# Connect Google Antigravity

Wire **[Google Antigravity](https://antigravity.google)** to Chartbuddy Hub over local stdio MCP.

## Setup via Chartbuddy Hub

1. Install Chartbuddy Hub and launch it once (approve OS security prompts).
2. Open **AI connections** in Hub (title-bar cable icon).

3) Connect **Antigravity**. Hub writes the server into your global Antigravity MCP config.

4. Restart Antigravity or start a new conversation so tools load.

## Setup manually

Open **Manage MCP Servers → View raw config**, or edit the global MCP file directly:

* macOS / Linux: `~/.gemini/config/mcp_config.json`
* Windows: `%USERPROFILE%\.gemini\config\mcp_config.json`

Add a `Chartbuddy-Hub` entry under `mcpServers` (leave other servers untouched):

::: code-group

```json [Windows]
{
  "mcpServers": {
    "Chartbuddy-Hub": {
      "command": "C:\\Users\\YOUR_USER\\AppData\\Local\\Programs\\Chartbuddy\\chartbuddy.exe",
      "args": ["--mcp"]
    }
  }
}
```

```json [macOS]
{
  "mcpServers": {
    "Chartbuddy-Hub": {
      "command": "/Applications/Chartbuddy.app/Contents/MacOS/chartbuddy",
      "args": ["--mcp"]
    }
  }
}
```

:::

Keep **Chartbuddy Hub** running. Restart Antigravity or start a new conversation so tools load.

If Antigravity reports that the command cannot be found, confirm Chartbuddy is installed at the path above (or use Hub's AI connections button to rewrite the entry).

## Verify

::: code-group

```powershell [Windows]
& "$env:LOCALAPPDATA\Programs\Chartbuddy\chartbuddy.exe" --mcp-status
```

```bash [macOS]
/Applications/Chartbuddy.app/Contents/MacOS/chartbuddy --mcp-status
```

:::

Exit `0` = Chartbuddy Hub bridge up.
