It runs beside your instance rather than inside it — as a uvx command, a container or a Kubernetes workload — and signs in with an app password over Basic Auth. Coverage is unusually wide for one server: WebDAV files, Notes, Calendar, Contacts, Deck, Tables and more, well past a hundred tools. The project is AGPL-3.0 and maintained independently of Nextcloud itself.
