FAQ from Omnifocus

Does the server directly access the OmniFocus database?

No. All interaction goes through the official Omni Automation API via osascript -l JavaScript calling app.evaluateJavascript(). No direct database access.

What are the system requirements?

macOS (required for osascript), OmniFocus 4.6+ installed, Node.js 18+, and macOS automation permission for OmniFocus (granted on first use).

Can I create recurring tasks?

No. The server can read and analyze recurring patterns, but cannot create repeat rules due to Omni Automation API limitations.

Does the server support perspective management?

No. The Omni Automation API is read-only for perspectives, so the server cannot manage perspectives.

Can I link files with http/https URLs?

No. add_linked_file only accepts file:// URLs; OmniFocus rejects http/https links.
