A real Thursday for a Head of Product: a prioritized board, subtasks, estimates, and a time-blocked schedule. The backlog waits one click away in the right rail.
Most planners are closed boxes that your AI assistant can't see into. Open Sunsama is built to be driven by AI as much as by you:
Paste one URL into your AI assistant, sign in, and click Allow access. That's it: no API keys and no config files.
https://api.opensunsama.com/mcp
Claude (web, Desktop, and mobile)
ChatGPT (paid plans, developer mode)
Coding assistants connect the same way:
| Client | Install |
|---|---|
| Claude Code | claude mcp add --transport http open-sunsama https://api.opensunsama.com/mcp, then run /mcp → Authenticate |
| Cursor |  |
| VS Code |  |
| Any MCP client | Add the URL as a Streamable HTTP server with OAuth |
Then just ask:
"What's on my plate today? Move anything that isn't a P0 or P1 to tomorrow." "Block 9–11am tomorrow for deep work on the launch plan and link it to that task." "Add subtasks to 'Board deck': metrics slide, roadmap slide, asks."

You can also send a key to the hosted server as an X-API-Key header. See Local server & API keys.
Drag tasks onto the calendar and see your whole week at a glance. Blocks link back to their tasks, so estimates meet reality.
Subtasks, rich-text notes, attachments, priority, estimate, and a timer, all in one keyboard-friendly modal.
One task, one timer. Track actual time against your estimate while everything else fades away.
Jump to any task, idea, or setting in a keystroke. Search spans tasks, ideas, and events.
Filter active, completed, or everything, grouped by day with subtask progress.
Trello-style boards for bets and side projects. Promote an idea to a real task when it's time.
