setup-tooluniverse

description

Install and configure ToolUniverse for any use case — MCP server (chat-based), CLI (command line with 9 subcommands), or Python SDK (Coding API with 3 calling patterns). Covers uv/uvx setup, MCP configuration for 12+ AI clients (Cursor, Claude Desktop, Windsurf, VS Code, Codex, Gemini CLI, Trae, Cline, etc.), full CLI reference (tu list/grep/find/info/run/test/status/build/serve), Coding API quickstart, agentic tools, code executor, API key walkthrough, skill installation, and upgrading. Use when user asks how to set up ToolUniverse, which access mode to use (MCP vs CLI vs SDK), configuring MCP servers, using the CLI, troubleshooting installation, upgrading, or mentions installing ToolUniverse or setting up scientific tools. Also triggers for "how do I use ToolUniverse", "what's the best way to access tools", "command line", "tu command", "coding API", "tu build".

Setup ToolUniverse

Guide the user step-by-step through setting up ToolUniverse.

Agent Behavior

• Detect language from user's first message. Respond in their language; keep commands/URLs in English.
• Go one step at a time. Ask before proceeding.
• Use AskQuestion for structured choices.
• Explain briefly in plain language. Celebrate small wins.
• When something goes wrong, help troubleshoot before moving on.

Internal Notes (do not show)

ToolUniverse has 1200+ tools. The tooluniverse command enables compact mode automatically, exposing only 5 core MCP tools (list_tools, grep_tools, get_tool_info, execute_tool, find_tools) while keeping all tools accessible via execute_tool.

What is ToolUniverse?

Always explain first, in plain language:

ToolUniverse is free, open-source software connecting to 2,000+ scientific databases (PubMed, UniProt, ChEMBL, FAERS, ClinicalTrials.gov, etc.). Instead of visiting each website, you search from one place. Think of it like a universal remote for scientific databases.

Why AI assistants? The AI reads your question, figures out which databases to search, runs queries, and summarizes results. You just ask your question.

Step 1: Choose How to Use It

Present using AskQuestion:

Mode	What it means	Who it's for
Chat mode	Ask questions to an AI assistant. No coding.	Most researchers.
Command line	Type short commands in Terminal.	Quick tests. Terminal-comfortable users.
Python code	Write scripts for automated pipelines.	Programmers.

Options: "I want to ask questions" → Chat mode | "Quick try" → CLI | "I write Python" → SDK | "I don't know" → Recommend Chat mode

If Chat mode, ask which app (AskQuestion): Cursor, Claude Desktop, VS Code/Copilot, Windsurf, Claude Code, Gemini CLI, Codex, Cline/Trae/Antigravity/OpenCode. "I don't have any" → Recommend Claude Desktop.

Step 2: Install uv

Only prerequisite: uv (manages everything else automatically).

Terminal help (if needed): Mac: Cmd+Space → "Terminal" → Enter. Windows: Win key → "PowerShell" → Enter.

curl -LsSf https://astral.sh/uv/install.sh | sh

(This is a safe, standard command that downloads and installs uv, a small package manager. It's widely used by Python developers. Close and reopen your terminal after it finishes.)

Verify: uv --version

CLI Setup

Make sure Step 2 is done, then try:

uvx --from tooluniverse tu status              # How many tools?
uvx --from tooluniverse tu find 'drug safety'  # Search by topic
uvx --from tooluniverse tu info FAERS_count_death_related_by_drug  # See params
uvx --from tooluniverse tu run FAERS_count_death_related_by_drug '{"drug_name": "metformin"}'

First run takes ~30s (downloads package), then instant. Shortcut: uv tool install tooluniverse → then just use tu directly.

All CLI subcommands

Command	What it does	Example
tu status	Show tool count and top categories	tu status
tu list	List tools (modes: names, categories, basic, by_category, summary, custom)	tu list --mode basic --limit 20
tu find	Search by natural language (keyword scoring, no API key needed)	tu find 'protein structure analysis'
tu grep	Text/regex pattern search	tu grep '^UniProt' --mode regex
tu info	Show tool parameters and schema	tu info PubMed_search_articles
tu run	Execute a tool	tu run PubMed_search_articles '{"query": "CRISPR"}'
tu test	Test a tool with its example inputs	tu test UniProt_get_entry_by_accession
tu build	Generate typed Python wrappers for Coding API	tu build --output ./my_tools
tu serve	Start MCP stdio server (same as uvx tooluniverse)	tu serve

Output flags (most commands except build/serve): --json (pretty) or --raw (compact, pipe-friendly).

Continue to Step 3 (API Keys).

SDK Setup

Make sure Step 2 is done. For detailed patterns, invoke the tooluniverse-sdk skill.

uv pip install tooluniverse

Coding API — 3 calling patterns

Pattern 1: Direct import (typed, with autocomplete):

from tooluniverse.tools import UniProt_get_entry_by_accession
result = UniProt_get_entry_by_accession(accession="P12345")

Pattern 2: Attribute access (no import needed per tool):

from tooluniverse import ToolUniverse
tu = ToolUniverse()
tu.load_tools()
result = tu.tools.UniProt_get_entry_by_accession(accession="P12345")

Pattern 3: JSON-based (dynamic, for pipelines):

result = tu.run({"name": "UniProt_get_entry_by_accession", "arguments": {"accession": "P12345"}})

Generate typed wrappers: tu build (creates importable Python modules with autocomplete).

Agentic Tools & Code Executor

ToolUniverse also includes 23 AI-powered agentic tools (ScientificTextSummarizer, HypothesisGenerator, ExperimentalDesignScorer, peer-review tools, etc.) and 2 code executor tools (python_code_executor, python_script_runner). These are called like any other tool — via tu.run() or execute_tool(). Agentic tools require an LLM API key (e.g., OPENAI_API_KEY).

Continue to Step 3 (API Keys).

MCP Setup (Chat Mode)

Make sure Step 2 is done (uv --version works).

Add ToolUniverse to your app's config

Config file help (if user seems unfamiliar): Config files are plain text that store settings — like a preference list for the app. You don't need to understand the format; just paste exactly what's shown below. Most apps have a Settings button that opens the file for you (see table). If the file is empty, paste the entire block. If it already has content, the agent should help merge it.

Default config (same for most clients):

{
  "mcpServers": {
    "tooluniverse": {
      "command": "uvx",
      "args": ["tooluniverse"],
      "env": { "PYTHONIOENCODING": "utf-8" }
    }
  }
}

Config file locations:

Claude Code users: skip manual MCP config — use the plugin instead. Invoke the tooluniverse-claude-code-plugin skill or run:

claude plugin marketplace add mims-harvard/ToolUniverse
claude plugin install tooluniverse@tooluniverse

This installs MCP server + 115 skills + slash commands in one step.

Client	File	How to Access
Cursor	~/.cursor/mcp.json	Settings → MCP → Add new global MCP server
Claude Desktop	~/Library/Application Support/Claude/claude_desktop_config.json	Settings → Developer → Edit Config
Claude Code	~/.claude.json or .mcp.json	claude mcp add or edit directly (or use plugin — see above)
Windsurf	~/.codeium/windsurf/mcp_config.json	MCP hammer icon → Configure
Cline	cline_mcp_settings.json	Cline panel → MCP Servers → Configure
Gemini CLI	~/.gemini/settings.json	gemini mcp add or edit directly
Trae	.trae/mcp.json	Ctrl+U → AI Management → MCP → Configure

Different formats: VS Code uses "servers" key with "type": "stdio". Codex uses TOML. OpenCode uses "mcp" key. See references/mcp-configs.md for these.

Continue to Step 3 (API Keys).

Step 3: API Keys

Many tools work without keys, but some unlock powerful features. Ask research interests first (AskQuestion):

• Literature / Drug discovery / Protein structure / Genomics / Rare diseases / Enzymology / Patent search / AI analysis / All / Skip

Map to recommended keys (2-4 to start). Walk through one at a time: explain what it unlocks, give registration link, wait for key, add to config.

Tier 1 (Core — recommend for most users):

Key	Unlocks	Free?	Registration
NCBI_API_KEY	PubMed (rate limit 3→10/s)	Yes	https://account.ncbi.nlm.nih.gov/settings/
NVIDIA_API_KEY	16 tools: AlphaFold2, docking, genomics	Yes	https://build.nvidia.com
BIOGRID_API_KEY	Protein interaction queries	Yes	https://webservice.thebiogrid.org/
FDA_API_KEY	FDA adverse events, drug labels (rate 240→1000/min)	Yes	https://open.fda.gov/apis/authentication/

Tier 2 (Specialized — based on interests):

Key	Unlocks	Registration
DISGENET_API_KEY	Gene-disease associations	https://disgenet.com/academic-apply
OMIM_API_KEY	Mendelian/rare disease	https://omim.org/api
ONCOKB_API_TOKEN	Precision oncology	https://www.oncokb.org/apiAccess
UMLS_API_KEY	Medical terminology	https://uts.nlm.nih.gov/uts/

See API_KEYS_REFERENCE.md for the complete list with all tiers.

Adding keys:

Chat mode — add to env block in MCP config:

"env": {
  "PYTHONIOENCODING": "utf-8",
  "NCBI_API_KEY": "your_key_here"
}

CLI — set environment variables:

export NCBI_API_KEY="your_key_here"       # Current session
echo 'export NCBI_API_KEY="key"' >> ~/.zshrc  # Persist across sessions

SDK — same as CLI (export or .env file).

Step 4: Test Together

Don't just tell — do it WITH the user.

Chat mode: Ask user to restart app. Then run a test call yourself:

1. list_tools or grep_tools with "PubMed" — confirm tools visible
2. execute_tool("PubMed_search_articles", {"query": "CRISPR", "max_results": 1}) — confirm it works
3. Celebrate: "It works! You have access to 1200+ scientific tools."

CLI: Run together:

tu status && tu find 'protein' && tu run PubMed_search_articles '{"query": "CRISPR", "max_results": 1}'

SDK: Run the Python snippet from SDK Setup together.

If issues: Most common: app not restarted, uv not in PATH (reopen terminal), JSON syntax error in config.

Step 5: Install Skills (Recommended for Chat Mode)

Skills are pre-built research workflows that turn basic tool calls into expert investigations.

Chat mode users: The agent should run this for the user:

git clone --depth 1 https://github.com/mims-harvard/ToolUniverse.git /tmp/tu-skills

Then copy to client's skill directory:

Client	Command
Cursor	mkdir -p .cursor/skills && cp -r /tmp/tu-skills/skills/* .cursor/skills/
Claude Code	mkdir -p .claude/skills && cp -r /tmp/tu-skills/skills/* .claude/skills/
Windsurf	mkdir -p .windsurf/skills && cp -r /tmp/tu-skills/skills/* .windsurf/skills/
Codex	mkdir -p .agents/skills && cp -r /tmp/tu-skills/skills/* .agents/skills/
Gemini CLI	mkdir -p .gemini/skills && cp -r /tmp/tu-skills/skills/* .gemini/skills/

Clean up: rm -rf /tmp/tu-skills

Skills activate automatically based on user's question. Try: "Research the drug metformin" or "What does the literature say about CRISPR in cancer?"

CLI users: Skills are designed for AI chat agents. Use tu find, tu info, tu run instead. For full multi-step workflows, use Chat mode or build SDK pipelines.

What's Next? (Guided First Use)

Don't list suggestions — run a live demo WITH the user.

Pick a demo query based on research interests (from Step 3):

Interest	First query	Skill
Literature	"What does the literature say about CRISPR in cancer?"	literature-deep-research
Drug discovery	"Research the drug metformin"	drug-research
Protein structure	"Find protein structures for human EGFR"	protein-structure-retrieval
Genomics	"What genes are associated with type 2 diabetes?"	disease-research
Rare diseases	"Patient with progressive ataxia and oculomotor apraxia — differential diagnosis?"	rare-disease-diagnosis
Drug safety	"What are the adverse events for pembrolizumab?"	pharmacovigilance
General	"Research the drug aspirin"	drug-research

Run the demo — invoke the skill and show real results.

Prompt cheat sheet (share after demo)

Chat mode users:

1. "Research the drug [name]" — full drug profile
2. "Research [disease]" — comprehensive disease analysis
3. "What are the known targets of [drug]?" — target intelligence
4. "What does the literature say about [topic]?" — deep literature review
5. "Find protein structures for [protein]" — 3D structures
6. "Is [variant] pathogenic?" — variant interpretation
7. "What drugs could be repurposed for [disease]?" — repurposing
8. "What are the adverse events for [drug]?" — safety analysis
9. "Find clinical trials for [disease/drug]" — trial matching
10. "What are the protein interactions for [gene]?" — interaction network
11. "What are the clinical guidelines for [condition]?" — practice guidelines
12. "Check drug interactions between [drug1] and [drug2]" — DDI analysis

Just ask naturally — I'll figure out which databases to search.

CLI users:

tu find 'drug safety'           # Discover tools
tu info PubMed_search_articles  # Check parameters
tu run PubMed_search_articles '{"query": "CRISPR cancer", "max_results": 3}'
tu run UniProt_get_entry_by_accession '{"accession": "P12345"}'
tu run FAERS_count_death_related_by_drug '{"drug_name": "metformin"}'

Write Agent Memory

After setup, write a reminder to the agent's memory file so future sessions know ToolUniverse is available.

Client	File
Cursor	.cursor/rules/tooluniverse.md
Claude Code	CLAUDE.md or .claude/CLAUDE.md (append)
Windsurf	.windsurf/rules/tooluniverse.md
VS Code/Copilot	.github/copilot-instructions.md (append)
Codex / OpenCode	AGENTS.md (append)
Gemini CLI	GEMINI.md (append)
Cline	.clinerules/tooluniverse.md
Trae	.trae/rules/tooluniverse.md

Content:

# ToolUniverse
For any scientific research question (drugs, genes, proteins, diseases, literature, clinical trials, etc.), invoke the `tooluniverse` skill — it routes to specialized research skills and 1,200+ database tools.

Append (don't overwrite). Check for existing section first. Ask user permission.

Team / Project-Level Setup

If setting up ToolUniverse for a team or shared project:

Shared API keys: Create a .env file at the project root with all keys. Most clients and the CLI/SDK will pick up keys from .env automatically:

NCBI_API_KEY=your_shared_key
NVIDIA_API_KEY=your_shared_key

Project-level MCP config (so all team members get ToolUniverse automatically):

• Cursor: .cursor/mcp.json in project root
• Claude Code: .mcp.json in project root
• VS Code: .vscode/mcp.json in project root
• Windsurf: project-level via Windsurf UI

Project-level skills: Install skills into the project (e.g., .cursor/skills/) so all team members share them.

Team-wide upgrade: Each team member runs uv cache clean tooluniverse and restarts their app. To pin a specific version, use "args": ["tooluniverse==X.Y.Z"] in the MCP config.
