Connects Claude to CDS VizieR, the astronomical catalogue server hosting tens of thousands of datasets. You get four main operations: search catalogue metadata, query specific catalogues by ID, run cone searches around celestial coordinates, and look up objects by name with SIMBAD/NED resolution. Reach for this when you need programmatic access to astronomical survey data, whether you're cross-referencing Gaia positions, pulling photometry from 2MASS, or querying any of the other major catalogues astronomers use daily. Hosted via Pipeworx gateway with streamable HTTP transport, so no local setup required.
