Agentic thinking is changing how we build software—from linear scripts to dynamic, decision-making workflows. In this lightning talk, we’ll explore how to design, build, and ship real AI agents using Postman Flows and Model Context Protocol (MCP). You’ll see how APIs become tools in an agent’s toolbox, and how Flows can orchestrate autonomous, API-driven behavior. We’ll walk through practical patterns, show working examples, and share lessons from building agentic systems that actually ship.
