ToolUniverse

ToolUniverse (Zitnik Lab, Harvard Medical School; arXiv:2509.23426) is a large biomedical/scientific tool ecosystem shipped as a Claude Code plugin -- confirmed by direct fetch, its .claude-plugin/marketplace.json wraps a single tooluniverse plugin sourced from ./plugin, whose own .claude-plugin/plugin.json (also fetched directly) is embedded verbatim below -- and separately documented for Gemini CLI via a first-party mcpServers configuration recipe wiring the tooluniverse-smcp-stdio MCP server into ~/.gemini/settings.json (https://zitniklab.hms.harvard.edu/bioagent/guide/building_ai_scientists/gemini_cli.html (opens in a new tab), fetched directly). Its own plugin.json names concrete genomics/health-research data sources -- TCGA, GWAS Catalog, NHANES, ClinicalTrials.gov, PubMed, UniProt, PubChem -- a real, nameable relevance fact, not vague health branding. Marginal fit, flagged explicitly: ToolUniverse's actual scope (1000+ tools, 120+ skills) spans biology, chemistry, medicine, and general data science, of which genomics/health-research is a real but partial slice rather than the project's sole focus; this entry does not claim, and does not attempt, to enumerate ToolUniverse's full tool catalogue. Terms check: the repository's root LICENSE file (fetched directly) is the Apache License, Version 2.0, matching the license field in both plugin.json and the README. No slug collision against any existing entry in this registry.
