# Test server health
curl http://localhost:8000/health

# Test via MCP
python -c "from src.ncbi_mcp_server.server import cache_stats; import asyncio; print(asyncio.run(cache_stats()))"

Configuration

NCBI API Key (Optional but Recommended)

For higher rate limits and better performance:

Register at NCBI: https://www.ncbi.nlm.nih.gov/account/
Get API key: https://www.ncbi.nlm.nih.gov/account/settings/
Add to server code in src/ncbi_mcp_server/server.py:

# Replace the line: ncbi_client = NCBIClient()
# With:
ncbi_client = NCBIClient(
    email="your.email@university.edu",
    api_key="your_api_key_here"
)

Rate Limits

Without API key: 3 requests/second
With API key: 10 requests/second
With API key + email: Higher limits for bulk requests
