# Creating Your First Dynamic Tool
This guide will walk you through the process of creating and registering your first dynamic tool.
### 1. Set Up Your Project
Make sure you have followed any [Getting Started Guides](/getting_started/manual_installation) and have the MCP server and a Flutter app running.
### 2. Create the Tool
In your Flutter app, create a new file called `lib/my_tools.dart` and add the following code:
```dart
import 'package:mcp_toolkit/mcp_toolkit.dart';
void registerMyTools() {
final helloTool = MCPCallEntry.tool(
handler: (params) {
return MCPCallResult(message: 'Hello from a dynamic tool!');
},
definition: MCPToolDefinition(
name: 'hello',
description: 'A simple tool that says hello.',
),
);
addMcpTool(helloTool);
}
```
### 3. Register the Tool
In your `lib/main.dart` file, import `my_tools.dart` and call `registerMyTools()` in your `main` function:
```dart
import 'package:flutter/material.dart';
import 'package:mcp_toolkit/mcp_toolkit.dart';
import 'my_tools.dart';
void main() {
WidgetsFlutterBinding.ensureInitialized();
MCPToolkitBinding.instance.initialize();
registerMyTools();
runApp(const MyApp());
}
```
### 4. Hot Reload and Use the Tool
Save your changes and hot reload the app. Now, you can ask your AI assistant to run the `hello` tool. It should respond with "Hello from a dynamic tool!".
