mcp-ncbi-eutils

NCBI E-utilities — federated Entrez search/fetch (PubMed/Gene/Nucleotide/…)

Part of Pipeworx — an MCP gateway connecting AI agents to 250+ live data sources.

Tools

Tool	Description
`einfo`	Database info / field list.
`esearch`	Search a database → uid list.
`esummary`	Summary records by uid.
`efetch`	Full records. Returns text (XML/GenBank/FASTA/…) per rettype.
`elink`	Links across databases.
`egquery`	Global query across all Entrez databases.

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "ncbi-eutils": {
      "url": "https://gateway.pipeworx.io/ncbi-eutils/mcp"
    }
  }
}

Or connect to the full Pipeworx gateway for access to all 250+ data sources:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Instead of calling tools directly, you can ask questions in plain English:

ask_pipeworx({ question: "your question about Ncbi Eutils data" })

The gateway picks the right tool and fills the arguments automatically.
