Claude Agent SDK for Laravel

Build AI agents with Claude Code as a library in your Laravel applications. This SDK wraps the Claude Code CLI to give your app access to file operations, bash commands, code editing, web search, subagents, and more.

Requirements

• PHP 8.2+
• Laravel 12 or 13
• Claude Code CLI (npm install -g @anthropic-ai/claude-code)
• Anthropic API key

Installation

composer require mohamed-ashraf-elsaed/claude-agent-sdk-laravel

Publish the config:

php artisan vendor:publish --tag=claude-agent-config

Add your API key to .env:

ANTHROPIC_API_KEY=your-api-key

Quick Start

Simple Query

use ClaudeAgentSDK\Facades\ClaudeAgent;

$result = ClaudeAgent::query('What files are in this directory?');

echo $result->text();       // Final text result
echo $result->costUsd();    // Cost in USD
echo $result->sessionId;    // Session ID for resuming

With Options (Fluent API)

use ClaudeAgentSDK\Options\ClaudeAgentOptions;

$options = ClaudeAgentOptions::make()
    ->tools(['Read', 'Edit', 'Bash', 'Grep', 'Glob'])
    ->permission('acceptEdits')
    ->maxTurns(10)
    ->maxBudgetUsd(5.00)
    ->cwd('/path/to/project');

$result = ClaudeAgent::query('Find and fix the bug in auth.php', $options);

if ($result->isSuccess()) {
    echo $result->text();
}

Streaming Responses

use ClaudeAgentSDK\Messages\AssistantMessage;
use ClaudeAgentSDK\Messages\ResultMessage;

foreach (ClaudeAgent::stream('Refactor the User model') as $message) {
    if ($message instanceof AssistantMessage) {
        echo $message->text();
    }

    if ($message instanceof ResultMessage) {
        echo "\nDone! Cost: $" . $message->totalCostUsd;
    }
}

Stream with Callback

$result = ClaudeAgent::streamCollect(
    prompt: 'Create a REST API for products',
    onMessage: function ($message) {
        if ($message instanceof AssistantMessage) {
            Log::info($message->text());
        }
    },
    options: ClaudeAgentOptions::make()->tools(['Read', 'Write', 'Bash']),
);

echo $result->text();

Options Reference

Fluent Builder

$options = ClaudeAgentOptions::make()
    ->tools(['Read', 'Write', 'Edit', 'Bash', 'Grep', 'Glob'])
    ->disallow(['WebFetch'])
    ->model('claude-sonnet-4-5-20250929')
    ->permission('acceptEdits')
    ->maxTurns(15)
    ->maxBudgetUsd(10.00)
    ->maxThinkingTokens(8000)

    ->cwd('/path/to/project')
    ->env('MY_VAR', 'value')
    ->settingSources(['project'])
    ->useClaudeCodePrompt('Also follow PSR-12.')
    ->betas(['context-1m-2025-08-07'])
    ->permissionPromptToolName('my_custom_tool')
    ->resumeSessionAt('2025-01-15T10:30:00Z')
    ->allowDangerouslySkipPermissions();

From Array

$options = ClaudeAgentOptions::fromArray([
    'allowed_tools' => ['Read', 'Bash'],
    'permission_mode' => 'bypassPermissions',
    'max_turns' => 5,
    'max_budget_usd' => 5.00,
    'max_thinking_tokens' => 10000,
]);

System Prompts

// Custom string
$options->systemPrompt('You are a Laravel expert. Always use Eloquent.');

// Claude Code preset (includes default agent behavior)
$options->useClaudeCodePrompt();

// Claude Code preset with additions
$options->useClaudeCodePrompt('Follow PSR-12 and use strict types.');

Permission Modes

Mode	Behavior
default	Ask for permission on each tool use
acceptEdits	Auto-accept file edits, ask for others
dontAsk	Don't ask but log decisions
bypassPermissions	Skip all permission checks
plan	Create a plan but don't execute

Custom Permission Handler

For fine-grained control over tool permissions, use canUseTool() to register a callback that approves, denies, or modifies each tool invocation:

use ClaudeAgentSDK\Permissions\PermissionResultAllow;
use ClaudeAgentSDK\Permissions\PermissionResultDeny;

$options = ClaudeAgentOptions::make()
    ->canUseTool(function (string $toolName, array $input) {
        if ($toolName === 'Bash' && str_contains($input['command'] ?? '', 'rm -rf')) {
            return new PermissionResultDeny('Destructive commands not allowed');
        }
        if ($toolName === 'Write') {
            return new PermissionResultAllow(
                updatedInput: array_merge($input, ['file_path' => '/sandbox' . $input['file_path']])
            );
        }
        return new PermissionResultAllow();
    });

Return PermissionResultAllow to approve (optionally with modified input), or PermissionResultDeny with a reason to block the tool call.

Hooks

Run shell commands before or after Claude uses tools. The SDK supports all 12 hook events:
