# Google Antigravity

> Use Darwin from Google Antigravity 2.0, CLI, or IDE over remote MCP.

Add Darwin once at the user level or keep the configuration local to one workspace.

```json theme={null}
{
  "mcpServers": {
    "darwin": {
      "serverUrl": "https://mcp.darwin.so/mcp"
    }
  }
}
```

Antigravity can begin OAuth automatically for compatible remote servers, so the configuration contains no Darwin credential. Complete authorization through the client instead of adding a token to the JSON file.

Open **Settings → Customizations → Installed MCP Servers** or run `/mcp` in the CLI. Save the same object in `.agents/mcp_config.json` for one workspace. Reload, complete OAuth, and keep Action mutations in **Ask** mode.

```text theme={null}
Search Darwin for a harmless capability. Show the exact capability ID and
revision, and stop before starting an Action.
```

<Warning>
  Antigravity's MCP permission setting controls whether the client may call a tool. It does not replace Darwin approval,
  payment, authentication, or verification interactions.
</Warning>

Google documents custom installation but no public third-party MCP Store submission path. [Open the checked configuration](https://github.com/darwin-studios/darwin-integrations/blob/main/configs/antigravity-mcp.json) or Google's [MCP guide](https://antigravity.google/docs/mcp/).
