### Answer To activate and configure tools functions from your server when using Vapi, you will need to set up a "function" type tool within your Vapi assistant’s configuration. Here's a basic outline on how to do this: 1. **Define the Tool Configuration**: Specify the type of tool, the server where the function is hosted, and other details such as whether the function call should be synchronous or asynchronous.

{
  "type": "function",
  "messages": [
    {
      "type": "request-start",
      "content": "Processing your request..."
    },
    {
      "type": "request-complete",
      "content": "Function executed successfully!"
    }
  ],
  "function": {
    "name": "your_function_name",
    "parameters": {},
    "description": "A brief description of what the function does"
  },
  "async": false,
  "server": {
    "url": "https://your-server.com/your-function-endpoint"
  }
}

For a more detailed setup and examples, you may refer to the Tools Calling section in the Vapi documentation [Tools Calling]() [(1)]() , [(2)]() .
