Antigravity

Google Antigravity is the agentic development suite that replaced the standalone Gemini CLI — the terminal tool is now the Antigravity CLI, alongside the Antigravity IDE. Both share one MCP config, so setup is the same either way.

Antigravity uses the serverUrl key for remote MCP servers (not url), in ~/.gemini/config/mcp_config.json:

{
  "mcpServers": {
    "whoworked": {
      "serverUrl": "https://mcp.whoworked.com/mcp"
    }
  }
}

Antigravity IDE

1. Open the ⋯ menu → MCP Servers → Manage MCP Servers.
2. Choose View raw config (or edit ~/.gemini/config/mcp_config.json) and add the entry above.
3. Save, then Refresh the MCP server list.
4. Complete the OAuth sign-in the first time you use a WhoWorked tool.

Antigravity CLI

1. Edit ~/.gemini/config/mcp_config.json (shared with the IDE) and add the entry above.
2. Restart Antigravity, then run /mcp to confirm the connection.

No API keys are needed — Antigravity opens a browser window for the WhoWorked OAuth sign-in on first use.
