UniProt MCP

Connects Claude to UniProtKB, the protein knowledge database maintained by the UniProt consortium. You get read-only access to protein entries, amino acid sequences, functional features, Gene Ontology annotations, taxonomic classifications, and ID mapping between different database identifiers. Reach for this when you're building bioinformatics workflows that need to cross-reference protein data, validate sequences against the canonical database, or pull structured annotations without writing your own UniProt REST client. The MCP wrapper handles the API calls and returns structured data Claude can work with directly for tasks like literature analysis, sequence comparison, or building organism-specific protein datasets.
