Before MCP, most of my time coding went to moving context by hand. A Trello card would say a project's images were ready in a linked Google Drive folder. The code lived in the repo. So I'd read the card, open the folder, decide, paste a summary into chat, wait for the change, then switch back to Trello and mark it done. I had stopped noticing how much of the day that ate.
Two MCP servers close that gap. The Trello server exposes the board as callable tools, so Cursor can list cards, read a card's description and checklist, and post a comment or move the card when it's finished. The Google Drive server does the same for the files: search the folder, read the doc, pull the specific asset the card points at. The agent resolves the card and its linked source itself, applies the change in the repo, then writes status back to the board. No copy-paste bridge, no re-describing the brief every round.
The real gain is continuity. I stop dropping out of the problem to go fetch context, so I can work through a string of changes without rebuilding the brief each time. Small fixes I used to batch for later, a missing list from a copy doc, a title that disagreed between two pages, get done while I'm still in the session.
This does not rescue a bad ticket. If the card is vague, the output will be too. What it does well is remove the distance between the systems we already trust and the place the code gets written. Wire those in, write specific cards, and the agent stops waiting on you to paste the world into chat.
