### Description (declared)

# uniprot-mcp

[![CI](https://github.com/fzlzjerry/uniprot-mcp/actions/workflows/ci.yml/badge.svg)](https://github.com/fzlzjerry/uniprot-mcp/actions/workflows/ci.yml)

> GitHub repo: `fzlzjerry/uniprot-mcp` · PyPI package & command: **`uniprotkb-mcp`**
> (the Python import package is `uniprot_mcp`).

A production-quality **MCP server** that exposes the [UniProt REST API](https://rest.uniprot.org)
to LLM clients (Claude Code, Claude Desktop, …) over **stdio**. Built with
[FastMCP](https://gofastmcp.com) and managed with [`uv`](https://docs.astral.sh/uv/).

Tools return **compact, token-efficient summaries by default** and full payloads
only on request, with robust error handling and an embedded UniProt query
cheat-sheet so the model writes valid queries.

## Tools

| Tool | What it does |
|------|--------------|
| `search_uniprotkb` | Search UniProtKB with native query syntax. `reviewed` / `organism_id` filters are added for you. Summary, FASTA, or TSV output. |
| `get_entry` | One entry as a curated digest (function, names, organism, length, subcellular location, family/domains, key features, PTMs, keywords, PDB/AlphaFold/Ensembl/RefSeq/InterPro/GO cross-refs) or `json`/`fasta`/`txt`/`gff`. |
| `get_fasta` | Raw FASTA for one accession or a batch. |
| `map_ids` | Convert ids across databases via UniProt's async ID-mapping (e.g. `RefSeq_Protein`→`UniProtKB`, `UniProtKB_AC-ID`→`PDB`). Returns mapped pairs **and** unmapped ids; validates the db pair against the live config. |
| `get_taxonomy` | Resolve an organism name or taxon id → taxon id, names, rank, lineage. Turn "human" into `organism_id:9606`. |
| `search_uniref` | Search UniRef100/90/50 sequence-similarity clusters. |
| `search_proteomes` | Search proteomes (whole-organism protein sets); reference-proteome filter. |

Plus an MCP **resource** `resource://uniprot/query-cheatsheet` documenting the
UniProtKB query syntax (`gene:`, `organism_id:`, `reviewed:true`,
`length:[X TO Y]`, `keyword:`, `ec:`, boolean `AND…
