Icloud Calendar

Overview

Icloud Calendar is a Model Context Protocol (MCP) server: Manage Apple iCloud Calendar through a reliable CalDAV MCP server. In practice that means any MCP-compatible AI assistant can call Icloud Calendar's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package icloud-calendar-mcp speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need ICLOUD_USERNAME, ICLOUD_APP_PASSWORD. The current release is v0.1.3, published under the MIT license, with source at IceyWu/icloud-calendar-mcp on GitHub.

Icloud Calendar is listed under Productivity 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.
