  "function": {
    "name": "get_weather",
    "description": "Get current weather for a location",

      "properties": {
        "location": { "type": "string", "description": "City name" }
      },
      "required": ["location"]
    }
  },
  "server": {
    "url": "https://your-server.com/weather"
  }
}

Supported tool types: function, apiRequest, transferCall, endCall, dtmf, handoff
