About Hgnc

Hgnc is an MCP server for querying the HGNC catalog of approved human genes. It supports exact symbol lookup, fuzzy search, and mapping external database identifiers to full gene records.

Key features

  1. 01Exact lookup by approved HGNC symbol
  2. 02Fuzzy search across symbols, names, and aliases
  3. 03Resolve external database IDs
  4. 04Full gene records with cross-references

Use cases

  1. 01Find a gene from a symbol fragment or name
  2. 02Retrieve an approved human gene record
  3. 03Map an Entrez or Ensembl ID to an HGNC gene

MCP support

Exposes gene lookup, search, and cross-reference resolution as MCP tools. It can run as a local stdio server or connect through the Pipeworx gateway.

Configuration

Remote servers need no local install. Pick your client, then copy the config or install in one click.

Details

From the project README

mcp-hgnc

HGNC (HUGO Gene Nomenclature Committee) MCP.

Part of Pipeworx — an MCP gateway connecting AI agents to 1881+ live data sources. This is an independent, unofficial integration — not affiliated with, endorsed by, or published by the upstream provider.

Tools

ToolDescription
get_geneExact lookup of an approved human gene by its official HGNC symbol — returns the full authoritative record: approved name, locus type, chromosomal location, alias/previous symbols, gene groups, and cross-references (Entrez, Ensembl, UniProt, OMIM, RefSeq, UCSC, CCDS). Use search_genes first if you only have a name fragment or aren't sure of the exact symbol. Keyless.
search_genesFuzzy search across approved symbols, names, and aliases — e.g. "breast cancer", "p53", "tumor protein". Returns lightweight matches (hgnc_id, symbol, relevance score) ranked by score; call get_gene with a returned symbol for the full record. Keyless.
resolve_xrefReverse-lookup: map an external database id to its canonical HGNC gene. "What gene is Entrez 672?" -> BRCA1. Accepts entrez_id, ensembl_gene_id, uniprot_ids, omim_id, refseq_accession, or ucsc_id and returns the same full record as get_gene. Keyless.

Quick Start

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

{
  "mcpServers": {
    "hgnc": {
      "url": "https://gateway.pipeworx.io/hgnc/mcp"
    }
  }
}
What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/hgnc/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

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

Both URLs reach the same gateway and the same 1881+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

No MCP client? Call it over HTTP

curl -X POST https://gateway.pipeworx.io/v1/tools/hgnc_get_gene \
  -H 'Content-Type: application/json' \
  -d '{"symbol":"BRCA1"}'

No account needed for the first calls. Inspect any tool: GET https://gateway.pipeworx.io/v1/tools/hgnc_get_gene. Find one: POST https://gateway.pipeworx.io/v1/tools/search_packs with {"query":"..."}.

Standalone (no gateway account)

This package also runs as a local stdio MCP server — no Pipeworx account, no gateway round-trip:

{
  "mcpServers": {
    "hgnc": {
      "command": "npx",
      "args": ["-y", "@pipeworx/mcp-hgnc"]
    }
  }
}

Or run it directly to confirm it starts:

npx -y @pipeworx/mcp-hgnc

It speaks MCP over stdin/stdout and answers initialize/tools/list/tools/call for only this pack's tools — none of the shared meta-tools the gateway connection above adds. Same source, same tools, no ask_pipeworx routing.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Hgnc data" })

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

New to MCP?

From what the protocol is to installing your first server, these answers cover most first questions.

An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
