# 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) ## Project Structure ``` {project-name}/ ├── composer.json ├── .gitignore ├── README.md ├── server.php ├── src/ │ ├── Tools/ │ │ └── {ToolClass}.php │ ├── Resources/ │ │ └── {ResourceClass}.php │ ├── Prompts/ │ │ └── {PromptClass}.php │ └── Providers/ │ └── {CompletionProvider}.php └── tests/ └── ToolsTest.php ``` ## File Templates ### composer.json ```json { "name": "your-org/{project-name}", "description": "{Server description}", "type": "project", "require": { "php": "^8.2", "mcp/sdk": "^0.1" }, "require-dev": { "phpunit/phpunit": "^10.0", "symfony/cache": "^6.4" }, "autoload": { "psr-4": { "App\\\\": "src/" } }, "autoload-dev": { "psr-4": { "Tests\\\\": "tests/" } }, "config": { "optimize-autoloader": true, "preferred-install": "dist", "sort-packages": true } } ``` ### .gitignore ``` /vendor /cache composer.lock .phpunit.cache phpstan.neon ``` ### README.md ```markdown # {Project Name} {Server description} ## Requirements - PHP 8.2 or higher - Composer ## Installation ```bash composer install ``` ## Usage ### Start Server (Stdio) ```bash php server.php ``` ### Configure in Claude Desktop ```json { "mcpServers": { "{project-name}": { "command": "php", "args": ["/absolute/path/to/server.php"] } } } ``` ## Testing ```bash vendor/bin/phpunit ``` ## Tools - **{tool_name}**: {Tool description} ## Development Test with MCP Inspector: ```bash npx @modelcontextprotocol/inspector php server.php ``` ``` ### server.php ```php #!/usr/bin/env php <?php declare(strict_types=1); require_once __DIR__ .
