SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Setting up the ToolUniverse plugin on Google Antigravity involves easy-to-mistake details like the agy CLI name, the agy plugin install <path> flow, the uvx-based MCP server, and API-key environment variables. This Skill provides the exact, verified steps so you avoid misconfiguration and failed MCP server startups.

Core Features & Use Cases

  • Guided Installation: Walks through prerequisites (uv, agy CLI) and two install paths — direct plugin path install or clone-then-install from the GitHub repository.
  • Verification & Troubleshooting: Shows how to confirm the install with agy plugin list, and provides fixes for common failures like uvx: command not found, MCP server startup errors, and Python version requirements.
  • Lifecycle Management: Covers updating via uv cache clean tooluniverse, configuring optional API keys (NCBI, OncoKB, Semantic Scholar), and understanding what components get installed (MCP server, 120+ skills, research agent).
  • Use Case: You installed the plugin but the scientific tools are not appearing in Antigravity — consult this Skill to diagnose whether it is a uvx cache issue, a missing restart, or a first-launch download delay.

Quick Start

Ask the agent to install and verify the ToolUniverse plugin on Google Antigravity using the agy CLI.

Frequently Asked Questions about tooluniverse-antigravity-plugin

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I install the ToolUniverse plugin on Google Antigravity?▼

Install the ToolUniverse plugin on Antigravity by running `agy plugin install /path/to/ToolUniverse/plugin` after cloning the GitHub repository, then restart Antigravity. The MCP server auto-starts via `uvx tooluniverse` on first use.

How to verify the Antigravity plugin installed correctly?▼

Run `agy plugin list` and check that `tooluniverse` appears under imports with components including skills, agents, mcpServers, hooks, and commands. Then ask a research question inside Antigravity to confirm the tools respond.

Why does the ToolUniverse MCP server fail to start in Antigravity?▼

MCP server startup failures usually come from a missing uv installation or a stale package cache. Run `uv cache clean tooluniverse` or `uvx --refresh tooluniverse --help` in a terminal, and ensure `uv --version` works.

Does the Antigravity plugin require API keys to work?▼

Most ToolUniverse tools work without API keys. Keys like NCBI_API_KEY, ONCOKB_API_TOKEN, and SEMANTIC_SCHOLAR_API_KEY are optional and only needed for higher rate limits or gated databases.

How do I update the ToolUniverse plugin in Antigravity?▼

Update the plugin by running `uv cache clean tooluniverse` and then restarting Antigravity. This forces uvx to fetch the newest release of the tooluniverse package from PyPI.

Can I use this skill for the Claude Code or Codex plugin?▼

No, this skill only covers the Google Antigravity plugin. For Claude Code use the tooluniverse-claude-code-plugin skill, and for Codex use the tooluniverse-codex-plugin skill, since their install flows differ.
