With Model Context Protocol now GA in Copilot Studio, practitioners face a new question: when should I use MCP versus connectors versus direct API calls? This session provides a practical decision framework based on Microsoft's guidance. We'll explore why MCP shines for centrally-managed tools (update once, all agents get the change), when connectors win for rapid prototyping, and where direct API calls still make sense. Through side-by-side demos of the same integration built three ways, you'll leave with a decision tree for your architecture choices.
