Run `search_ncbi_sequences` to pull UIDs for specific genomic queries. This avoids manual database browsing and keeps your research focused. Your AI client processes the results instantly, allowing you to narrow down your sequence candidates before you start any heavy analysis.

Fetch sequence summaries via MCP Server

Use `get_ncbi_summary` to retrieve metadata for any sequence ID you identify. You get the raw facts without parsing complex XML manually. This MCP Server handles the data extraction, delivering clean summaries directly into your chat window so you can audit the findings immediately.

Check connectivity status

Verify your link to the NCBI E-utilities service using `check_api_status`. It is the fastest way to confirm your environment is ready to query. If you encounter delays, this tool identifies whether the issue is local or an upstream API outage, saving you from guessing where the connection failed.
