Why MCP Hookups, Not Just Models, enable Agent Potential in Production

The unsexy part of the agent story is the part that decides whether it ships or stalls. Frontier models can plan, refactor, write tests, and read your codebase. What they can't do, on their own, is reach your real services. They don't know your Postgres schema, can't tail your deploy logs, can't hit your auth provider. Without a connection to the world outside the editor, the agent is a brilliant writer in a sealed room.
