This walks you through installing ToolUniverse, the open-source gateway to 2,000+ scientific databases like PubMed, UniProt, and ChEMBL. You get three access patterns: MCP server for chat-based queries in Claude Desktop or Cursor, a CLI with nine subcommands (tu find, tu run, tu test), or a Python SDK with typed imports and JSON-based calls. The guide is explicitly step-by-step and language-aware, covering uv setup, config file locations for a dozen AI clients, API key setup, and the difference between the 1,200+ tools in compact mode versus direct execution. Use this when someone asks how to install ToolUniverse, which mode to pick, or needs MCP troubleshooting for scientific tooling.
