MCP SDK for PHP - First Stable Release

We're pleased to announce the first stable release of the PHP implementation of the Model Context Protocol (MCP) SDK. This release marks successful client compatibility testing with the official "Everything MCP Server".

Major Achievement

  • Successful compatibility test with @modelcontextprotocol/server-everything, the official MCP test server
  • Execution of prompts, tools, and resources through the MCP Web Client in a standard cPanel web hosting environment

Core Functionality

  • Complete implementation of the MCP protocol specification
  • Robust client-side implementation with web-based testing interface
  • Cross-SDK compatibility (tested with Python and TypeScript implementations)
  • Interactive testing and debugging tools

MCP Web Client Features

  • Comprehensive testing interface for MCP servers
  • Real-time execution of prompts, tools, and resources
  • Detailed JSON-RPC message logging
  • FastCGI and standard web hosting compatibility

Installation

composer require logiscape/mcp-sdk-php:^1.0

Important Notes

  • Review by experienced developers is recommended for production deployments

Use Cases

  • Development of web-based AI clients
  • Integration of large language models with custom data sources
  • Creation of specialized AI tools and interfaces
  • Testing and prototyping of MCP implementations

Ongoing Development

Future releases will focus on:

  • Performance optimizations
  • Additional security features
  • Enhanced error handling
  • Extended testing coverage
  • Protocol updates as the MCP specification evolves

Feedback

We welcome community input on:
