## 🚀 Installation

### Via Composer

```bash
composer require dalehurley/php-mcp-sdk
```

### Development Version

```bash
composer require dalehurley/php-mcp-sdk:dev-main
```

## ⚡ Quick Start

### Creating an MCP Server

```php
#!/usr/bin/env php
tool(
    'say_hello',
    'Says hello to someone',
    [
        'type' => 'object',
        'properties' => [
            'name' => [
                'type' => 'string',
                'description' => 'Name of the person to greet'
            ]
        ],
        'required' => ['name']
    ],
    function (array $args): array {
        $name = $args['name'] ?? 'World';

        return [
            'content' => [
                [
                    'type' => 'text',
                    'text' => "Hello, {$name}! 👋 Welcome to MCP!"
                ]
            ]
        ];
    }
);

// Start the server
async(function () use ($server) {
    echo "🚀 Hello World MCP Server starting...\n";

    $transport = new StdioServerTransport();
    $server->connect($transport)->await();
})->await();
```

### Creating an MCP Client

```php
#!/usr/bin/env php
 'php',
    'args' => [__DIR__ . '/weather-server.php']
]);

Amp\async(function() use ($client, $transport) {
    try {
        // Connect to server
        yield $client->connect($transport);
        echo "✅ Connected to weather server\n";

        // List available tools
        $result = yield $client->listTools();
        echo "📋 Available tools:\n";
        foreach ($result['tools'] as $tool) {
            echo "  - {$tool['name']}: {$tool['description']}\n";
        }

        // Call the weather tool
        $result = yield $client->callTool('get-weather', [
            'location' => 'London, UK'
        ]);

        echo "\n🌤️  Weather result:\n";
        echo $result['content'][0]['text'] . "\n";

        yield $client->close();

    } catch (\Exception $error) {
        echo "❌ Error: " . $error->getMessage() . "\n";
    } finally {
        Loop::stop();
    }
});

Loop::run();
```

### Test Your Implementation

```bash
# Run the hello-world server
php examples/getting-started/hello-world-server.php

# Test with Claude Desktop by adding to your configuration:
{
  "mcpServers": {
    "hello-world": {
      "command": "php",
      "args": ["/path/to/examples/getting-started/hello-world-server.php"]
    }
  }
}

# Or test with the MCP Inspector (Node.js required)
npx @modelcontextprotocol/inspector examples/getting-started/hello-world-server.php
```

```

```php
// In a Laravel controller or service
use MCP\Server\McpServer;
use MCP\Types\Implementation;

class McpController extends Controller
{
    public function createServer()
    {
        $server = new McpServer(
            new Implementation('my-laravel-app', '1.0.0')
        );

        // Register your tools, resources, and prompts
        $server->tool('search-users', 'Search for users', [
            'type' => 'object',
            'properties' => [
                'query' => ['type' => 'string', 'description' => 'Search query']
            ]
        ], function($params) {
            return [
                'content' => [
                    [
                        'type' => 'text',
                        'text' => json_encode(User::where('name', 'like', "%{$params['query']}%")->get())
                    ]
                ]
            ];
        });

        return $server;
    }
}
