  "arguments": { "query": "Tylenol", "limit": 5 }
}

Get Health Statistics

Retrieve global health indicators like life expectancy or mortality rates:

{
  "tool": "get-health-statistics",

    "indicator": "Life expectancy at birth (years)",
    "country": "USA"
  }
}

Search Medical Literature

Find peer-reviewed research articles on any medical topic:

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.

Technical Details

Built with: Node.js, TypeScript, MCP SDK
