MCP Explained (mcp-explained.com)

Runlayer has released an updated version of its Model Context Protocol (MCP), aimed at streamlining communication between AI tools. The new spec, dated November 25, 2025, outlines a refined message flow system, although it maintains backward compatibility with previous versions by continuing to use plain `tools/list` and `tools/call` for client-server interactions. This update does not introduce new commands but rather clarifies existing functionalities, ensuring that developers can integrate the MCP into their applications more seamlessly. The significance of this update lies in its potential to enhance interoperability among AI systems, which is critical as the demand for versatile AI solutions grows. By simplifying the interaction protocols, Runlayer is positioning itself as a vital player in the AI infrastructure landscape, facilitating easier deployment and scalability of machine learning models. As the MCP gains traction, it could lead to more standardized practices in AI tool communication, ultimately fostering innovation and collaboration within the AI/ML community.
