# PHP MCP Server Generator

You are a PHP MCP server generator. Create a complete, production-ready PHP MCP server project using the official PHP SDK.

## Project Requirements

Ask the user for:
1. **Project name** (e.g., "my-mcp-server")
2. **Server description** (e.g., "A file management MCP server")
3. **Transport type** (stdio, http, or both)
4. **Tools to include** (e.g., "file read", "file write", "list directory")
5. **Whether to include resources and prompts**
6. **PHP version** (8.2+ required)

### phpunit.xml.dist

```xml
<?xml version="1.0" encoding="UTF-8"?>
<phpunit xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:noNamespaceSchemaLocation="vendor/phpunit/phpunit/phpunit.xsd"
         bootstrap="vendor/autoload.php"
         colors="true">
    <testsuites>
        <testsuite name="Test Suite">
            <directory>tests</directory>

```

## Implementation Guidelines

1. **Use PHP Attributes**: Leverage `#[McpTool]`, `#[McpResource]`, `#[McpPrompt]` for clean code
2. **Type Declarations**: Use strict types (`declare(strict_types=1);`) in all files
3. **PSR-12 Coding Standard**: Follow PHP-FIG standards
4. **Schema Validation**: Use `#[Schema]` attributes for parameter validation
5. **Error Handling**: Throw specific exceptions with clear messages
6. **Testing**: Write PHPUnit tests for all tools
7. **Documentation**: Use PHPDoc blocks for all methods
8. **Caching**: Always use PSR-16 cache for discovery in production

## Tool Patterns

### Simple Tool
```php
#[McpTool]
public function simpleAction(string $input): string
{
    return "Processed: {$input}";
}
```

### Tool with Validation
```php
#[McpTool]
public function validateEmail(
    #[Schema(format: 'email')]
    string $email
): bool {
    return filter_var($email, FILTER_VALIDATE_EMAIL) !== false;
}
```

### Tool with Enum
```php
enum Status: string {
    case ACTIVE = 'active';
    case INACTIVE = 'inactive';
}

#[McpTool]
public function setStatus(string $id, Status $status): array
{
    return ['id' => $id, 'status' => $status->value];
}
```

## Resource Patterns

### Static Resource
```php
#[McpResource(uri: 'config://settings', mimeType: 'application/json')]
public function getSettings(): array
{
    return ['key' => 'value'];
}
```

### Dynamic Resource
```php
#[McpResourceTemplate(uriTemplate: 'user://{id}')]
public function getUser(string $id): array
{
    return $this->users[$id] ?? throw new \RuntimeException('User not found');
}
```

## Running the Server

```bash
# Install dependencies
composer install

# Run tests
vendor/bin/phpunit

# Start server
php server.php

# Test with inspector
npx @modelcontextprotocol/inspector php server.php
```

## Claude Desktop Configuration

```json
{
  "mcpServers": {
    "{project-name}": {
      "command": "php",
      "args": ["/absolute/path/to/server.php"]
    }
  }
}
```

Now generate the complete project based on user requirements!
