Microsoft To Do

Microsoft To Do is a cloud-based task management application that lets users create, organize, and track task lists, tasks, checklist items, and reminders across devices via Microsoft Graph

Verdict

The Microsoft To Do MCP lets your team create, update, and complete tasks across any To Do list without leaving Switchy. @mention it to add action items during planning sessions, check off subtasks as you work, or pull a snapshot of what's due today. Writers and PMs get the most value — they can turn meeting notes into trackable tasks in seconds, then mark them done when the work ships. The MCP exposes 22 tools covering task CRUD, checklist items, attachments, and list management. OAuth setup requires Tasks.ReadWrite scope; deletions are permanent and cascade to subtasks.

Common use cases

Turn meeting notes into trackable tasks
Check off subtasks as features ship
Pull today's due items at standup
Archive completed sprints by deleting lists
Add file attachments to task context

Setup

Setup guide

11. In your Switchy workspace, navigate to Settings → Integrations and click Connect next to Microsoft To Do. 2. You'll be redirected to Microsoft's OAuth consent screen; sign in with your Microsoft account and grant the Tasks.ReadWrite permission (this lets Switchy read and modify your To Do lists). 3. After approving, you'll land back in Switchy with a green Connected badge. 4. Open any Project and type a message that @mentions Microsoft To Do — for example '@Microsoft To Do create a task called Test integration in my default list'. 5. The MCP will confirm the task was created and return its ID; open the Microsoft To Do app or web interface to verify the task appears. 6. If the connection fails, check that your Microsoft account has To Do enabled and that you granted the correct scope during OAuth.

What teammates see: by default, memories from Microsoft To Do are scoped to the Project (PROJECT visibility) - you can mark any memory PRIVATE or share it ORG-wide.
