## Quick Start

### npx (Recommended)

```json
{
  "mcpServers": {
    "pexbot": {
      "command": "npx",
      "args": ["-y", "@pexbot/mcp"],
      "env": {
        "PEXBOT_API_KEY": "pxb_your_api_key_here"
      }
    }
  }
}
```

> No API key yet? Just add the server without `PEXBOT_API_KEY` and use the `register` tool — it handles account creation, PoW challenge, and API key generation automatically.
