One-step install on Google Antigravity (AGY / Antigravity IDE / Antigravity 2.0): an MCP server exposing 1000+ scientific tools plus 120+ research skills — all auto-configured.
Prerequisites (check once)
uv --version # provides `uvx`; if missing: curl -LsSf https://astral.sh/uv/install.sh | sh
agy --version # Antigravity CLI; if missing: https://antigravity.google
Install
In Antigravity, plugins can be installed using the agy CLI:
Option 1: Direct path / imported plugin install (recommended)
# If installed via Claude Code / Codex marketplace cache or cloned repo:
agy plugin install /path/to/ToolUniverse/plugin
Option 2: Clone + install
git clone https://github.com/mims-harvard/ToolUniverse.git
cd ToolUniverse
agy plugin install ./plugin
Restart Antigravity. The MCP server auto-starts via uvx tooluniverse on first use (~30 s cold start while the package downloads, instant after).

Expect output showing tooluniverse under imports:
{
"imports": [
{
"name": "tooluniverse",
"source": "claude-code",
"components": [
"skills",
"agents",
"mcpServers",
"hooks",
"commands"
]
}
]
}
Inside Antigravity, just ask naturally:
What are the top mutated genes in breast cancer?
Research the drug metformin.
The research skills auto-activate on matching questions, and the MCP tools are discovered and run via find_tools → execute_tool — no command prefix needed.
What you get
| Component | What it does | How it's used |
|---|---|---|
| MCP server | 1000+ tools via find_tools, get_tool_info, execute_tool |
Auto-loaded; no action needed |
| 120+ skills | Structured research workflows (drug discovery, variant interpretation, pharmacovigilance, phylogenetics, statistical modeling, etc.) | Auto-activate on matching questions |
| Research agent | Autonomous multi-database research subagent | Auto-routed on complex research tasks |
API keys (optional, but recommended)
Most tools work without keys. For higher rate limits or gated databases, set the keys you care about in ~/.gemini/config/plugins/tooluniverse/mcp_config.json or pass them in environment variables:
export NCBI_API_KEY="your_key"
export ONCOKB_API_TOKEN="your_token"
export SEMANTIC_SCHOLAR_API_KEY="your_key"
Update
uv cache clean tooluniverse
Restart Antigravity.
Troubleshooting
| Symptom | Fix |
|---|---|
uvx: command not found |
Install uv (see Prerequisites), reopen terminal. |
| MCP server won't start | Run uv cache clean tooluniverse or uvx --refresh tooluniverse --help in terminal. |
| Plugin installs but tools missing | Restart Antigravity CLI/IDE. First launch downloads the package (~30 s). |
requires-python >= 3.10 |
