Calendar app MCP for accessing macOS Calendar events and reminders
Most planning and project tracking work still happens through a UI a human drives. Calendar MCP server moves it into the conversation instead. Calendar app MCP for accessing macOS Calendar events and reminders.
An MCP (Model Context Protocol) server that provides access to macOS Calendar.app events and reminders for use with Claude and other AI assistants.
The server publishes 11 tools. What each one is for:
get_events — Retrieve events for a specific date rangeget_reminders — Retrieve reminders for a specific date rangelist_calendars — List all available calendarsget_today_summary — Get a summary of today's events and reminderssearch — Search for events and reminders containing a specific termget_current_time — Get the current date and time in any timezoneconvert_time — Convert a time from one timezone to anotherlist_timezones — List available timezones, optionally filtered by regionTools — The Tools tool exposed by this serverResources — The Resources tool exposed by this serverPrompts — The Prompts tool exposed by this serverInstallation goes through your MCP client rather than a global install: point it at calendar-app-mcp on PyPI and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
Among the planning and project tracking options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Calendar's toolset — get_events, get_reminders, list_calendars and 8 more — is a fair guide to whether it matches your workflow.
This entry was verified against Calendar's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.
