# 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) ```bash 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) ```bash # If installed via Claude Code / Codex marketplace cache or cloned repo: agy plugin install /path/to/ToolUniverse/plugin ``` ### Option 2: Clone + install ```bash 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). ## Verify it worked ```bash agy plugin list ``` Expect output showing `tooluniverse` under `imports`: ```json { "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: ```bash export NCBI_API_KEY="your_key" export ONCOKB_API_TOKEN="your_token" export SEMANTIC_SCHOLAR_API_KEY="your_key" ``` ## Update ```bash 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` | `uv python install 3.12` | Still stuck: https://github.com/mims-harvard/ToolUniverse/issues
