## INSTALL ToolUniverse

<table>
<tr>
<td width="45%" valign="top">

**1️⃣ MCP Setup** – Add to your MCP config:
```json
{
  "mcpServers": {
    "tooluniverse": {
      "command": "uvx",
      "args": ["tooluniverse"],
      "env": {"PYTHONIOENCODING": "utf-8"}
    }
  }
}
```

</td>
<td width="45%" valign="top">

**2️⃣ Install Agent Skills**
```bash
npx skills add mims-harvard/ToolUniverse
```

**3️⃣ Install Package** (Optional)
```bash
uv pip install tooluniverse
```

</td>
</tr>
</table>

> **Guided Setup:** Install skills first with `npx skills add mims-harvard/ToolUniverse`, then ask your AI coding agent **"setup tooluniverse"**. The `setup-tooluniverse` skill will walk you through MCP configuration, API keys, and validation step by step.

## 🔬 What is ToolUniverse?

ToolUniverse is an ecosystem for creating AI scientist systems from any open or closed large language model (LLM). Powered by 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.

AI scientists are emerging computational systems that serve as collaborative partners in discovery. However, these systems remain difficult to build because they are bespoke, tied to rigid workflows, and lack shared environments that unify tools, data, and analysts into a common ecosystem.

ToolUniverse addresses this challenge by providing a standardized ecosystem that transforms any AI model into a powerful research scientist. By abstracting capabilities behind a unified interface, ToolUniverse wraps around any AI model (LLM, AI agent, or large reasoning model) and enables users to create and refine entirely custom AI scientists without additional training or finetuning.

**Key Features:**

- [**Compact Mode**](https://zitniklab.hms.harvard.edu/ToolUniverse/guide/building_ai_scientists/compact_mode.html): Reduces 1000+ tools to 4-5 core discovery tools, saving ~99% context window while maintaining full capability
- [**Two-Tier Result Caching**](https://zitniklab.hms.harvard.edu/ToolUniverse/guide/cache_system.html): In-memory LRU + SQLite persistence with per-tool fingerprinting for 10x speedup, offline support, and reproducibility
- [**Literature Search Across 11+ Databases**](https://zitniklab.hms.harvard.edu/ToolUniverse/guide/literature_search_tools_tutorial.html): Unified search across PubMed, Semantic Scholar, ArXiv, BioRxiv, Europe PMC, and more with AI-powered query expansion
- [**Human Expert Feedback**](https://zitniklab.hms.harvard.edu/ToolUniverse/guide/expert_feedback.html): Human-in-the-loop consultation where AI agents can escalate to domain experts in real-time via a web dashboard
- [**Scientific Visualization**](https://zitniklab.hms.harvard.edu/ToolUniverse/guide/visualization_tutorial.html): Interactive 3D protein structures and 2D/3D molecule visualizations rendered as HTML
- [**Make Your Data Agent-Searchable**](https://zitniklab.hms.harvard.edu/ToolUniverse/guide/make_your_data_agent_searchable.html): Turn any text or JSON data into an agent-searchable collection with one CLI command, shareable on HuggingFace
