Laravel MCP Inspector

A powerful, beautiful inspection and documentation UI for Laravel MCP servers. Think of it as Scalar or Swagger UI, but purpose-built for the Model Context Protocol.

Features

• Interactive Tool Explorer — Browse all MCP tools with descriptions, risk levels, schemas, and annotations
• Live Playground — Execute tools directly from the browser with a built-in JSON-RPC 2.0 client
• Scope Explorer — Visualize scopes and discover which tools each scope unlocks
• Client Connect — Ready-to-copy configuration for Claude Desktop, Cursor, and cURL
• Dark & Light Themes — Beautiful UI with automatic system theme detection
• Zero Config — Auto-discovers your MCP tools from your Laravel config; no manifest scraping
• Self-Contained — Single Blade view with all CSS/JS inline; no build step required

Installation

composer require ovac/laravel-mcp-inspector

The package auto-registers its service provider via Laravel's package discovery.

Quick Start

Once installed, visit:

https://your-app.test/mcp/inspector

The inspector reads your MCP tool definitions directly from your Laravel config (default key: mcp_user_public). No HTTP calls to the MCP manifest — this is what makes it fast and reliable.

Configuration

Publish the config file:

php artisan vendor:publish --tag=mcp-inspector-config

// config/mcp-inspector.php

return [
    'enabled' => env('MCP_INSPECTOR_ENABLED', true),
    'route_prefix' => 'mcp',
    'route_middleware' => ['web'],
    'config_key' => 'mcp_user_public',
    'title' => 'MCP Inspector',
    'theme' => 'auto', // auto|dark|light
];

Options

| Key | Default | Description | |-----|---------|-------------| | enabled | true | Enable/disable the inspector. Set to false in production if needed. | | route_prefix | mcp | URL prefix. Inspector available at /{prefix}/inspector. | | route_middleware | ['web'] | Middleware for the inspector route. Add auth to restrict access. | | config_key | mcp_user_public | The Laravel config key containing your MCP server definition. | | title | MCP Inspector | Title shown in the inspector UI header. | | theme | auto | Default theme: auto, dark, or light. |

Customizing the View

php artisan vendor:publish --tag=mcp-inspector-views

The published view will be in resources/views/vendor/mcp-inspector/.

MCP Config Format

The inspector expects your MCP config to follow this structure:

// config/mcp_user_public.php

return [
    'name' => 'My MCP Server',
    'version' => '1.0.0',
    'description' => 'API tools for my application.',
    'tokens_url' => '/api/mcp/tokens',
    'mcp_endpoint' => '/mcp',

    'tools' => [
        [
            'name' => 'get_user',
            'description' => 'Retrieve a user by their ID.',
            'inputSchema' => [
                'type' => 'object',
                'properties' => [
                    'user_id' => [
                        'type' => 'integer',
                        'description' => 'The user ID.',
                    ],
                ],
                'required' => ['user_id'],
            ],
            'annotations' => [
                'scope' => 'users:read',
                'risk' => 'low',
                'readOnlyHint' => true,
            ],
        ],
    ],

    'scopes' => [
        [
            'name' => 'users:read',
            'description' => 'Read user data.',
            'tools' => ['get_user'],
        ],
    ],
];

Security

For production, you should:

1. Disable the inspector: MCP_INSPECTOR_ENABLED=false
2. Or add authentication middleware:

// config/mcp-inspector.php
'route_middleware' => ['web', 'auth'],

Testing

composer test
