Antigravity (agy)

Antigravity (also referred to as agy or agy-cli) is Google's AI coding agent. This repo ships a purpose-built plugin for it.

Install the plugin globally

The plugins/gca-admin/ directory is a ready-to-install Antigravity plugin. Installing it globally makes the MCP server and skills available across all your workspaces.

agy plugin install https://github.com/pauldatta/gemini-code-assist-admin-mcp/tree/main/plugins/gca-admin

Or from a local clone:

agy plugin install ./plugins/gca-admin

The plugin registers:

  • MCP server — all 16 admin tools become available to the agent
  • Skills — the agent gains knowledge of GCA administration workflows

Workspace-level skill (auto-discovery)

When you open this repo directory in Antigravity, the workspace skill in .agents/skills/gca-admin.md is automatically discovered. No installation needed — just open the repo and the /gca-admin skill is available.

cd /path/to/gemini-code-assist-admin-mcp
agy  # skill is auto-loaded

plugin.json reference

The plugin is defined in plugins/gca-admin/plugin.json:

{
  "$schema": "https://antigravity.google/schemas/v1/plugin.json",
  "name": "gca-admin",
  "version": "1.0.0",
  "description": "Administrative tools for Gemini Code Assist license management and analytics",
  "author": "Paul Datta"
}

MCP config used by the plugin

plugins/gca-admin/mcp_config.json points to the built MCP server:

{
  "mcpServers": {
    "gemini-code-assist-admin": {
      "command": "npx",
      "args": ["-y", "gemini-code-assist-admin-mcp"]
    }
  }
}

Example prompts

Once the plugin is installed, talk to your agent naturally:

  • "Who has GCA licenses in my organisation? Pull the full list."
  • "Enable the GCA API in project staging-env-9821 and verify it's working."
  • "Create a code repository index for my GitHub org and set up two groups — backend and frontend."
  • "Show me which developers actually used Gemini Code Assist last month."

The agent will orchestrate multiple tool calls automatically.
