Best When

A macOS user with Things 3 needs AI agents to read from and write to their personal task manager as part of productivity automation.

Avoid When

You don't use Things 3, or need team/shared task management — use Todoist, Linear, or JIRA MCPs.

Use Cases

• Creating and updating tasks in Things 3 from productivity agents
• Reading today's task list from daily planning agents
• Adding tasks to inbox from capture agents processing notes or emails
• Managing project tasks from project management agents
• Integrating Things 3 with calendar and email agents for unified workflow
• Querying and completing tasks from focus session agents

Not For

• Non-macOS/iOS users (Things 3 is Apple-platform exclusive)
• Teams needing shared task management (Things 3 is personal)
• Todoist, Linear, or JIRA users — use appropriate MCPs
