tooluniverse

tooluniverse is a skill for Claude Code, Codex from silverstein/claude-scientific-skills-desktop. It costs 112 tokens per session (2,215 once invoked), scanned A, original, MIT.

A common interface for finding and using hundreds of scientific tools, datasets, models, and research databases. It covers areas such as genomics, proteins, chemistry, and drug discovery.

In plain words
What is it for?
Use it to discover tools, query scientific databases, run analyses, and combine several research steps into one workflow.
Why use it?
It reduces the need to learn and connect many separate research services when building computational science workflows.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

tooluniverse scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/example_tool_search.py, scripts/example_workflow.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

ToolUniverse

Overview

ToolUniverse is a unified ecosystem that enables AI agents to function as research scientists by providing standardized access to 600+ scientific resources. Use this skill to discover, execute, and compose scientific tools across multiple research domains including bioinformatics, cheminformatics, genomics, structural biology, proteomics, and drug discovery.

Key Capabilities:

  • Access 600+ scientific tools, models, datasets, and APIs
  • Discover tools using natural language, semantic search, or keywords
  • Execute tools through standardized AI-Tool Interaction Protocol
  • Compose multi-step workflows for complex research problems
  • Integration with Claude Desktop/Code via Model Context Protocol (MCP)

When to Use This Skill

Use this skill when:

  • Searching for scientific tools by function or domain (e.g., "find protein structure prediction tools")
  • Executing computational biology workflows (e.g., disease target identification, drug discovery, genomics analysis)
  • Accessing scientific databases (OpenTargets, PubChem, UniProt, PDB, ChEMBL, KEGG, etc.)
  • Composing multi-step research pipelines (e.g., target discovery → structure prediction → virtual screening)
  • Working with bioinformatics, cheminformatics, or structural biology tasks
  • Analyzing gene expression, protein sequences, molecular structures, or clinical data
  • Performing literature searches, pathway enrichment, or variant annotation
  • Building automated scientific research workflows

Quick Start

Basic Setup

from tooluniverse import ToolUniverse

# Initialize and load tools
tu = ToolUniverse()
tu.load_tools()  # Loads 600+ scientific tools

# Discover tools
tools = tu.run({
    "name": "Tool_Finder_Keyword",
    "arguments": {
        "description": "disease target associations",
        "limit": 10
    }
})

# Execute a tool
result = tu.run({
    "name": "OpenTargets_get_associated_targets_by_disease_efoId",
    "arguments": {"efoId": "EFO_0000537"}  # Hypertension
})

What ships with it

8 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

tooluniverse is a skill published in the GitHub repository silverstein/claude-scientific-skills-desktop (22 stars, last pushed 5mo ago), licensed MIT. It adds 112 tokens to every session and 2,215 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
