Which general topic do you have

I am proud to introduce a powerful extension for Nextcloud that revolutionizes how applications interact with its core calendaring and contact services.

Our custom-developed solution exposes Nextcloud’s CalDAV and CardDAV interfaces as modern, developer-friendly REST/JSON APIs, enabling seamless integration with virtually any application, regardless of platform or language.

No more dealing with legacy protocols — developers can now access, create, or update calendar events and contact records using simple HTTP requests and standard JSON payloads.

But that’s not all.

This platform also supports MCP (Message-Centric Protocol) mode using Server-Sent Events (SSE), making it natively compatible with intelligent agents and AI-driven automation tools. Real-time updates, continuous event streams, and smart synchronization capabilities are now at your fingertips

Hello @Harokku_Kyaputen,

welcome to the Nextcloud community! :handshake:

sounds good. It would be great you publish this app as native NC app without..

All API endpoints require HTTP Basic Authentication with your Nextcloud credentials.

sounds problematic.

For now it is a design decision as I wanted to be “release independant” from nextcloud (but still glued to the underlying Sabre server) and I did not want to use AppAPI that did not meet my requirements (as it is more app driven than API driven).
