Model Context Protocol - path to LLM standartization
Tech talk materials: Model Context Protocol (MCP), a framework designed to design and private data source access for Generative AI applications. We’ll discuss how MCP integrates into existing AI system architecture. We will see is it really an app-store moment for Generative AI or not? See examples on: http://github.com/akranga/mcp-workshop/
