php-sdk vs omnisim

php-sdk: The MCP PHP SDK is the official toolkit for implementing Model Context Protocol servers and clients in PHP. It offers a framework-agnostic API, allowing developers to expose PHP application functionality to AI agents or integrate with MCP servers.; omnisim: OmniSim is a conversational simulator where AI agents can build scenes and wire controllers based on natural language descriptions, all running over a simple HTTP/JSON protocol. It integrates a Newton physics engine and supports various robotic platforms, serving as a powerful tool for agent development and robotics research.
