Overview Installation

Overview

ox-mcp is a Model Context Protocol server that connects your AI assistant to Open-Xchange services. It provides access to email via IMAP and SMTP, Sieve filter management, CalDAV calendars, and CardDAV contacts through a unified interface. Instead of switching between applications, your AI can now interact with these services as callable tools.

The server runs locally through the npm package @rheopyrin/ox-mcp, which communicates via stdio on your machine. You'll need an API key to authenticate with your Open-Xchange instance. The latest release is v0.1.2, distributed under the MIT license with full source code available at Rheopyrin/ox-mcp on GitHub.

ox-mcp is listed in the Communication category on mcp.site and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim this listing to verify ownership and keep the details current.
