# MCP Development ## Documentation Use `search-docs` for detailed Laravel MCP patterns and documentation. For MCP UI apps (interactive HTML resources), read `references/app.md` — it covers the full architecture, host theming CSS variables, tool-to-UI linking patterns, library scripts (Tailwind, Alpine via `Library`), and real-world examples. ## Basic Usage Register MCP servers in `routes/ai.php`: <!-- Register MCP Server --> ```php use Laravel\Mcp\Facades\Mcp; Mcp::web('/mcp/demo', \App\Mcp\Servers\AppServer::class); ``` ### Creating MCP Primitives ```bash 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 php artisan make:mcp-app-resource DashboardApp # Create a UI app (2 files) ``` After creating primitives, register them in your server's `$tools`, `$resources`, or `$prompts` properties. ### Tools <!-- MCP Tool Example --> ```php use Illuminate\Json\Schema\JsonSchema; use Laravel\Mcp\Request; use Laravel\Mcp\Response; use Laravel\Mcp\Server\Tool; class MyTool extends Tool { protected string $description = 'Describe what this tool does'; public function schema(JsonSchema $schema): array { return [ 'name' => $schema->string()->description('The name parameter')->required(), ]; } public function handle(Request $request): Response { $request->validate(['name' => 'required|string']); return Response::text('Hello, '.$request->get('name')); } } ``` ### Registering Primitives in a Server <!-- Register Primitives in MCP Server --> ```php 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, ]; } ``` ## MCP UI Apps For MCP UI apps, read `references/app.md` — it covers quick start examples, full architecture, AppMeta/Csp/Permissions, `#[RendersApp]` tool linking, library scripts (Tailwind/Alpine via `Library`), host theming CSS variables, and real-world patterns. ## 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
