Apple Calendar MCP server

Apple-MCPs

MCP servers that let an AI client use Apple apps and macOS tools. Create reminders, send messages, check calendars, search mail, manage files, and get directions.

The servers run on your Mac. Your MCP client may send returned data to its model provider, and Apple apps may sync through iCloud or another account. Local execution does not mean the data stays local.

Requires Python 3.11+ and macOS. Uses MCP specification 2026-07-28 and Python SDK 2.x, with support for older client protocol revisions. MIT license.

Install

Install uv, then register the unified server with your client.

Claude Code:

claude mcp add --transport stdio --scope project apple-tools -- uvx apple-tools-mcp

Codex:

codex mcp add apple-tools -- uvx apple-tools-mcp

Other stdio clients:

{
  "mcpServers": {
    "apple-tools": {
      "command": "uvx",
      "args": ["apple-tools-mcp"]
    }
  }
}

Run uvx apple-tools-mcp to start the server directly. Standalone servers use the same approach, such as uvx apple-mcp-mail or uvx apple-calendar-mcp.

Restart your client after installing or upgrading. Call search_tools with calendar health to check discovery without reading app data.

For Claude Desktop, download a server's .mcpb bundle from Releases and double-click it.

Set app-specific safety modes and directories in your client's env settings. The configuration guide lists defaults and options. Mail attachments are disabled until you set APPLEMAILMCPALLOWEDATTACHMENTROOT to a dedicated directory. Files tools only access APPLEFILESMCPALLOWED_ROOTS; macOS may impose further restrictions.

Choose a server

Start with Apple-Tools-MCP. It combines all ten apps and tools below, plus saved defaults, contact routing, Mail thread helpers, undo, briefings, and cross-app workflows.

Choose a standalone server to expose fewer apps to your client:
