+
+# MCP Development
+
+## Documentation
+
+Use `search-docs` for detailed Laravel MCP patterns and documentation.
+
+## Basic Usage
+
+Register MCP servers in `routes/ai.php`:
+
+<!-- Register MCP Server -->
+```php
+use Laravel\Mcp\Facades\Mcp;
+
+Mcp::web();
+```
+
+### Creating MCP Primitives
+
+Create MCP tools, resources, prompts, and servers using artisan commands:
+
+```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
+
+```
+
+After creating primitives, register them in your server's `$tools`, `$resources`, or `$prompts` properties.
+
+### Tools
+
+<!-- MCP Tool Example -->
+```php
+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.
+
+<!-- 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,
+    ];
+}
+```
+
+## 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

 - `fortify-development` — ACTIVATE when the user works on authentication in Laravel. This includes login, registration, password reset, email verification, two-factor authentication (2FA/TOTP/QR codes/recovery codes), profile updates, password confirmation, or any auth-related routes and controllers. Activate when the user mentions Fortify, auth, authentication, login, register, signup, forgot password, verify email, 2FA, or references app/Actions/Fortify/, CreateNewUser, UpdateUserProfileInformation, FortifyServiceProvider, config/fortify.php, or auth guards. Fortify is the frontend-agnostic authentication backend for Laravel that registers all auth routes and controllers. Also activate when building SPA or headless authentication, customizing login redirects, overriding response contracts like LoginResponse, or configuring login throttling. Do NOT activate for Laravel Passport (OAuth2 API tokens), Socialite (OAuth social login), or non-auth Laravel features.
 - `laravel-best-practices` — Apply this skill whenever writing, reviewing, or refactoring Laravel PHP code. This includes creating or modifying controllers, models, migrations, form requests, policies, jobs, scheduled commands, service classes, and Eloquent queries. Triggers for N+1 and query performance issues, caching strategies, authorization and security patterns, validation, error handling, queue and job configuration, route definitions, and architectural decisions. Also use for Laravel code reviews and refactoring existing Laravel code to follow best practices. Covers any task involving Laravel backend PHP code patterns.
-- `project-route-structure` — Always apply in this project when creating, moving, or refactoring Laravel route definitions in routes/**/*.php; changing route prefixes, names, middleware, scoped bindings, or route files; or adding frontend-facing endpoints that Wayfinder generates. Documents the KanbanGit route-file layout and grouping conventions.
+- `mcp-development` — Use this skill for Laravel MCP development only. Trigger when creating or editing MCP tools, resources, prompts, or servers in Laravel projects. Covers: artisan make:mcp-* generators, mcp:inspector, routes/ai.php, Tool/Resource/Prompt classes, schema validation, shouldRegister(), OAuth setup, URI templates, read-only attributes, and MCP debugging. Do not use for non-Laravel MCP projects or generic AI features without MCP.
 - `wayfinder-development` — Use this skill for Laravel Wayfinder which auto-generates typed functions for Laravel controllers and routes. ALWAYS use this skill when frontend code needs to call backend routes or controller actions. Trigger when: connecting any React/Vue/Svelte/Inertia frontend to Laravel controllers, routes, building end-to-end features with both frontend and backend, wiring up forms or links to backend endpoints, fixing route-related TypeScript errors, importing from @/actions or @/routes, or running wayfinder:generate. Use Wayfinder route functions instead of hardcoded URLs. Covers: wayfinder() vite plugin, .url()/.get()/.post()/.form(), query params, route model binding, tree-shaking. Do not use for backend-only task
 - `inertia-vue-development` — Develops Inertia.js v2 Vue client-side applications. Activates when creating Vue pages, forms, or navigation; using <Link>, <Form>, useForm, or router; working with deferred props, prefetching, or polling; or when user mentions Vue with Inertia, Vue pages, Vue forms, or Vue navigation.
 - `tailwindcss-development` — Always invoke when the user's message includes 'tailwind' in any form. Also invoke for: building responsive grid layouts (multi-column card grids, product grids), flex/grid page structures (dashboards with sidebars, fixed topbars, mobile-toggle navs), styling UI components (cards, tables, navbars, pricing sections, forms, inputs, badges), adding dark mode variants, fixing spacing or typography, and Tailwind v3/v4 work. The core use case: writing or fixing Tailwind utility classes in HTML templates (Blade, JSX, Vue). Skip for backend PHP logic, database queries, API routes, JavaScript with no HTML/CSS component, CSS file audits, build tool configuration, and vanilla CSS.

+This Font Software is licensed under the SIL Open Font License, Version 1.1.
+This license is copied below, and is also available with a FAQ at:

+-----------------------------------------------------------
+SIL OPEN FONT LICENSE Version 1.1 - 26 February 2007
+-----------------------------------------------------------
+
+PREAMBLE
+The goals of the Open Font License (OFL) are to stimulate worldwide
+development of collaborative font projects, to support the font creation
+efforts of academic and linguistic communities, and to provide a free and
+open framework in which fonts may be shared and improved in partnership
+with others.
+
+The OFL allows the licensed fonts to be used, studied, modified and
+redistributed freely as long as they are not sold by themselves. The
+fonts, including any derivative works, can be bundled, embedded,
+redistributed and/or sold with any software provided that any reserved
+names are not used by derivative works. The fonts and derivatives,
+however, cannot be released under any other type of license. The
+requirement for fonts to remain under this license does not apply
+to any document created using the fonts or their derivatives.
+
+DEFINITIONS
+"Font Software" refers to the set of files released by the Copyright
+Holder(s) under this license and clearly marked as such. This may
+include source files, build scripts and documentation.
+
+"Reserved Font Name" refers to any names specified as such after the
+copyright statement(s).
+
+"Original Version" refers to the collection of Font Software components as
+distributed by the Copyright Holder(s).
+
+"Modified Version" refers to any derivative made by adding to, deleting,
+or substituting -- in part or in whole -- any of the components of the
+Original Version, by changing formats or by porting the Font Software to a
+new environment.
+
+"Author" refers to any designer, engineer, programmer, technical
+writer or other person who contributed to the Font Software.
+
+PERMISSION AND CONDITIONS
+Permission is hereby granted, free of charge, to any person obtaining
+a copy of the Font Software, to use, study, copy, merge, embed, modify,
+redistribute, and sell modified and unmodified copies of the Font
+Software, subject to the following conditions:
+
+1) Neither the Font Software nor any of its individual components,
+in Original or Modified Versions, may be sold by itself.
+
+2) Original or Modified Versions of the Font Software may be bundled,
+redistributed and/or sold with any software, provided that each copy
+contains the above copyright notice and this license. These can be
+included either as stand-alone text files, human-readable headers or
+in the appropriate machine-readable metadata fields within text or
+binary files as long as those fields can be easily viewed by the user.
+
+3) No Modified Version of the Font Software may use the Reserved Font
+Name(s) unless explicit written permission is granted by the corresponding
+Copyright Holder. This restriction only applies to the primary font name as
+presented to the users.
+
+4) The name(s) of the Copyright Holder(s) or the Author(s) of the Font
+Software shall not be used to promote, endorse or advertise any
+Modified Version, except to acknowledge the contribution(s) of the
+Copyright Holder(s) and the Author(s) or with their explicit written
+permission.
+
+5) The Font Software, modified or unmodified, in part or in whole,
+must be distributed entirely under this license, and must not be
+distributed under any other license. The requirement for fonts to
+remain under this license does not apply to any document created
+using the Font Software.
+
+TERMINATION
+This license becomes null and void if any of the above conditions are
+not met.
