Documented tools (15)

From project documentation. A server handshake does not verify each tool’s description or behavior.

item_archive

Move an item to the archive (hidden from normal views).

Permanently delete an item — cannot be undone.

item_edit

Update title, notes (empty string clears), tags, URL; upsert or remove fields. Unreferenced fields stay untouched.

Full item: title, category, tags, notes, fields. Concealed values stay hidden unless reveal: true. Accepts op://… or vaultId + itemId.
