Things 3 Setup
Connect Things 3 to Dex for bi-directional task sync. No account needed. Everything stays on your Mac. Works offline.
What This Enables
Once connected, Dex can:
- Task Sync: Create tasks in Things 3 when you add them in Dex, and vice versa
- Daily Plan: Pull in tasks you created in Things and merge them into your plan
- Completion Sync: Complete a task in either place — it syncs to the other
- Priority Mapping: P0/P1 tasks go to your Today list, P2/P3 to Anytime
- Pillar Mapping: Dex pillars map to Things Areas for organized task views
Privacy
- Everything is local. Things 3 uses AppleScript — no cloud API, no tokens, no accounts
- Tasks sync between two apps on YOUR Mac. Nothing leaves your machine
- No credentials to store. No tokens to expire. No OAuth flows
- Works completely offline
When to Run
- User types
/things-setup
- User asks about connecting Things 3
- User wants task sync with a Mac-native app
- During
/integrate-mcp if Things is mentioned
- During onboarding if user mentions Things 3
Setup Flow
Step 1: Platform Check
Things 3 is macOS only. Verify:
- Check if running on macOS (
process.platform === 'darwin' or uname check)
- If not macOS:
Things 3 is a macOS-only app. It won't work on this platform.
For cross-platform task sync, consider:
- /todoist-setup (works everywhere)
- /trello-setup (web-based)
Stop here.
Step 2: Check if Already Connected
- Read
System/integrations/config.yaml
- If
things.enabled: true, skip to Step 7 (Reconfigure)
- If not configured, continue
Step 3: Check if Things 3 is Installed
Run a quick AppleScript test:
osascript -e 'tell application "System Events" to (name of processes) contains "Things3"'
Or check if the app exists:
ls /Applications/Things3.app 2>/dev/null || ls "$HOME/Applications/Things3.app" 2>/dev/null
If Things 3 is not found:
I can't find Things 3 on your Mac.
Things 3 is available from the Mac App Store:
https://apps.apple.com/app/things-3/id904280696
Once installed, run /things-setup again.
Stop here.
If found:
Things 3 detected. This is the simplest integration to set up — no accounts or API keys needed.
Everything stays on your Mac and works offline. Ready?
Wait for confirmation.
Step 4: Add the things3-mcp Server
Check the user's MCP configuration. If things3-mcp is not listed:
- Explain:
I need to add the Things 3 connector to your Dex configuration.
This uses a lightweight AppleScript bridge — no accounts, no API keys.
It talks directly to Things 3 on your Mac.
- Add to the user's
.mcp.json:
{
"things3-mcp": {
"command": "npx",
"args": ["-y", "things3-mcp"],
"env": {}
}
}
- Tell the user the MCP server needs to restart for changes to take effect.
Step 5: Test the Connection
Run a quick test to verify AppleScript access:
-
List Things Areas:
osascript -e 'tell application "Things3" to get name of areas'
-
List Things Projects:
osascript -e 'tell application "Things3" to get name of projects'
If macOS prompts for AppleScript permission:
macOS is asking for permission to control Things 3. Click "OK" to allow.
This is a one-time prompt. Things 3 uses AppleScript for local communication —
no network access is involved.
Show results:
Connection test passed.
Your Things 3 setup:
- Areas: [list of areas]
- Projects: [list of projects]
If the test fails, jump to Troubleshooting.
Step 6: Configure Mapping
First, read System/pillars.yaml and extract the user's pillar id and name fields. If pillars are empty/not yet configured, prompt the user to run /quarter-plan first.
Map Dex pillars to Things Areas:
Now let's map your Dex pillars to Things Areas.
Your Dex pillars (from System/pillars.yaml):
[list each pillar name, numbered]
Your Things Areas:
[list from Step 5]
I'll suggest a mapping — adjust if needed:
| Dex Pillar | Things Area |
|------------|-------------|
| [pillar 1 name] | [best match or "[pillar 1 name]"] |
| [pillar 2 name] | [best match or "[pillar 2 name]"] |
...
Does this mapping look right? I can create any missing Areas in Things.
If areas don't exist, offer to create them (run once per missing pillar):
osascript -e 'tell application "Things3" to make new area with properties {name:"[pillar name]"}'
Then ask about sync behavior:
One more question: How should task sync work?
1. **Auto-sync** — Tasks sync automatically between Dex and Things
2. **Ask each time** — I'll confirm before syncing each task
Most people prefer auto-sync. Which do you want?
Step 7: Save Configuration
Write to System/integrations/config.yaml — update the things section. Build area_mapping dynamically from the user's pillars: use each pillar's id as the key and the confirmed Things Area name as the value.
things:
enabled: true
configured_at: YYYY-MM-DD
mcp_server: things3-mcp
auth_type: none
task_sync: true
sync_mode: auto
area_mapping:
[pillar_id]: [Things Area name]
features:
task_sync: true
external_task_merge: true
If the file already exists, only update the things: section. Preserve other integration configs.
Step 8: Capability Cascade
Now that Things is connected, highlight what changes:
Things 3 is connected.
Here's what changes now:
- **/daily-plan** syncs tasks from Things into your morning plan
- **Task creation** in Dex mirrors to Things (P0/P1 → Today, P2/P3 → Anytime)
- **Task completion** syncs both ways — finish in either app
- **Pillars → Areas** keep your Things organized by Dex structure
No accounts. No tokens. No expiration. Works offline.
Tip: Tasks you create directly in Things will appear in your next /daily-plan.
Troubleshooting
Things 3 Not Installed
Things 3 must be installed from the Mac App Store. It's a paid app (~$49.99).
Once installed, run /things-setup again.
AppleScript Permission Denied
macOS may block AppleScript access. To fix:
- Open System Settings > Privacy & Security > Automation
- Find your terminal app (Terminal, iTerm2, etc.)
- Enable the toggle for Things3
- Retry the setup
"Things3 got an error" Messages
Things 3 must be running for AppleScript to work. Open Things 3, then retry.
Areas Not Showing
If no Areas appear during setup:
- Open Things 3
- Go to Settings > General
- Make sure Areas are enabled
- Create at least one Area, then retry
Sync Conflicts
If a task is edited in both Dex and Things between syncs:
- Dex is the source of truth for task status
- Things is the source of truth for task title edits
- Notes merge (Dex context is appended, not overwritten)
Reconfiguration
If the user runs /things-setup when already configured:
- Show current config from
System/integrations/config.yaml
- Offer options:
- Update pillar-to-area mapping
- Change sync mode (auto vs. ask)
- Re-test the connection
- Disconnect Things
Disconnect Flow
If user wants to disconnect:
- Update
System/integrations/config.yaml:
things:
enabled: false
- Confirm: "Things 3 is disconnected. Tasks will no longer sync. Run
/things-setup anytime to reconnect."
