## Setup

## Setup

To install the SDK, run:

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

For Symfony integration, the SDK provides server integration points tailored to Symfony Console and HttpFoundation (Laravel compatible).

To create a Console Command for STDIO Server, define a class extending `Symfony\Component\Console\Command\Command` and use `PhpLlm\McpSdk\Server` and `PhpLlm\McpSdk\Server\Transport\Stdio\SymfonyConsoleTransport`.

To create a Controller for Server-Sent Events Server, define a controller using `PhpLlm\McpSdk\Server`, `PhpLlm\McpSdk\Server\Transport\Sse\Store\CachePoolStore`, and `PhpLlm\McpSdk\Server\Transport\Sse\StreamTransport`.

To expose tools, use the `#[AsTool]` attribute from `PhpLlm\LlmChain\ToolBox\Attribute\AsTool` in combination with the [Symfony Bundle](https://github.com/php-llm/llm-chain-bundle).
