# Medical Research Toolkit

Query 14+ biomedical databases for drug repurposing, target discovery, clinical evidence, and literature research — all via a unified MCP endpoint.

## ⚡ 30-Second Start

```bash
# Find drugs for myasthenia gravis
curl -X POST https://mcp.cloud.curiloo.com/tools/unified/mcp \
  -H "Content-Type: application/json" -H "Accept: application/json" \
  -d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"chembl_find_drugs_by_indication","arguments":{"indication":"myasthenia gravis","max_results":10}},"id":1}'

## Use Cases

### 🧬 Drug Repurposing
Find non-standard-care drugs for rare/complex diseases:
1. Find disease targets (OpenTargets)
2. Search for drugs targeting those genes (ChEMBL)
3. Check ongoing trials (ClinicalTrials)
4. Verify safety (OpenFDA, PubMed)

### 🔬 Target Discovery
Identify novel therapeutic targets:
1. Find disease associations (OpenTargets, GWAS)
2. Get pathway context (Reactome, KEGG)
3. Review literature (PubMed)
4. Check protein properties (UniProt)

### 📋 Clinical Evidence Review
Compile evidence for a hypothesis:
1. Search trials (ClinicalTrials.gov)
2. Find literature (PubMed)
3. Check FDA data (OpenFDA)

### 📊 Literature Mining
Systematically search biomedical research:
1. PubMed: 35M+ articles searchable by gene, disease, drug, chemical
2. Preprints: bioRxiv, medRxiv
3. Filter by keywords, date, study type

- **Caching**: Automatic 30-day HTTP caching (RFC 9111)
- **Cost**: $0 (all databases public or researcher-accessible)

## Common Patterns

### Batch Query Loop

```bash
# Search multiple targets
for gene in CHRNE RAPSN LRP4; do
  curl -X POST https://mcp.cloud.curiloo.com/tools/unified/mcp \
    -H "Content-Type: application/json" -H "Accept: application/json" \
    -d "{\"jsonrpc\":\"2.0\",\"method\":\"tools/call\",\"params\":{\"name\":\"chembl_find_drugs_by_target\",\"arguments\":{\"target_name\":\"$gene\",\"max_results\":10}},\"id\":1}"
  sleep 1  # Be nice to the API
done
```

### ID Conversion

Need to convert IDs between databases?

```bash
curl -X POST https://mcp.cloud.curiloo.com/tools/unified/mcp \
  -H "Content-Type: application/json" -H "Accept: application/json" \
  -d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"nodenorm_get_normalized_nodes","arguments":{"curie":"HGNC:11998"}},"id":1}'
```

Returns: Equivalent IDs in NCBI Gene, Uniprot, Ensembl, MyGene, etc.

---

## Troubleshooting

**No results?**
- Try alternative terms (gene symbol vs protein name)
- Check spelling
- Use standardized IDs (gene symbols, disease names)
- Some APIs use specific ID formats (EFO vs MONDO, etc.)

**Too many results?**
- Add filters (max_results, phase, recruitment status)
- Use `limit` or `size` parameters
- Combine with other databases to narrow focus

**API key errors?**
- OMIM requires API key — get from https://omim.org/api
- Other databases optional — request key if hitting rate limits

---

## Next Steps

1. **Pick a use case** (drug repurposing, target discovery, etc.)
2. **Read the relevant database guide** from References section
3. **Copy a quick recipe** from above
4. **Customize parameters** for your disease/gene/drug
5. **Scale up** — build your full research workflow
