String Database

If you're doing bioinformatics or protein research, this lets Claude query the STRING database directly through a Python CLI wrapper. STRING is a well-known resource for protein-protein interaction networks, so this is genuinely useful for anyone working with molecular biology data who wants to pull interaction data programmatically. It's part of Google DeepMind's science-skills collection, which explains the academic focus. One thing to note: it requires uv to be installed and makes you acknowledge STRING's terms of use on first run, which is the right way to handle external database access but means it's not quite plug and play. Over 950 installs suggests the scientific computing crowd has found it.
