Usage Examples

Search for Drug Information

Ask about a medication's uses, dosage, and safety information:

{
  "tool": "search-drugs",
  "arguments": { "query": "Tylenol", "limit": 5 }
}

Get Health Statistics

Retrieve global health indicators like life expectancy or mortality rates:

{
  "tool": "get-health-statistics",
  "arguments": {
    "indicator": "Life expectancy at birth (years)",
    "country": "USA"
  }
}

Search Medical Literature

Find peer-reviewed research articles on any medical topic:

{
  "tool": "search-medical-literature",
  "arguments": { "query": "COVID-19 treatment", "max_results": 10 }
}

Data Sources

Security & Privacy

• ✅ Localhost-only – Server runs locally, no external access
• ✅ No data storage – All queries are real-time, nothing saved
• ✅ Process isolation – Medical data stays on your machine
• ✅ No API keys – No credentials to manage or leak

Use Cases

• Medical Researchers – Quick literature reviews without paywalls
• Healthcare Developers – Build prototypes with real medical data
• Students – Access drug information and research papers
• Clinicians – Reference tool for drug details and health statistics
• Pediatricians – AAP guidelines, Bright Futures, pediatric literature, and child health data

Caching

The server includes an in-memory caching layer to improve response times and reduce API calls:

• Automatic Caching: All API responses are cached with source-specific TTL policies
• TTL Policies:
  • FDA data: 24 hours
  • PubMed articles: 1 hour
  • WHO statistics: 7 days
  • RxNorm nomenclature: 30 days
  • Clinical guidelines: 7 days
  • Google Scholar: 1 hour
  • Bright Futures: 30 days
  • AAP Policy: 7 days
  • Pediatric journals: 1 hour
  • Child health indicators: 7 days
  • Pediatric drugs: 24 hours
• Cache Management: Automatic cleanup of expired entries every 5 minutes
• LRU Eviction: Least recently used entries are evicted when cache exceeds 1000 entries
• Cache Statistics: Use `get-cache-stats` tool to view hit rates and memory usage

Configuration (via environment variables):

• `CACHE_ENABLED=true` - Enable/disable caching (default: true)
• `CACHE_MAX_SIZE=1000` - Maximum cache entries (default: 1000)
• `CACHE_TTL_FDA=86400` - FDA TTL in seconds (default: 86400)
• `CACHE_TTL_PUBMED=3600` - PubMed TTL in seconds (default: 3600)
• `CACHE_TTL_WHO=604800` - WHO TTL in seconds (default: 604800)
• `CACHE_TTL_RXNORM=2592000` - RxNorm TTL in seconds (default: 2592000)
• `CACHE_CLEANUP_INTERVAL=300000` - Cleanup interval in milliseconds (default: 300000)

Performance: Cached responses typically return in <10ms vs 800-1500ms for API calls. Expected cache hit rate: 60%+ for common queries.
