Can the integration accidentally delete important notes?

The `delete_note` tool performs a permanent deletion. We recommend instructing your AI agent to always confirm before executing any deletion. You can also use `get_note_version` to review note history before making changes.

Does it support shared or team notes?

Simplenote is designed for personal note management. This integration accesses notes tied to the authenticated user's account only. Team collaboration features are not available through the Simperium API.

Does it support Markdown formatting?

Yes. Simplenote stores plain text, so Markdown syntax is preserved as-is when you create or update notes. The Simplenote clients will render Markdown formatting natively.
