What MCP Is and Why It Helps Agents Call Tools

Jacob Bank has been building AI agents since before they were cool. While the rest of us were just figuring out what ChatGPT could do, Jacob was already 13 years deep into agent research. Now, as founder and CEO of Relay.app, Jacob is making AI agents accessible to everyone, from customer success teams to businesses that install slip-resistant floors.

Jacob has a fascinating prediction: within a year, agents will be able to handle virtually any task you do on your computer. The real question won't be "can an agent do this?" but rather "how do I teach, manage, and trust my agent?"
