ToolUniverse: Democratizing AI scientists
Install
AI agent (recommended) — open your AI agent and run:
Read https://aiscientist.tools/setup.md and set up ToolUniverse for me.
The agent will walk you through MCP configuration, API keys, skill installation, and validation.
or set up manually
Add to your MCP config file:
{
"mcpServers": {
"tooluniverse": {
"command": "uvx",
"args": ["--refresh", "tooluniverse"],
"env": {"PYTHONIOENCODING": "utf-8"}
}
}
}
Install agent skills:
npx skills add mims-harvard/ToolUniverse
Python developers — install the SDK:
uv pip install tooluniverse
tu CLI — discover, inspect, run, and test tools from the terminal.
Python SDK — programmatic access for building AI scientist systems.

What is ToolUniverse?
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: Works with Claude, GPT, Gemini, Qwen, Deepseek, and open models
- MCP Integration: Native Model Context Protocol server with configurable transport and tool selection
- Async Operations: Long-running tasks (protein docking, molecular simulations) with progress tracking and parallel execution
- Tool Composition: Chain tools for sequential or parallel execution in self-directed workflows
- Compact Mode: Reduces 1000+ tools to 4-5 core discovery tools, saving ~99% context window
- CLI (
tu): Discover, inspect, run, and test tools directly from the terminal — 9 subcommands for interactive and scripted workflows - Agent Skills: 68 pre-built research workflows for drug discovery, precision oncology, rare disease diagnosis, pharmacovigilance, and more
- Literature Search: Unified search across PubMed, Semantic Scholar, ArXiv, BioRxiv, Europe PMC, and more
- Two-Tier Result Caching: In-memory LRU + SQLite persistence with per-tool fingerprinting for 10x speedup, offline support, and reproducibility
- Continuous Expansion: Register new tools locally or remotely without additional configuration
