Model Context Protocol (MCP) is changing AI application development by allowing AI models to dynamically discover and interact with external tools, moving beyond rigid APIs to intelligent systems. This hands-on session covers MCP architecture and shows how to build AI applications using open-source tools like FastMCP, Python, and SQLite. Learn to design MCP servers, ensure data consistency with resources, debug using MCP Inspector, and integrate with FastAPI backends. Whether for automation, enterprise, or consumer apps, gain practical knowledge of this emerging protocol shaping the future of AI integration.
