If 2024 was the year of the chatbot, 2026 is the year of agentic infrastructure. Tools like Claude Code have transitioned from experimental novelties to primary actors inside local development environments. They don’t just suggest code; they build, test, and deploy it. But to do this effectively, they need a bridge. That bridge is the Model Context Protocol (MCP). As we shift toward this agent-first world, the way we think about tunneling has fundamentally changed. We aren’t just tunneling to show a client a demo; we are tunneling to give an autonomous agent access to our local IDE, databases, and terminal. The stakes are correspondingly higher.
