Install in Antigravity

Add Levirge Search to Google Antigravity (IDE and CLI) with one block in mcp_config.json, then Authenticate in Agent Settings.

Antigravity's IDE, CLI and SDK share one MCP config, so set it up once and every surface picks it up.

1 · Open the raw config

In the IDE, click … at the top of the agent side panel and choose MCP Servers, then Manage MCP Servers → View raw config. (In the CLI, type /mcp.)

2 · Add the server

In ~/.gemini/config/mcp_config.json:

{
  "mcpServers": {
    "search": {
      "serverUrl": "https://search.levirge.com/mcp"
    }
  }
}

The field must be serverUrl — Antigravity ignores url. Put the same block in .agents/mcp_config.json to enable it for one workspace only.

3 · Sign in

Open Agent Settings (⌘, / Ctrl+,), go to the Customizations tab and click Authenticate next to search. Sign in in the browser, copy the code it shows, paste it back into Antigravity and click Submit.

Then ask it a research question, or verify with a read-only call — stealth_list returns the stealth-domain registry.

Prefer a token? Add "headers": { "Authorization": "Bearer <your-token>" } instead of authenticating; mint one on Profile → Your tokens.
