v1.0.2 — Google Antigravity MCP Server

First public release of mcp-server-google-antigravity — a small MCP server that lets Claude (or any MCP client) hand its heavy work to Google Antigravity's agy agent (Gemini under the hood). Fire a task, get a jobId instantly, and poll for the result while your primary model keeps working.

Install

Claude Desktop (claude_desktop_config.json):

{
  "mcpServers": {
    "antigravity": {
      "command": "npx",
      "args": ["-y", "mcp-server-google-antigravity"],
      "env": { "AGY_MODEL": "Gemini 3.5 Flash (Medium)", "AGY_AUTO_APPROVE": "true" },
      "timeout": 900000
    }
  }
}

Windows: Electron can't always spawn npx directly — use "command": "cmd" with "args": ["/c", "npx", "-y", "mcp-server-google-antigravity"].

Requires the agy CLI (curl -fsSL https://antigravity.google/cli/install.sh | bash, or the PowerShell equivalent on Windows). See the README for full setup.

Highlights

• 14 tools — async delegation (use_antigravity), long-polling results, filesystem helpers, model/agent listing, and an antigravity_health diagnostic
• Async & unlimited jobs — no request ever blocks; jobs run in the background and stream live progress notifications
• Cross-platform — macOS, Windows, Linux (with a node-pty fast path + automatic fallback on Windows)
• Listed on the official MCP Registry as io.github.TurkerYakup/mcp-server-google-antigravity
