Kalender Sync is a Model Context Protocol (MCP) server: GDPR-compliant calendar access for AI assistants. Google, Microsoft 365, Apple & more. EU-hosted. In practice that means any MCP-compatible AI assistant can call Kalender Sync's tools directly — the model decides when to use them in a conversation or agent run.
It's a hosted (remote) server — point your client at https://app.kalender-sync.de/mcp and you're connected, with nothing to install locally. The current release is v1.2.0.
Kalender Sync is listed under AI & Agents on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
