ToolUniverse: Democratizing AI scientists [//]: (mcp name: io.github.mims harvard/tooluniverse) Install AI agent (recommended) — open your AI agent and run: [安装/使用命令见下方] The agent will walk you through MCP configuration, API keys, skill installation, and validation. or set up manually Add to your MCP config file: [安装/使用命令见下方] refresh checks PyPI for the newest release on every launch. Drop it ( "args": ["tooluniverse"] ) to start faster from uv 's cache — then upgrade with uv cache clean tooluniverse . Install agent skills: [安装/使用命令见下方] Claude Code users — one line, no config file: [安装/使用命令见下方] Python developers — install the SDK. Install uv first and do not use system pip : on a current Mac, pip install tooluniverse fails with externally managed environment (PEP 668) and python3 m venv can fail at ensurepip . uv manages its own Python and avoids both. [安装/使用命令见下方] The base install covers the API and database tools. Local ML, cheminformatics, and plotting tools need extras — uv pip install 'tooluniverse[all]' , or a single group such as [ml] , [visualization] , [bioinformatics] . Note [all] excludes singlecell , smolagents , client , and build , which install by name. Run tooluniverse doctor to see which groups are missing. tu CLI — discover, inspect, run, and test tools from the terminal. Python SDK — programmatic access for building AI scientist systems.

ToolUniverse is an ecosystem for creating AI scientist systems from any large language model. Powered by the AI Tool Interaction Protocol, it standardizes how LLMs identify and call tools, integrating more than 1000 machine learning models, datasets, APIs, and scientific packages for data analysis, knowledge retrieval, and experimental design. Key features: AI Tool Interaction Protocol : Standardized interface governing how AI scientists issue tool requests and receive results Universal AI Model Support : Wo
