MCP Development

Documentation

Use search-docs for detailed Laravel MCP patterns and documentation.

Basic Usage

Register MCP servers in routes/ai.php:

use Laravel\Mcp\Facades\Mcp;

Mcp::web();

Creating MCP Primitives

Create MCP tools, resources, prompts, and servers using artisan commands:

php artisan make:mcp-tool ToolName        # Create a tool

php artisan make:mcp-resource ResourceName # Create a resource

php artisan make:mcp-prompt PromptName    # Create a prompt

php artisan make:mcp-server ServerName    # Create a server

After creating primitives, register them in your server's $tools, $resources, or $prompts properties.

Tools

use Laravel\Mcp\Server\Tool;
use Laravel\Mcp\Server\Request;
use Laravel\Mcp\Server\Response;

class MyTool extends Tool
{
    public function handle(Request $request): Response
    {
        return new Response(['result' => 'success']);
    }
}

Registering Primitives in a Server

Each MCP server must explicitly declare the tools, resources, and prompts it exposes.

use Laravel\Mcp\Server;

class AppServer extends Server
{
    protected array $tools = [
        \App\Mcp\Tools\MyTool::class,
    ];

    protected array $resources = [
        \App\Mcp\Resources\MyResource::class,
    ];

    protected array $prompts = [
        \App\Mcp\Prompts\MyPrompt::class,
    ];
}

Verification

1. Check routes/ai.php for proper registration
2. Test tool via MCP client

Common Pitfalls

• Running mcp:start command (it hangs waiting for input)
• Using HTTPS locally with Node-based MCP clients
• Not using search-docs for the latest MCP documentation
• Not registering MCP server routes in routes/ai.php
• Do not register ai.php in bootstrap.php; it is registered automatically.
• OAuth registration supports custom URI schemes (e.g., cursor://, vscode://) for native desktop clients via mcp.custom_schemes config
