target details from ChEMBL
3. Get EGFR protein info from UniProt

## 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).
