Use Cases

🧬 Drug Repurposing

Find non-standard-care drugs for rare/complex diseases:

Find disease targets (OpenTargets)
Search for drugs targeting those genes (ChEMBL)
Check ongoing trials (ClinicalTrials)
Verify safety (OpenFDA, PubMed)

🔬 Target Discovery

Identify novel therapeutic targets:

Find disease associations (OpenTargets, GWAS)
Get pathway context (Reactome, KEGG)
Review literature (PubMed)
Check protein properties (UniProt)

📋 Clinical Evidence Review

Compile evidence for a hypothesis:

Search trials (ClinicalTrials.gov)
Find literature (PubMed)
Check FDA data (OpenFDA)

📊 Literature Mining

Systematically search biomedical research:

PubMed: 35M+ articles searchable by gene, disease, drug, chemical
Preprints: bioRxiv, medRxiv
Filter by keywords, date, study type

API Endpoint

Common Patterns

Batch Query Loop

# 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?

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
