From API Calls to Agent Calls: What I Learned Running a Live MCP Workshop at API Days Singapore

At the API Days Singapore event, over 150 developers gathered to explore innovative API practices through a workshop centered around the Artemis Mission Control API, which simulated a complex lunar mission system. The workshop highlighted the transformative potential of Postman's Agent Mode and Model Context Protocol (MCP), which allow users to automate API workflows using natural language instructions, thereby minimizing manual intervention and maximizing efficiency. Participants experienced firsthand how these features enable seamless creation of scripts, environment setups, and visualizations, shifting API testing from manual scripting to automated processes driven by AI. The session underscored an inflection point in API consumption, where agent-driven interactions are becoming the norm, offering significant time savings and reshaping traditional API development practices. Attendees, many of whom were seasoned Postman users, were surprised by the capabilities they had been unaware of, emphasizing the importance of awareness in leveraging advanced features within familiar tools.
