# Antigravity

> Connect the UseAgents MCP server to Antigravity IDE and the Gemini CLI.

Connect UseAgents to Antigravity so your AI assistant can discover verified developer tools from the registry. Antigravity offers two products that support MCP — the Antigravity IDE and the Gemini CLI.

<Note>
  UseAgents is **currently free** during our public beta. No API key is required. Requests are subject to [rate limits](/api-reference/rate-limit).
</Note>

## Antigravity IDE

### Option 1: MCP Store

1. Open the side panel in Antigravity IDE.
2. Click the **"…" (three dots)** dropdown at the top of the panel.
3. Select **MCP Store**.
4. Search for **UseAgents** and click **Install**.

### Option 2: Manual config

If UseAgents is not listed in the MCP Store, add it manually:

1. Open the **"…"** dropdown → **MCP Store** → **Manage MCP Servers**.
2. Click **View raw config** to open the `mcp_config.json` file.
3. Add the UseAgents server:

```json theme={null}
{
  "mcpServers": {
    "UseAgents": {
      "url": "https://mcp.useagents.site/mcp"
    }
  }
}
```

4. Save the file. The IDE will automatically detect the changes.

### Verify

1. Ensure you are in **Agent Mode** (toggle in the chat interface).
2. Ask the agent to search for a tool — for example: *"Use UseAgents to find a TypeScript SDK for Stripe."*
3. Confirm you receive structured tool results.

## Gemini CLI

### Option 1: CLI command

Run this in your terminal:

```bash theme={null}
gemini mcp add UseAgents --url https://mcp.useagents.site/mcp
```

### Option 2: Settings file

Edit the settings file to add UseAgents manually.

| Scope             | Path                                   |
| ----------------- | -------------------------------------- |
| **User (global)** | `~/.gemini/settings.json`              |
| **Project**       | `<project-root>/.gemini/settings.json` |

Add the UseAgents MCP server configuration to the file:

```json theme={null}
{
  "mcpServers": {
    "UseAgents": {
      "url": "https://mcp.useagents.site/mcp"
    }
  }
}
```

### Verify

1. Start a Gemini CLI session.
2. Type `/mcp` to list all active MCP servers and confirm `UseAgents` appears.
3. Ask the agent to search for a tool using `search_tools`.

## Troubleshooting

* **Server not detected in IDE**: Save the config file and wait a moment — the IDE auto-detects changes without a restart.
* **Agent not using tools**: Make sure you are in Agent Mode, not the standard chat mode.
* **CLI add command fails**: Try editing the settings file manually instead.
