Query the statgen-analysis OKG for datasets matching a trait, EFO term, seed-dataset, or curated category, with controlled-vocab ancestry filtering (EUR/AFR/EAS/AMR/SAS/admixed/unknown), minimum-N power threshold, and sumstats-availability filter. Outputs a TSV ready to feed into `gwas-fetch GCST<X>` for batch chaining (e.g. genetic correlation with related immune traits). Auto-installs psycopg on first use and connects via the OKG_DSN env var; no MCP-server roundtrip overhead. Use when a user asks "what other GWAS exist for trait X", "what immune-trait studies are in the graph", "find sibling datasets like this one", or wants to bulk-pull a panel of GCSTs for rg / cross-…
