AI builders are getting a strange new problem.

The coding part is becoming less lonely.

A good agent can inspect a repository, read current docs, open a browser, run tests, summarize logs, and help move a project forward without waiting for the user to paste every detail into chat.

That is a real change.

It is also why MCP matters. MCP gives AI applications a standard way to connect to external systems: tools, data sources, workflows, and application context. Instead of treating an AI assistant as a text box, you can connect it to the places where work actually happens.
