About tooluniverse-antigravity-plugin

A Google Antigravity plugin that adds ToolUniverse’s scientific research skills, agent, and MCP server for users conducting biomedical and scientific research. It installs through the Antigravity CLI and configures these components for use in the IDE.

Key features

  1. 011000+ scientific tools
  2. 02120+ research skills
  3. 03Autonomous research subagent
  4. 04Automatic skill activation
  5. 05CLI-based plugin installation

Use cases

  1. 01Exploring genes implicated in a disease
  2. 02Researching a drug across databases

MCP support

The plugin starts a ToolUniverse MCP server in Antigravity. Clients can discover tools with `find_tools`, inspect them with `get_tool_info`, and run them with `execute_tool`.

Install

Copy the command and run it in a terminal.

Details

From the project README

Install the ToolUniverse Plugin for Google Antigravity (AGY)

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).

agy plugin list

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

ComponentWhat it doesHow it's used
MCP server1000+ tools via find_tools, get_tool_info, execute_toolAuto-loaded; no action needed
120+ skillsStructured research workflows (drug discovery, variant interpretation, pharmacovigilance, phylogenetics, statistical modeling, etc.)Auto-activate on matching questions
Research agentAutonomous multi-database research subagentAuto-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

SymptomFix
uvx: command not foundInstall uv (see Prerequisites), reopen terminal.
MCP server won't startRun uv cache clean tooluniverse or uvx --refresh tooluniverse --help in terminal.
Plugin installs but tools missingRestart Antigravity CLI/IDE. First launch downloads the package (~30 s).
