README

gracjankubicki/laravel-mcp-providers integrates external MCP servers with laravel/ai using a class-first tools workflow.

Why this package

• Connect multiple MCP servers from Laravel config.
• Discover tool metadata from MCP (tools/list) into local manifests.
• Generate typed Laravel AI tools from manifests.
• Select tools by ::class (safe, explicit, refactor-friendly).
• Add per-server auth, timeout, retry, and health checks.

Requirements

• PHP ^8.5
• Laravel ^12.0
• laravel/ai ^0.1.2

Installation

composer require gracjankubicki/laravel-mcp-providers

Publish config:

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

Quick Start

1. Configure MCP servers in config/mcp-providers.php.
2. Discover manifests:

php artisan ai-mcp:discover

1. Generate tools:

php artisan ai-mcp:generate

1. Use generated tool classes in your agent:

public function tools(): iterable
{
    return [
        app(\App\Ai\Tools\Generated\Gdocs\GdocsSearchDocsTool::class),
        app(\App\Ai\Tools\Generated\N8n\N8nRunWorkflowTool::class),
    ];
}

Configuration

Config file: config/mcp-providers.php

<?php

return [
    'servers' => [
        'gdocs' => [
            'endpoint' => env('MCP_GDOCS_URL'),
            'auth' => [
                'strategy' => \Laravel\McpProviders\Auth\BearerAuthStrategy::class,
                'token' => env('MCP_GDOCS_TOKEN'),
            ],
            'timeout' => 10,
            'retry' => [
                'attempts' => 3,
                'backoff_ms' => 150,
                'max_backoff_ms' => 1000,
            ],
            'manifest' => resource_path('mcp/gdocs.tools.json'),
        ],

        'n8n' => [
            'endpoint' => env('MCP_N8N_URL'),
            'auth' => [
                'strategy' => \Laravel\McpProviders\Auth\HeaderAuthStrategy::class,
                'header' => 'X-API-Key',
                'value' => env('MCP_N8N_KEY'),
            ],
            'timeout' => 15,
            'manifest' => resource_path('mcp/n8n.tools.json'),
        ],
    ],

    'retry' => [
        'attempts' => 1,
        'backoff_ms' => 100,
        'max_backoff_ms' => 1000,
    ],

    'generated' => [
        'path' => app_path('Ai/Tools/Generated'),
        'namespace' => 'App\\Ai\\Tools\\Generated',
    ],
];

Server fields

• endpoint (string, required): MCP server URL.
• manifest (string, required for discover/generate/registry/toolset flows): local JSON manifest path.
• timeout (int, optional): request timeout in seconds.
• auth (array, optional): auth strategy + params.
• retry (array, optional): attempts, backoff_ms, max_backoff_ms.

CLI Workflow

Discover

Fetches tools/list and writes normalized manifests.

php artisan ai-mcp:discover
php artisan ai-mcp:discover --server=gdocs --dry-run
php artisan ai-mcp:discover --prune --fail-fast

Generate

Generates Laravel AI tool classes from manifests.

php artisan ai-mcp:generate
php artisan ai-mcp:generate --server=gdocs --clean
php artisan ai-mcp:generate --fail-on-collision

Generated output:

• Tool classes, for example: App\Ai\Tools\Generated\Gdocs\GdocsSearchDocsTool
• Per-server toolset classes, for example: App\Ai\Tools\Generated\Gdocs\GdocsToolset
• Aggregate toolset class: App\Ai\Tools\Generated\McpToolset

Sync

Runs discover and generate in sequence.

php artisan ai-mcp:sync

Health

Checks MCP connectivity.

php artisan ai-mcp:health
php artisan ai-mcp:health --server=gdocs --fail-fast

Runtime APIs

GeneratedToolset

public function tools(): iterable
{
    return app(\Laravel\McpProviders\GeneratedToolset::class)
        ->forServers(['gdocs', 'n8n'])
        ->onlyClasses([
            \App\Ai\Tools\Generated\Gdocs\GdocsSearchDocsTool::class,
            \App\Ai\Tools\Generated\N8n\N8nRunWorkflowTool::class,
        ]);
}

Methods:

• all()
• onlyClasses(array $toolClasses)
• exceptClasses(array $toolClasses)

Generated toolset classes

public function tools(): iterable
{
    return app(\App\Ai\Tools\Generated\McpToolset::class)->all();
}

GeneratedToolRegistry (fully dynamic)

$tools = iterator_to_array(
    app(\Laravel\McpProviders\GeneratedToolRegistry::class)
        ->forServers(['gdocs', 'n8n'], [
            \App\Ai\Tools\Generated\Gdocs\GdocsSearchDocsTool::class,
            \App\Ai\Tools\Generated\N8n\N8nRunWorkflowTool::class,
        ]),
    false,
);

HasMcpTools trait

use Laravel\Ai\Contracts\Agent;
use Laravel\Ai\Contracts\HasTools;
use Laravel\Ai\Promptable;
use Laravel\McpProviders\Concerns\HasMcpTools;

final class SupportAgent implements Agent, HasTools
{
    use Promptable;
    use HasMcpTools;

    public function instructions(): string
    {
        return 'Help users with docs and workflow tasks.';
    }

    protected function mcpServers(): array
    {
        return ['gdocs', 'n8n'];
    }

    protected function mcpOnlyToolClasses(): array
    {
        return [
            \App\Ai\Tools\Generated\Gdocs\GdocsSearchDocsTool::class,
            \App\Ai\Tools\Generated\N8n\N8nRunWorkflowTool::class,
        ];
    }
}

Auth Strategies

Built-in strategies:

• \Laravel\McpProviders\Auth\BearerAuthStrategy
• \Laravel\McpProviders\Auth\HeaderAuthStrategy

Custom strategy: implement \Laravel\McpProviders\Contracts\McpAuthStrategy and set servers.<slug>.auth.strategy.

Notes

• Tool selection is class-only (::class). Name-based allowlists are not supported.
• If you return explicit tool instances manually, runtime manifest lookup is not required.
