Overview

What is PHP Model Context Protocol Server SDK?

This project provides a PHP implementation of the Model Context Protocol (MCP), enabling you to build servers that can provide context (data and tools) to Large Language Models (LLMs). It is designed for PHP developers who want to expose custom functionalities and data to LLMs using the standardized MCP protocol.

How to use PHP Model Context Protocol Server SDK?

Install the SDK via Composer with composer require james2037/mcp-php-server. Requires PHP 8.1 or higher. Define tools and resources using PHP attributes, then instantiate a Server, add capabilities (ToolsCapability, ResourcesCapability), connect a transport (StdioTransport or HttpTransport), and call $server->run(). Example scripts are provided in the examples/ directory.

Key features of PHP Model Context Protocol Server SDK

Create MCP-compliant servers with ease
Expose Tools and Resources to LLMs
Supports Stdio and HTTP transports
JSON-RPC message handling built in
Attribute-based configuration for tools and resources

Use cases of PHP Model Context Protocol Server SDK

Provide LLMs with custom executable tools (e.g., an echo tool)
Serve data and content to LLMs via resources (e.g., a static greeting)
Build local MCP servers running via STDIO
Deploy web‑accessible MCP servers behind Apache/Nginx with PHP-FPM/mod_php

Frequently asked questions

What are the prerequisites for using this SDK?

PHP 8.1 or higher and Composer for dependency management are required.

What transports are supported?

The SDK provides StdioTransport for command-line based servers and HttpTransport for HTTP-based servers (compatible with standard PHP web server environments like Apache/Nginx with PHP-FPM/mod_php).

How do I run an HTTP server?

For development, start PHP’s built-in server: `php -S localhost:8000 examples/http_server.php`. For production, configure your web server (e.g., Nginx or Apache) to route requests to the `http_server.php` script.

How do I test an HTTP server?

Send JSON-RPC requests via curl, for example: `curl -X POST -H "Content-Type: application/json" -d '{"jsonrpc":"2.0","method":"tools/call","params":{"name":"echo","arguments":{"message":"Hello"}},"id":1}' http://localhost:8000/`.

How are tools and resources configured?

Use PHP attributes such as `#[Tool]`, `#[Parameter]`, and `#[ResourceUri]` on classes that extend the base Tool or Resource classes.
