Integrations Overview
How PrimeTask connects with the rest of your toolset - Apple Calendar and Reminders, Obsidian, deep links from other apps, AI agents via MCP, and data import from tools like Todoist.
PrimeTask is built to stand on its own - your tasks, projects, CRM, and canvases live on your computer, no cloud required. But the rest of your toolset lives in other apps, and the best productivity setups thread them together. This is what the Integrations category covers: every supported way PrimeTask talks to the apps around it.
There are five kinds of integration, and each one has its own home in the docs:
- Apple ecosystem - see your calendar events and sync with Apple Reminders.
- Obsidian - connect a vault to PrimeTask, browse tasks in a sidebar, and promote selected tasks or projects into markdown notes.
- Deep links from other apps - let Apple Shortcuts, Alfred, Raycast, and anything else with a URL scheme drive PrimeTask.
- Bring Your Own AI - let Claude, Cursor, LM Studio, and any MCP-compatible agent read and act on your workspace.
- Importing data - bring your tasks into PrimeTask from tools like Todoist or any CSV.
PrimeTask integrates without needing a cloud account
These integrations work from your computer. PrimeTask doesn't route data through any third-party server.
What you can do
See your Apple Calendar events
next to your tasks, and sync your tasks to Apple Calendar.
Sync tasks with Apple Reminders
bidirectionally on macOS.
Connect Obsidian to a locked PrimeTask Space
and optionally mirror selected work into markdown notes.
Drive PrimeTask from outside
Apple Shortcuts, Alfred, Raycast, or any tool that can open a URL.
Connect an AI agent
Claude, Cursor, LM Studio, and other MCP-compatible tools.
Bring in your existing work
import tasks from Todoist today, with more sources coming.
The five integration surfaces
Apple Calendar and Reminders
PrimeTask integrates with macOS Apple Calendar and Apple Reminders. You can see your calendar events in PrimeTask's calendar views and sync tasks to the calendar, and you can sync Apple Reminders (including Reminders added via Siri or from another Apple device) bidirectionally with PrimeTask tasks.
See Apple Calendar Integration and Apple Reminders Integration. These integrations are macOS only.
Apple integrations are macOS only
They rely on Apple's own Calendar and Reminders frameworks. On Windows, the Apple integration toggles are hidden because there's nothing to connect to.
Obsidian
PrimeTask for Obsidian is the official companion plugin for connecting an Obsidian vault to PrimeTask on the same machine. It lets you browse tasks and projects from one locked Space inside a live sidebar, create tasks from Obsidian, and promote selected tasks or projects into markdown notes when you want them in your vault.
The markdown mirror is opt-in. PrimeTask creates hub files for navigation, but task and project notes appear only when you explicitly promote them.
Deep links - let other apps drive PrimeTask
PrimeTask has its own primetask:// URL scheme. Any tool that can open a URL - Apple Shortcuts, Alfred, Raycast, the terminal - can create tasks, start timers, open specific tasks, and more. Each command type is opt-in so you can enable only what you actually want.
See External Integrations for the full command list and common workflows, and Apple Shortcuts and Deep Links for automation recipes.
Bring Your Own AI (MCP)
PrimeTask includes a built-in MCP server so AI agents can read and interact with your workspace. Connect Claude Desktop, Claude Code, Cursor, LM Studio, or any MCP-compatible client, and the agent can read tasks, create them, work with your canvases, manage CRM, and more - all running locally on your machine.
You choose what the agent is allowed to see and do with fine-grained read and write permissions.
See Bring Your Own AI and PrimeFlow and MCP.
Cloud AI models see what the agent sends them
PrimeTask runs the MCP server on your computer, but an AI agent you connect may send your data to its own cloud provider when it needs a model. Only connect tools you trust, and use Read-only mode if you want the agent to look but not act.
Importing data
The Import Wizard brings your existing tasks into PrimeTask. Todoist and any generic CSV are supported today - more sources are on the way. Column mapping is automatic where the headers make sense, and PrimeTask checks for duplicates before anything is saved.
See Importing Data.
Import early, not late
Move your existing tasks in on your first week. Starting with real work in PrimeTask is faster than rebuilding it from scratch.
Where each integration is configured
| Integration | Set it up in |
|---|---|
| Apple Calendar and Reminders | Integrations Settings |
| PrimeTask for Obsidian | PrimeTask plugin settings inside Obsidian, after enabling External Integrations in PrimeTask |
Deep links (primetask://) | External Integrations Settings |
| Bring Your Own AI (MCP) | External Integrations Settings |
| Importing data | Opens from Settings or from the Tasks and Projects pages |
Things worth knowing
Integrations are opt-in
Nothing here is enabled by default. Each integration is a deliberate toggle, and the first time you turn on Deep Links or the MCP Server, PrimeTask shows a consent explainer so you understand exactly what you're enabling.
Enable only what you use
Every integration is a door. Keep the ones you use open, and the ones you don't closed. The smaller your surface area, the less you have to think about.
Apple integrations are macOS only
Apple Calendar and Apple Reminders are Apple's macOS frameworks. They're available on macOS; on Windows, the integrations settings for them are hidden.
Obsidian is desktop-only
PrimeTask for Obsidian works with the PrimeTask desktop app over a local connection on the same machine. That means it works with Obsidian desktop, not Obsidian Mobile.
Deep links and MCP work on both platforms
The primetask:// URL scheme and the MCP server run on both macOS and Windows.
Data never leaves your computer unless an integration sends it
Apple integrations read and write to macOS's own stores. Deep links and the MCP server run locally. The Import Wizard reads files from your computer. If you connect an AI agent that uses a cloud model, that cloud model receives whatever the agent sends it - connect tools you trust.
Common questions
"Do integrations require Pro?"
No - the integration surface itself is available on every PrimeTask license. A few specific tools inside MCP (for example, CRM tools) require Pro because they access Pro features, but the integration framework isn't tier-gated.
"Can I connect Notion, Google Calendar, or Outlook?"
Not directly today. Use Apple Calendar as the integration point on macOS - events from other calendars that are subscribed in Apple Calendar show up in PrimeTask. For Notion and other tools, the primetask:// scheme can bridge from their side when they support deep links.
"Can I use PrimeTask with Obsidian?"
Yes. Use the official PrimeTask for Obsidian plugin to connect a vault to PrimeTask on the same machine. It supports a live sidebar, explicit vault authorization, a locked Space, and optional markdown mirroring.
"Can AI agents see everything in my workspace?"
They see what you allow. Read permissions and Write permissions are separately controllable. You can also enable and disable the MCP Server entirely at any time.
"How do I move my tasks from another app?"
Start with Importing Data. Today Todoist and Generic CSV imports are supported.
