String Database

This connects Claude to the STRING database's 59 million proteins and 20 billion interaction records across 5000+ species. You get six core functions: map gene names to STRING IDs, pull interaction networks with confidence scores, generate network visualizations, discover interaction partners, run GO/KEGG enrichment analysis, and test if protein sets are significantly connected. The confidence thresholds matter here: 400 is standard, 700 is high confidence, 900 is very stringent. It's built for systems biology work where you need to move quickly from a gene list to pathway context or from one protein to its functional neighborhood. The enrichment uses Fisher's exact test with FDR correction, so the statistics are proper.
