• Creating MCP servers (web or local)
• Building tools that AI clients can call
• Defining prompts for reusable AI interactions
• Exposing resources for AI context
• Protecting MCP servers with OAuth or Sanctum
• Testing MCP servers, tools, prompts, and resources

Rule Categories by Priority

• server-create-register - Create and register web or local MCP servers

2. Tools (HIGH)

• tool-create - Create tools with input/output schemas, DI, and annotations
• tool-responses - Text, error, structured, streaming, and multi-content responses

3. Prompts & Resources (MEDIUM)

• prompt-create - Create prompts with arguments, validation, and responses
• resource-create - Create resources and resource templates with URI patterns

4. Authentication (HIGH)

Essential Patterns

Creating an MCP Server

<?php

namespace App\Mcp\Servers;

use Laravel\Mcp\Server;
use Laravel\Mcp\Server\Attributes\Instructions;
use Laravel\Mcp\Server\Attributes\Name;
use Laravel\Mcp\Server\Attributes\Version;

#[Name('Weather Server')]
#[Version('1.0.0')]
#[Instructions('This server provides weather information.')]
class WeatherServer extends Server
{
    protected array $tools = [
        CurrentWeatherTool::class,
    ];

    protected array $resources = [];

    protected array $prompts = [];
}

Registering in routes/ai.php

use App\Mcp\Servers\WeatherServer;
use Laravel\Mcp\Facades\Mcp;

Mcp::web('/mcp/weather', WeatherServer::class);
Mcp::local('weather', WeatherServer::class);

Creating a Tool

<?php

namespace App\Mcp\Tools;

use Illuminate\Contracts\JsonSchema\JsonSchema;
use Laravel\Mcp\Request;
use Laravel\Mcp\Response;
use Laravel\Mcp\Server\Attributes\Description;
use Laravel\Mcp\Server\Tool;

#[Description('Fetches the current weather for a location.')]
class CurrentWeatherTool extends Tool
{
    public function handle(Request $request): Response
    {
        $location = $request->get('location');

        return Response::text("The weather in {$location} is sunny, 72°F.");
    }

    public function schema(JsonSchema $schema): array
    {
        return [
            'location' => $schema->string()
                ->description('The location to get the weather for.')
                ->required(),
        ];
    }
}

How to Use

Read individual rule files for detailed explanations and code examples.

Each rule file contains:

• YAML frontmatter with metadata (title, impact, tags)
• Brief explanation of why it matters
• Bad Example with explanation
• Good Example with explanation
• Laravel 13 and PHP 8.3 specific context and references
