# Antigravity

> Connect ContentHero to Google Antigravity over the hosted OAuth MCP server.

Antigravity connects to remote MCP servers from its MCP configuration.

## Add the server

Open **Settings, Customizations, Open MCP Config** (or edit `~/.gemini/config/mcp_config.json` directly) and add ContentHero:

```json theme={null}
{
  "mcpServers": {
    "contenthero": {
      "serverUrl": "https://mcp.contenthero.ai"
    }
  }
}
```

The field is `serverUrl` for a remote server. Antigravity registers the client automatically, so no client ID or key is needed.

## Authorize

The first call opens the OAuth consent page in your browser. Sign in with your ContentHero account and approve. Antigravity stores and refreshes the token for you.

## Verify

Ask Antigravity to read your ContentHero balance. It calls `get_balance` and returns your credits. The ContentHero tools appear as `mcp__contenthero__*`.
