Connect Antigravity to Agent Authority

Google's agent-first IDE and CLI, built on Gemini. Once connected, Antigravity reaches every tool your organization has approved through a single governed endpoint, with every call authenticated, policy-checked, and audited.

Setup

1. Add the MCP server — Add the following to ~/.gemini/config/mcp_config.json (or .agents/mcp_config.json in your workspace):

{
  "mcpServers": {
    "secureauth": {
      "serverUrl": "https://your-gateway-url/gateway/mcp"
    }
  }
}

Antigravity uses serverUrl for remote servers, not url.

2. Authenticate — Antigravity opens a browser for sign-in the first time it connects. Or type /mcp in the prompt panel to reconnect from the MCP Manager.

3. Start using — Antigravity picks up the tools on the next turn.

The agent is auto-registered on first connect.

Connecting to just one MCP? To stay under an agent's tool limit, point the URL at a single MCP — /gateway/mcp/{slug} instead of /gateway/mcp. Grab the exact URL from the resource's detail page; see Scope a connection to one MCP.

Next steps

• Create a policy — control which tools Antigravity can call.
• Monitor activity — watch its tool calls appear in the dashboard and audit log.
• Audit log — filter and search every tool call Antigravity makes.
