Search scientific papers and retrieve structured experimental evidence extracted from full-text studies via the BGPT MCP server (`search_papers`, plus `lookup_paper` by DOI), returning 25+ fields per paper (methods, results, sample sizes, quality scores, limitations, conclusions). Use when running a literature review or evidence synthesis, or when needing experimental details (sample sizes, effect sizes, methods, quality scores) that abstracts alone do not provide. Part of the AlterLab Academic Skills suite.
