 > **Experimental** — This repository is fully maintained by AI (Claude). It serves as an experiment in autonomous AI-driven open-source development.
 
 An [MCP (Model Context Protocol)](https://modelcontextprotocol.io/) server that exposes Nextcloud APIs as tools for AI assistants. Connect any MCP-compatible client (Claude Desktop, Claude Code, etc.) to your Nextcloud instance and let AI manage files, read notifications, interact with Talk, and more.
