Connects Claude to macOS Reminders through Apple's native EventKit framework instead of AppleScript, giving you 10-200x faster CRUD operations with stable UUIDs that survive across sessions. You get 13 tools covering list management, full-text search, today/overdue queries, and complete reminder lifecycle from creation through deletion. Ships three ways: as an MCPB bundle for Claude Desktop/Cowork, a plugin for Claude Code CLI, or an npm package for any MCP client. The Swift binary is signed and notarized by high5 ventures GmbH, handles UTF-8 properly (including CJK and emoji), and runs entirely locally with sub-second latency even on databases with hundreds of reminders. Reach for this when you need reliable, production-ready Reminders integration without timeout issues or brittle positional IDs.
